Zwiki 0.27.0 2004-02-02

    Summary

        New, faster page hierarchy implementation; access keys everywhere;
	page management form and action icons in plone; utf-8; bugfixes.

    Upgrade notes

        Two upgrade issues this month:

	If you have non-ascii characters in your page names or content:
	the default skin used to specify iso-8859-1 character encoding; it
	now specifies utf-8.  So your wiki's character encoding may
	change, and non-ascii characters may no longer display
	correctly. You'll have to convert these manually (see
	http://zwiki.org/IssueNo0682 for tips).

	If you were running the 0.27cvs code: 
	you might be unable to view or add pages after upgrading to 0.27
	final. To fix, visit SOMEPAGE/updateWikiOutline, or /upgradeAll.
	(If this happens to you and you weren't running 0.27cvs, I'd like
	to hear from you).

    Changes

      General

	* page hierarchy is now cached in a wiki Outline object, stored as
	  a (hidden) folder attribute, instead of being generated from the
	  page parents attribute every time. All hierarchy operations
	  should now be fast (so it's safe to enable show_subtopics and
	  show_navlinks in large wikis) and hopefully scalability (eg
	  conflict errors) is no worse.
	
	* fixed a reStructuredText import bug with zope 2.7 (IssueNo0687)

	* under rare conditions viewing a page could give 'pagenameandX'
	  attribute error

	* new next/previousPageUrl methods

	* upgradeAll now checks each page's parents information and
	  repairs it if necessary; it also regenerates the saved wiki
	  outline. This restores any pages missing from the contents view.
	  You can also visit /checkParents to fix a single page.

	* revert a mistaken "fix" to
	  manage_afterAdd/afterClone/beforeDelete (IssueNo0684)

      Skins and content

	* the default skin now specifies the utf-8 charset, like
	  zwiki_plone, and the wikiname regular expressions can now handle
	  multi-byte utf-8 encoding. This may cause some page names or
	  wiki content to be displayed incorrectly after upgrading, but we
	  don't attempt any automatic migration right now. (Simon,
	  traldar, Samotnik)

	* added a number of access keys, following w3c guidelines, and
	  made them work in all views, both default and plone skin. Alt-0
	  displays a list.

	* don't hide subtopics in minimal display mode any more;
	  revert to simple "subtopics" heading

	* plone: make document actions (external edit, send to,
	  print) appear on wiki pages (Alexander Limi)

	* plone: clean up the comment form a bit, and show the page
	  management form when the user has permission

	* default, plone: make diffs slightly more bookmarkable

	* default, plone: the useroptions template was not redirecting
	  quite right, so options didn't stick (anonymous)
	
      Mail and messages

	* when using "edits" policy, comments weren't sending mailouts
	(Joachim Bauch)

      Tracker

	
Zwiki 0.26.0 2004-01-02

    Summary

        Epoz support, skin layout tweaks, bugfixes.

    Upgrade notes

        No special upgrade issues.

    Changes

      General

	* wiki links in HTML pages work again (IssueNo0664)

	* simplify and fix locale awareness of bare WikiNames - these
	should now recognize upper- and lower-case characters defined by
	the system locale, if configured.

	* possible fix for startup problem with recent zope 2.7 beta
	(DateTime Syntax Error) (IssueNo0649)

	* add python 2.3 encoding declaration in LocalizerSupport.py
	to prevent startup warning

      Skins and content

        * default, zwiki_plone: the editform now uses Epoz 0.x, if
	installed, to edit HTML-only pages in WYSIWYG fashion. To see
	this, install the Epoz 0.x product; edit one of your pages and
	change it's type to HTML; edit again to see the new form.  See
	http://zwiki.org/ZwikiAndEpoz for more.
	
	* default: streamline editform and other forms' layout (remove
	editform tabindex attributes, they only add confusion; make page
	type more prominent at top right; add cancel button; remove
	unnecessary large headings)

	* default: include backlinks & diff links in the links panel.
	It now includes pretty much all site and page views.

	* default: rearrange access keys: use r for recent changes, c for
	contents, u for (un)subscribe, b for backlinks

	* default: fix minor typos and errors

	* zwiki_plone: add back the by-line in wikipage_view (limi)

	* zwiki_plone editform: update to the new Plone 2 forms format;
	fix tabindex so it works again; rewrote the help texts (limi)

      Mail and messages

	* some mailing list headers in mailouts were empty when there was
	no mail_from property. Now they use mail_replyto in that
	case. (IssueNo0673)

      Tracker

        * disable old broken issue navigation links

Zwiki 0.25 2003-12-01

    Summary

        Fully-functional non-DTML wikis are now supported and default;
	refactored default skin with macros, CSS and SkinnedFolder
	support; more zwiki features available in CMF/Plone; quicker
	comments, improved search, easy tracker setup, much code
	refactoring, etc.

    Upgrade notes

	Many changes, you may want to hold off and watch KnownIssues for a
	week or two.

	The page_type property is no longer a simple string. Customized
	skin templates should continue to work. Downgrading from this
	release may cause temporary problems.
	
	If you have DTML-using wikis, you will need to take steps to
	re-enable DTML pages after this upgrade. You can either:
	1. re-enable DTML: set the allow_dtml property as described below;
	or 2. become a non-DTML wiki: remove or rename your RecentChanges,
	SearchPage, UserOptions, IssueTracker or FilterIssues pages. If
	you're using the default skin, the site navigation links will
	adjust automatically; if you're using the zwiki_plone skin you'll
	need to make such links yourself.

	This release includes additional CMF/Plone action links;
	re-install Zwiki in your CMF/Plone site to see these
	(or add them manually in portal_types -> Wiki Page -> actions).
	
    Changes

      General

        * no DTML by default

	  DTML is off again by default, for real this time.  (These days
	  it's too great a surprise for people who just want a wiki.)  To
	  enable DTML in pages you must now set a true 'allow_dtml'
	  property on your wiki folder or above. (A 'no_dtml' property,
	  any value, will override this and disable all DTML as before.)
	  See also "new skin-based views" below.

	* new page type objects

	  Pages now store their type as a PageType object, rather than a
	  string.  These encapsulate behaviours that are specific to each
	  page type. The page_type attribute is no longer accessible via
	  the ZMI, and it is no longer a simple string, though in simple
	  DTML usage it will return the same value as before (DTML and
	  skin authors take note). Legacy skin templates should continue
	  to work.

	* search has been enhanced; it now lists matching page names and
	  prints text excerpts, with or without a catalog 
	  (Dean Goodmanson, Simon Michael)

	* comments no longer re-render the whole page, so are much quicker
	  on large pages

	* when enabled (via show_subtopics property), subtopics are now
	  always displayed, except in minimal display mode.  This makes
	  hierarchy more useful, but also will make large wikis slower and
	  use more cpu time when bots crawl the wiki.

	* By default, don't leave placeholder pages when renaming any
	  more; configurable in Default.py

	* permissions fix: since splitting out the UI class, methods such
	  as editform were not respecting permissions

	* we no longer need to set up an allowed_page_types property to
	  disable WWML in plone

	* Unconfirmed fix for the DateTime error with zope 2.7/python 2.x
	  (IssueNo0649)

	* more robust reporting of structured text formatting errors

	* fix typo in updateCatalog's exception logging

	* a SITE_CATALOG property no longer causes problems for setupCatalog
	  (it will use the specified catalog name)

	* fix a missing import which allowed problem pages to stop upgradeAll

	* code refactoring: extract Editing and Utils mixins, many
	  cleanups.  

	* new defaultPage, defaultPageId, defaultPageUrl methods look for
	  a default_page property, or a page named "FrontPage", or the
	  first page in the folder. Other new methods include: pageCount,
	  pageIdsMatching, pageNamesMatching, *Url helper methods for the
	  site navigation links
	
	* reparenting cleanup, bugfixes

	* allow creation of new pages from a webdav-locked page

	* cleanups, bugfixes, speedups for rename & delete plus some new
	  utility methods. rename was doing an unnecessary updatebacklinks
	  pass and reparenting all offspring not just it's children and
	  just generally trying too hard. 

	* set correct last editor when updating backlinks during rename

	* found the bugger that was leaving all those placeholder pages
	  when renaming

	* log more verbosely during renames to show what's going on.

	* add update backlinks functionality to delete, similar to rename,
	  so you can enter a name in the page management form to have all
	  links redirected there after deletion (a "replacement page").

	* disable subtopics display entirely unless there's a true
	  show_subtopics folder property

	* fix "global name 'p' is not defined" when adding pages via plone
	  UI

      Skins and content

        * default, zwiki_plone: new skin-based views - instead of the
	  DTML-based RecentChanges, SearchPage, UserOptions, IssueTracker
	  and FilterIssues pages, new wikis now use skin-based views
	  (similar to editform etc) by default: recentchanges, searchwiki,
	  useroptions, issuetracker and filterissues.  As usual, these can
	  be changed by customizing the page template of the same name, in
	  the wiki folder or in the CMF or SkinnedFolder skins tool.  If
	  you later want to switch back to page-based versions, eg for
	  easier tweaking, you can call /setupDtmlPages and /setupTracker.
	
	* default: the main wikipage template has been completely redone
	  using METAL macros and CSS (Dan McMullen)

	* default: the default skin uses a new UI method, stylesheet, to
	  find it's stylesheet. This can be customized with a File named
	  either "stylesheet" or "stylesheet.css". A page template or dtml
	  method may also be used, in which case the stylesheet will be
	  dynamic and will be reloaded for each page view.

	* default: adopt the latest zwiki.org look as default - use a
	  sans-serif font by default, use full browser window, indent page
	  content, cleaner/more styled context and subtopics. Has been
	  tested only with mozilla 1.6; assume other browsers can cope.

	* default: smarter site navigation links; work with page-based or
	  skin-based views as appropriate; show issues link only if there
	  are issues

	* make our skin directories available to FileSystemSite if
	  installed, to support a SkinnedFolder setup

	* contextX and renderNestingX are skinnable versions of context
	  and renderNesting, which may be used to present page hierarchy 
	  in more flexible ways. (Dan McMullen)

	* fix an obsolete try except that was hiding errors in the default
	  wikipage template, show such errors in the browser as elsewhere

	* default, zwiki_plone editform: reduce default text area height
	  to 20; fix tab indexes so save button is last

	* FrontPage: note webdav lock permissions in EE setup docs

	* RecentChanges, recentchanges: make the log note bold when summaries are
	  displayed, too; hide buttons when there is no catalog; simplify
	  the code, clean up and indent

	* HelpPage: content, formatting updates

	* instead of a horizontal rule, use a styled heading for comments
	  section, consistent with subtopics

	* zwiki_plone: fix the contents link, rename recent changes link

	* default backlinks: the upper checkboxes were being ignored

	* default, zwiki_plone recentchanges: international characters in
	  page names were being quoted

	* default, zwiki_plone: move the comments heading style to
	  stylesheet and use the anchor "comments" instead of "messages"

	* zwiki_plone: move some tabs into the "actions" category, for
	  now, after discussing with limi

	* default contents: fix string: typo

	* default, zwiki_plone: make filter issues accessible via link
	  from issue tracker and vice-versa

	* default: use standard stylesheet and site links panel in all views

	* zwiki_plone: install actions (tabs) for the new skin views
	  (leave useroptions disabled)

	* default, zwiki_plone: fix the issuetracker & filterissues forms

	* default, zwiki_plone: latest zwiki.org search form with hit counts

	* remove the contents link from page context in full mode, it's
	  superfluous now

	* remove confusing #parents tag from default content files.. we
	  don't need it

      Tracker

	* setupTracker now does not install dtml pages by default, sets up
	  an issue_colours property, creates one dummy issue if there are
	  none, and redirects to the issue tracker afterward

	* make status counts work for statuses other than
	  open/pending/closed

	* new methods: issueCount, hasIssues


Zwiki 0.24 2003-11-01

    Summary

        Bugfixes.

    Upgrade notes

        Reminder: the plone skin disables DTML-based pages (like
	RecentChanges) by default now. If you wish to enable those you'll
	need to remove the ZWiki/skins/zwiki_plone/no_dtml.dtml file after
	an upgrade.

	In the ZMI add menu, "ZWiki Web" is now just "ZWiki".

    Changes

      General

	* change ZMI add menu's 'Wiki' to 'ZWiki', to locate it back
	  beside 'ZWiki Page'

	* hide the WWML page type option by default in cmf/plone, by
	  installing an allowed_page_types property on the portal folder
	  during install (for limi) 

	* make new hierarchy methods more robust when a page has bogus
	  parents; also, check new parents more carefully. reparent() now
	  also accepts fuzzy page names & ids, removes duplicates, and
	  leaves parents sorted. The backlinks form's parent text field
	  now interprets the string as a single page name, like the page
	  management form.  (IssueNo0633, IssueNo0634)

	* context(with_siblings=1) no longer includes the current page's
	  children, which I think was a regression. (IssueNo0629)

	* fix missing import that confused error messages during upgrades

	* log individual page upgrade errors in upgradeAll rather than
	  aborting the whole process

	* log STX rendering errors (eg from tables) rather than breaking
	  the page

	* added/cleaned up tests, all tests pass again, the
	  CMF/Plone-specific tests now work with (and require) plone 2 and
	  all it's dependencies.

	* dublin core fixes, so wiki pages should show correct
	  modification time, ownership etc. in CMF/Plone

      Skins and content

	* allow access to diff screens (but not full history button)
	  without 'View history' permission

	* the access key for backlinks is now L everywhere

	* zwiki_plone: tidy up wikinav_portlet a little

      Mail and messages

	* fixed never-encountered bug in subscriber list upgrading
	  (IssueNo0540)


Zwiki 0.23 2003-10-12

    Summary

        Permission renames, useful page/catalog/tracker setup methods,
	more functional default skin with slow but nifty hierarchy
	navigation options, default content updates, bugfixes.

    Upgrade notes

        Three permissions have been renamed, and wherever you have
	configured these ('Add ZWiki Webs', 'Add ZWiki Pages' & 'Zwiki:
	Add comments to pages') you'll have to set them again with the new
	names. You may want to review your settings before upgrading.
	Sorry; it should be easy to write a script to automate this, I
	don't have one.

	As usual, but especially if upgrading from a very old version, it
	doesn't hurt to visit SOMEPAGE/upgradeAll once as manager
	(except, it may be slow in large wikis). This will ensure all your
	pages have the latest attributes and have been rendered with the
	latest code. Do this if you want to use the subtopics display
	option below.

	Regulations support was not working and has been dropped - I don't
	expect this to affect you, but if I'm wrong join the discussion on
	http://zwiki.org/RegulatingYourPages .
	
    Changes

      General

	* permissions & ZMI menu renames for usability/consistency:

	  - 'Add ZWiki Web' in the ZMI add menu is now 'Add Wiki'. 
	    ('Add ZWiki Page' remains as is to avoid changing the meta type).

	  - 'Add ZWiki Webs' permission is now 'Zwiki: Add wikis'

	  - 'Add ZWiki Pages' permission is now 'Zwiki: Add pages'

	  - 'Zwiki: Add comments to pages' permission is now 
	    'Zwiki: Add comments'

	* new wiki setup methods

	 From any page, visit these urls as manager to quickly set up
	 standard wiki features:

	 - setupPages - install default wiki pages (like Add Wiki in the ZMI)

	 - setupDtmlMethods - install index_html and standard_error_message

	 - setupCatalog - install or configure a wiki catalog, with
	 appropriate configuration for optimizing large wikis.  CMF/Plone
	 notes: this one is called automatically by the CMF install
	 script, to simplify installation. It adds all the indexes and
	 metadata that Zwiki expects from a catalog (see setupCatalog or
	 http://zwiki.org/ZwikiAndZCatalog for a list). NB these will
	 apply for all catalogable plone objects, not just zwiki pages,
	 but will
	 (hopefully) be empty/harmless for the non-pages.

	 - setupTracker - configure the wiki & catalog for issue tracking
	 and install the IssueTracker and FilterIssues pages

	 These also work inside CMF/Plone, except for setupDtmlMethods
	 which may not work there.
	
	* pages() now always returns brains with complete metadata, even
	  when a partial catalog is present. This allows a number of
	  things, eg creating/renaming in a cmf/plone site where
	  setupCatalog has not been called, to keep working, at the cost
	  of more zodb access (IssueNo0623 and others)

	* Hierarchy navigation links and subtopics links

	 If your wiki folder has a true 'show_navlinks' boolean property,
	 the default skin in full mode will show a navigation links panel.
	 These are GNU Info-style next/previous/up links, with N/P/U quick
	 access keys respectively. See zwiki.org for an example.

	 If your wiki folder has a true 'show_subtopics' boolean property,
	 and the user is currently in full mode (their zwiki_displaymode
	 cookie is "full"): pages with children will have a "subtopics"
	 panel displayed, after the document part and before any
	 messages. (This will appear after the next edit, or after running
	 upgradeAll.)

	 Subtopics display can also be turned permanently on or off for a
	 specific page, and all pages below it in the hierarchy, by
	 setting an option in the default skin's editform (requires
	 'Zwiki: Reparent pages' permission). We may find a way to
	 simplify this later, ideas welcome.

	 Both of these options (navlinks and subtopics) are expensive in a
	 large wiki, even if you set up a catalog to optimize it (and you
	 should). When active they will slow page rendering down a lot
	(ballpark figure: zwiki.org FrontPage goes from 0.1 to ~1 second).
	
        * regulations support dropped - this has been broken for some
	  time, and noone used it anyway because it makes life too
	  complicated.  I'll be removing and mothballing the code next
	  month, assuming no-one steps forward to make it worth
	  keeping. We might revive it in a simpler form later.

	* there is a new PREFER_USERNAME_COOKIE global option in
	  Defaults.py; set this true to allow username cookie to override
	  authenticated name. Useful for a simple community wiki protected
	  by a single shared login.

	* STX footnote links were broken by 0.22's refactoring (IssueNo0605)

	* disable iframe tags by default, like javascript (IssueNo0588)

	* wiki link regexp tweak: remove unnecessary restriction on the
	  end character of bare urls, and allow single-character remote
	  parts in interwiki links

	* fix a bug in rename where children's parents field was not
	  updated, leading to an error when you tried to view that child

	* make renaming's update backlinks pass more robust and more
	  verbose (IssueNo0594, James Collier)

	* make post-delete redirect work when the parent is freeform-named

	* saving a page via ftp or webdav after removing the blank line
	  between headers and text was giving an error. (Dan McMullen)
	  This should fix the error (but may not do what's wanted..)

	* misc. code cleanups: move admin-related methods to Admin.py;
	  begin long-awaited Parents.py cleanup; move the WikiNesting code
	  into ParentsSupport and simplify; various new methods.

	* convert more unit tests to ZopeTestCase; make MockZWikiPage a
	  bit more useful; first unit tests for cmf/plone and page
	  hierarchy functionality

      Skins and content

	* default: the default skin has been rearranged somewhat, as at
	  zwiki.org; cf recent GeneralDiscussion. Less gray, widgets
	  grouped into panels, site links moved to top, annoying quote and
	  user bookmarks dropped, navigation links support. Note the
	  various site links appear only if you have a corresponding page,
	  following the names used at zwiki.org.

	* default wikipage: freeform names now work when reparenting via
	  the page management form. Only a single parent can be set there
	  now.

	* zwiki_plone wikipage_view: fix freeform links in the ancestor
	  list (IssueNo0603)

	* default, zwiki_plone editform: when creating a new page, default
	  to the wiki's default page type, not the parent page's type

	* default editform: fix an editform breakage with zope 2.5,
	  apparently due to a TAL difference

	* default, zwiki_plone backlinks: make the reparent form action
	  url more robust, to fix reparenting in CMF/Plone (IssueNo0610)

	* default backlinks: always explicitly list a page's parents, as
	  well as it's backlinks; don't show reparent controls if user
	  does not have permission
	
	* a wikipage() UI method has been added, which you can use (in
	  portal_types -> Wiki Page -> actions -> view) to allow a non-CMF
	  skin like CommonPlace to be used inside a CMF/Plone
	  site. Possibly just a temporary hack.

	* quick access keys in the default skin have been rearranged - see
	  QuickReference
	
	* RecentChanges: latest zwiki.org code,
	  catalog-optimization-compatible, comment out old brute-force
	  code which should no longer be needed, fix last edit times when
	  there is no timezone cookie

	* UserOptions: make it function inside a CMF/Plone site too
	  (useful with alternate skins); remove no longer used quote &
	  bookmarks options; include valid Pacific timezones (except for a
	  couple which DateTime doesn't support)
	  (IssueNo0595, James Collier)

	* SearchPage: catalog search improvements: make help text always
	  visible, search only within current wiki, also show page title
	  hits (but the default code assumes Title index is a TextIndexNG2
	  with left globbing and case folding enabled, otherwise may not
	  work so well)

        * zwiki_plone: the experimental skin-based versions of DTML pages
	  are now generated automatically and the tracker has been added
	  (untested). These are: recentchanges, searchwiki, useroptions,
	  issuetracker, filterissues. 

      Mail and messages

	* mailout signatures now include the precise message url

	* a whitespace + horizontal rule separator is inserted before the
	  messages section. You'll see this after next page edit or
	  upgradeAll.

	* update catalog after subscribing/unsubscribing (fixes non-updating
	  "other page subscriptions" when a catalog is present)

	* new 'fewer_threads' option, disabled by default, tries to gather
	  comments under a single thread per page per month

      Tracker

	* creating issue pages without first setting issue_* folder
	  properties didn't work.. it should work now.  The necessary
	  folder properties will be installed as needed.

	* IssueTracker: remove "how to report a bug" link;
	  latest-catalog-compatible code (so we don't always return all
	  pages)

	* FilterIssues: move search form to the top; use pages() method to
	  ensure we search only this wiki; latest-catalog-compatible code

Zwiki 0.22 2003-09-10

    Summary

	Memory efficiency/performance/scalability improvements; simpler
	page types and DTML control; zwiki_plone and default skin updates;
	wikimail tweaks; STX images; bugs, fixes, features. 
	
    Upgrade notes

	Control of page types and DTML has been simplified. NB in this
	release wikis tend to allow embedded DTML by default.  To disallow
	it, add a 'no_dtml' property as described below.

	The backlinksFor() and pages() methods have changed; Title() is
	now preferred instead of title_or_id(); and RESPONSE is no longer
	provided in the default namespace for skin templates (see below).
	If you have DTML pages or customized skin templates using these
	things, they may need to be updated.

	If using a catalog, you should add the Title field to your
	metadata if not already present. Use of title_or_id is being
	phased out but you may want to leave it in your catalog until
	Zwiki 0.23 to be safe.

    Changes

      General

	* page type cleanups and DTML changes: deprecated page types have
	been removed, as have the non-DTML-supporting STX and HTML types.
	DTML is now controlled as follows: a 'no_dtml' property (value
	doesn't matter) on page or folder will disable Zwiki's DTML
	functionality below that point. You can set this on the root
	folder to disable it server-wide.

	 NB: non-CMF wikis, and CMF/Plone wikis which don't use the
	zwiki_plone skin, are DTML-enabled by default for the moment.  
	The zwiki_plone skin includes an empty 'no_dtml' method which
	disables DTML. To enable it in all your CMF/Plone wikis, you need
	to remove ZWiki/skins/zwiki_plone/no_dtml.dtml and restart zope,
	(or switch to a similar skin without that file).

	* the 'allowed_page_types' lines property is supported again.  It
	does not prevent setting any type, but is used to restrict the
	types offered in the default edit form. All supported types are
	offered by default. The type of new pages, if unspecified, now
	defaults to the first of the wiki's allowed page types.  The
	'standard_page_type' property is no longer supported.
	
	* zodb caching improvements for large wikis: many operations which
	used to load all or many pages into cache will no longer do so if
	a suitably configured catalog is available. This can greatly
	reduce cache activity and peak per-transaction memory usage for
	large wikis, improving performance and server uptime. Renaming and
	deleting are still relatively memory-expensive; more optimizations
	to come. To fully benefit, you should have a wiki catalog with
	meta_type, id, Title, path, canonicalLinks, isIssue indexes and
	id, Title, issueColour, parents, links metadata (IIRC). NB most
	wikis don't need to worry about this. See
	http://zwiki.org/MemoryUsage for some more details.
	
	* the pages() method now returns catalog brains if possible,
	otherwise brain-like objects (if there is no catalog), rather than
	(expensive) page objects. It will also pass keyword arguments to
	the catalog, if there is one, so is convenient for searching among
	the pages of the current wiki (only). pageObjects() provides the
	old behaviour.

	* likewise, backlinksFor() now returns either catalog results or
	similar brain-like objects. Old custom backlinks templates should
	still work without upgrading, except in this (unlikely) case: when
	there is a catalog with meta_type, path, and canonicalLinks
	indexes but without page_url and linkTitle metadata.
	(with help from Magog)

	* the rendering code uses a simpler, more memory-efficient
	pre-rendering and pre-linking scheme.  The relative_urls property
	is no longer supported.

	* DTML-enabled pages now invoke DTML only when there is code in
	the page, to avoid unnecessary parsing and reduce our memory
	footprint.

	* wiki link titles (last edited info in tooltips) have been
	disabled for the moment.

	* three new boolean properties are supported, on page or folder:
	use_wikiname_links, use_bracket_links, use_doublebracket_links,
	for configuring your linking syntax of choice (lightly tested).
	You'll need to run /clearCache or /upgradeAll after changing these.

	* be smarter about choosing where to store uploaded files - when
	checking for the "uploads" subfolder, make sure it is a subobject
	of the wiki folder, and make sure it is folderish.

	* we support the STX :img: syntax, finally (IssueNo0601, etc.)

	* bare urls containing ; (semicolon) are now recognized
	(DeanGoodmanson)

	* renaming fixes: add or remove brackets when appropriate; when
	updating links, tolerate edit failures (eg due to regexp
	recursion); also replace changed ids
	
	* pages are now reindexed after being reparented, when a catalog
	is present

	* catalog lookup behaviour has changed:
        "By default, Zwiki looks for an object named 'Catalog' in this wiki
        folder (will not acquire) or a 'portal_catalog' (can acquire).
        If a SITE_CATALOG property exists (can acquire), Zwiki will look
        for an object by that name (can acquire); if no such object
        exists, or SITE_CATALOG is blank, no catalog will be used."

	* new catalogId() method returns id of the catalog in use, or
	NONE. Requires 'Manage properties' permission.

	* hasCatalog() is now public

	* getPath() is now supported

	* Title() is now always provided and is equivalent to pageName().
	Use of title_or_id is now deprecated; DTML pages and skin
	templates should use Title instead, to take best advantage of
	future catalog optimizations etc.

	* other misc. new methods: pageName(), summary(), size(),
	cachedSize(), cachedDtmlSize()

	* ChangeLog is no longer provided in releases for the moment, to
	simplify maintenance

      Skins and content

	* RESPONSE is no longer provided in the namespace for DTML Method
	skin templates; they must use REQUEST.RESPONSE (code simplification)

	* new methods recentchanges(), searchwiki(), useroptions() provide
	experimental skin-based implementations of these wiki pages, which
	can be used when DTML pages are not allowed.  The included
	implementations are preliminary and unskinned (but customizable);
	they are DTML methods so as to reuse code from the evolving
	page-based implementations, but you can also use page templates.

	* if a SiteMap page exists, the "site contents" link in full mode
	will point there instead. Also contents() now accepts a 'here'
	page name argument to allow this page to control the "you are
	here".  See http://zwiki.org/SiteMap for an example.

	* default skin: reduce subject field width again to "fix" too-wide
	comment form

	* default editform: show the page rename field as in the plone skin
	(but display only if the user has rename permission)

	* default search field & SearchPage: use GET when searching, for
	more useful URLs

	* default, zwiki_plone editform: show the STX and HTML page types
	with "(+ DTML)" when DTML is allowed

	* default, zwiki_plone editform: clear the "sticky" last log note when
	creating a page

	* default, zwiki_plone subscribeform: fix other subscribed page links

	* zwiki_plone: initial cut of a wiki navigation portlet for Plone. 
	(AlexanderLimi)

	* zwiki_plone: Added File Uploads Overview template (AlexanderLimi)

	* zwiki_plone: made the wiki editform explanation more clear. 
	(AlexanderLimi)

	* zwiki_plone editform: make the convenient alt-s (save) key work
	again

	* zwiki_plone: fix links in ancestor list

	* content/basic/RecentChanges.stxdtml, SearchPage.stxdtml,
	UserOptions.stxdtml, and content/tracker/IssueTracker.stxdtml,
	FilterIssues.stxdtml: latest catalog-optimized versions from
	zwiki.org

	* content/basic/SearchPage.stxdtml: remove other search tools for
	now

      Mail and messages

	* fix message id inconsistencies preventing proper threading in
	mail clients (IssueNo0587)

	* mailout policy change: don't mail out page rename and deletions
	with default 'comments' policy. Also don't mail out when
	placeholder pages are created during rename.

	* don't put brackets around mail sender's name in message
	headings.. too clever

	* the 'auto_subscribe' option now automatically subscribes a
	page's creator, as well as commenters. Also it's possible to use
	this property on a page now.

	* the subscribe/unsubscribe methods now support a redirectURL
	REQUEST parameter, which makes them more flexible

	* fix unicode/UnixMailbox problem.  Comments made on the
	place-holder page left after a rename would not appear, since the
	text was unicode. Removed the i18n for the moment so this works.

	* try a fix for non-formatted comment headers in certain timezones
	(IssueNo0552)


Zwiki 0.21.1 2003-08-03

    Summary

	Bugfix release.

    Changes

	* support old Wiki Folders (IssueNo0571)

	* drop confusing allowed_page_types option

	* fix scroll to bottom after comment

Zwiki 0.21 2003-08-01

    Summary

	A number of important bugfixes & usability tweaks for wiki mail
	and the Plone/CMF skin, and preliminary optional Purple Numbers
	support (fine-grained linking).
	
    Upgrade notes

        Should be routine. Upgrading to this release is recommended.

    Changes

      General

	* CMF/Plone: Wiki Folder is no more! use ordinary folders instead.
	NB this means you can't create a pre-populated wiki for the
	moment; copy RecentChanges, UserOptions, SearchPage, HelpPage,
	ZWiki etc. from zwiki.org if you need them.

	* experimental Purple Numbers support for zwiki. A true
	'use_purple_numbers' boolean property on the folder or page will
	cause persistent id numbers (node ids) to be embedded within
	source text and rendered as purple links (after your next page
	edit).  These are usable (with quirks) on (non-DTML) STX pages,
	not yet on RST or WWML or the non-wiki page types.  Performance
	impact when rendering large pages is unknown. Cf
	http://zwiki.org/PurpleNumbers .
	(Mike Mell, Simon Michael, thanks to Eugene Kim & PurpleWiki)

	* fixed a pageWithFuzzyName error in BTreeFolders (IssueNo0535)

	* stxprelinkfitissue and wwmlprelinkfitissue page types weren't
	being auto-upgraded (IssueNo0546)

	* use absolute urls in STX footnotes and comment headings so these
	links work in CMF/Plone (IssueNo0550)

	* use latest page types in new wikis, avoiding excessive
	"non-allowed page type" warnings in edit form (IssueNo0564)

      Skins and content

	* the zwiki product icon was not checked in to CVS as a binary
	file, which may have been causing problems for (even crashing!)
	certain web browsers in the ZMI (Alexander Limi)

	* zwiki_plone: close anchor tags in comment headings to prevent
	bogus hyperlinks in Plone

	* zwiki_plone: initial cut at breadcrumbs-style display of page
	parents (Alexander Limi)

	* zwiki_plone wikipage_footer: don't show the add comment box if
	user doesn't have add comment permission

	* default, zwiki_plone: make the editform's non-allowed page type
	warning show the developer name again, not the end-user name

	* default, zwiki_plone: if a user edits a page again within 24
	hours, re-use their last log note by default (idea: Dean
	Goodmanson)

	* default, zwiki_plone skins: editform code cleanups. The options
	used by the editform template are now 'page', 'text' and 'action'
	as described in the comments.  'id' and 'oldid' options are no
	longer used (but are still provided by Zwiki, for backwards
	compatibility with old templates).

	* zwiki_plone editform rename support: you can now rename a page
	via the edit form. A placeholder page will be left behind and
	links on other pages will be updated if possible (this may need to
	be made more robust).  This ensures Zwiki-compliant page ids,
	makes wiki page renaming possible in plone and makes wiki page
	creation via the CMF/Plone content management interface work
	better.  Also, as a special case, if you are editing the sole page
	in the wiki the page name field will default to "FrontPage", which
	latest Plone will display by default.  To support this, edit() and
	create() now also do a rename if a new name is passed in the
	"title" argument (so named for backwards compatibility).
	(idea: Alexander Limi)

	* zwiki_plone editform: clean up attributes/fix i18n for page type
	radio buttons (fix for IssueNo0549 ?)

	* zwiki_plone editform: in the heading, show whether you're
	editing or creating (Alexander Limi)
	
	* zwiki_plone editform: fix a 0.19 bug which showed the
	originating page's text instead of an empty field when creating a
	page (IssueNo0557)

	* zwiki_plone editform: make editform work with CMF again
	(IssueNo0560)

	* zwiki plone editform: move least-used widgets to the bottom

      Mail and messages

	* comment heading display tweaks - message number no longer
	displayed, date now links to more permanent url based on message
	id, email sender's name is now enclosed in [] to link to personal
	pages

	* citations no longer cause HTML markup to be added to the page
	text
	
	* citations no longer have an extra blank line displayed before
	them

	* smarter paragraph filling in mail-outs: preserve citation
	prefixes and leave indented paragraphs alone

	* like TestPage, a page named 'SandBox' no longer sends mail to
	whole-wiki subscribers

	* display no messages, rather than an error, if unicode gets into
	the page (and document some of the ways this can happen)


Zwiki 0.20.0 2003-07-02

    Summary

        Simpler page types, smarter message handling, auto subscription
        option; mail, skin and miscellaneous bugfixes; python 2.1 or
        greater now required.

    Upgrade notes

        Page types have been simplified and renamed (both the end-user and
        developer names) as mentioned below.  If you have
        standard_page_type or allowed_page_types properties on your wiki
        folders, you should update them to the latest types (in the left
        column below):

        I have dropped python 1.5.2 compatibility as of this release; this
        allows us to use more up-to-date python 2.1 features and means
        zwiki 0.20 and later won't run on very old zope installations.

        The comment method's arguments have changed.
        
    Changes

      General

        * more page type simplifications: 
          As shipped, Zwiki now supports four main wiki page types and
          three non-wiki page types::

           # wiki page types
           'msgstxprelinkfitissuehtml'    :'Structured Text',
           'msgstxprelinkdtmlfitissuehtml':'Structured Text + DTML',
           'msgrstprelinkfitissue'        :'reStructured Text',
           'msgwwmlprelinkfitissue'       :'WikiWikiWeb markup',
           # non-wiki page types
           'html'                         :'HTML',
           'dtmlhtml'                     :'HTML + DTML',
           'plaintext'                    :'Plain text',
        
          The wiki page types have similar features (message formatting,
	  text formatting, wiki linking, pre-rendering, fit tests & issue
	  properties) except for the choice of text formatting rules (and
	  only the STX types allow HTML).

          A wiki will offer a restricted subset of these in the editform:
	  Structured Text, reStructured Text, WikiWikiWeb markup, and HTML
	  by default.  To offer other types, set a custom
	  allowed_page_types lines property on your wiki folder (or change
	  ALLOWED_PAGE_TYPES in Defaults.py).
        
        * new message storage format:
        Comments are now stored as rfc2822-style messages in mbox format
        (think of a wiki page with an mbox stuck on the end).  This looks
        more verbose in the page source, but allows rich message data to
        be stored in a standard way.  Messages must begin with "strict"
        mbox-style 'From ' separators. (If you ever need to add these,
        upgradeMessages may help.)  Messages stored in this way are
        formatted for display with numbers and named anchors
        (#msgN, #msgidXXX, #messages). Message bodies are formatted with
        the usual text formatting rules.  Message-id and in-reply-to
        headers are stored and threads are preserved when posting via
        web. This behaviour has been added to all the main page types, but
        some features require STX mode at present.

        * fix memory leak when printing tracebacks
        (IssueNo0536, Shane Hathaway)

	* clean up '\r\n' line terminators if added by browser, in
	comment().

      Mail

        * fill paragraphs in mailouts, finally. Also wrap at column 70,
        not 78. (IssueNo0340)

        * try to preserve indentation in mailouts somewhat. Each paragraph
        will be re-indented as per it's first line. This means indentation
        within a paragraph will be lost, and a paragraph with only it's
        first line indented will become wholly indented. Hopefully this
        will be better than the old policy of throwing away all
        indentation. (IssueNo0538)

        * prevent duplicates when integrated with a mailing list, by
        excluding the address in the X-BeenThere header from mailout.
        (comment's do_mailout argument replaced with exclude_address)
        (IssueNo0519)

        * a true auto_subscribe folder property will cause any commenters
        to a page to be subscribed there (authenticated/usernamed
        commenters, at least)

	* exclude a page named "TestPage" from whole-wiki subscription.
	Page subscribers will still receive mail from it.

      Tracker

        * supply default categories, severities, statuses lists for the
        issue properties form if they have not been defined. This should
        allow "IssueNoXXXX ..." pages to work in any wiki without
        additional setup.

        * tolerate whitespace in the issue_colours list
        
      Skins and content

        * zwiki_plone: added the last basic elements of the Plone styling,
        cosmetic change to footer, external edit link moved to header.
        (Alexander Limi)

        * skins/zwiki_plone/subscribeform.pt: was a conflict ... I
        manually resolved it... please test (Alan Runyan)

        * zwiki_plone: minor fixes: fix change email address button label,
        remove whitespace from comment form, remove stray code breaking
        editform

        * default: name error when changing email address in
        subscribeform, fixed (IssueNo0537, Laura Trippi)

        * default, zwiki_plone: make editform tolerate an out-of-date
        allowed_page_types property (if allowed_page_types contains type
        that no longer exists, we just list it with the others and rely on
        auto-upgrade to fix the page); also tolerate whitespace there

        * minor xhtml-compliance fixes

        * make skin template error messages more to the point


Zwiki 0.19.0 2003-06-01

    Summary

        Preliminary reStructured Text support, page types cleanup,
        skin bugfixes, customizable issue colours.

    Upgrade notes

        Nothing special this month.

    Changes

      General

        * preliminary reStructured Text support, based on Andreas' and 
        Richard's work.

        * page types cleanup. Retired a bunch of old types, added new ones.
        Fit tests and issue properties form support is now standard.

        * New allowedPageTypes method returns the allowed page types for 
        the wiki, defined in Defaults.py or an allowed_page_types 
        folder lines property. Only these types can be selected when changing
        the page type (except in ZMI). Note: at present a new wiki will not
        allow DTML-enabled types, so if a user edits one of the DTML pages
        like RecentChanges it's type will change, disabling it. The edit form
        gives a warning in this situation.

        * when creating pages, don't inherit page type from the parent - 
        use either the wiki's standard_page_type, the specified type, or 
        the zwiki default. Should make administration simpler.

        * creationTime and lastEditTime now always return a valid DateTime

        * new page methods: ageInDays, lastEditIntervalInDays

        * standard_error_message was getting instantiated as a wiki page in CMF
        (IssueNo0510)

        * fix NameErrors due to missing imports

      Skins and content

        * start with no bookmarks by default

        * UI code cleanups, more useful error messages

        * use xhtml-compliant tag for uploaded images

        * default: replace DTML methods with page templates (IssueNo0508). 
        Zwiki now requires Page Templates.

        * default: XHTML 1.0 compliance fixes for the default skin
        (IssueNo0399, Jordan Carswell)

        * default: subscribeform layout tweaks, remove extra title tag

        * default: fix editform action url

        * default: fix contentspage tal:contents typo

        * default: replace stray DTML in editform with TAL 
        (IssueNo0506, Jordan Carswell)

        * zwiki_plone: remove the bookmarks & help links from the page footer

      Tracker

        * IssueTracker & FilterIssues dtml cleanups, robustness enhancements

        * Instead of highlighting open and pending issues, we now highlight 
        open and pending non-wishlist issues more than 60 days old

        * issue colours code cleanup; issue colours are now defined in 
        Default.py or issue_colours folder lines property


Zwiki 0.18.0 2003-05-01

    Summary

        Full Plone and CMF skin, miscellaneous fixes.

    Upgrade notes

        If you have a cmf_install_zwiki external method, refresh it after
        installing this release (by saving it, or restarting zope).

        The new zwiki_plone skin replaces the zwiki_cmf skin; although the
        latter is still shipped it will hopefully go away soon.  An
        existing CMF zwiki should keep working as before. To change it
        over to the zwiki_plone skin, do this:

         1. in your CMF site's portal_skins Contents tab, delete the
         default and zwiki_cmf folders (and zwiki_orig, if you don't use
         that)

         2. in the properties tab, remove zwiki_cmf (and zwiki_orig) from
         all skins

         3. run the install method again (CMFSITEURL/cmf_install_zwiki)

        Structured text headings will get bigger next time you save the
        page (or visit SOMEPAGEURL/upgradeAll to re-render all pages).
        
    Changes

      General

        * structured text headings now start at H2 not H3

        * when using regulations, don't require change regulations
        permission just to comment (IssueNo0485)

        * be more robust displaying pages with old-style page ids that
        have not yet been upgraded (IssueNo0495)

        * use precise links in contents, rather than depending on
        standard_error_message (IssueNo0454, Leslie Barnes)

        * when saving a page via external editor/ftp/webdav, don't require
        a space after the : in the safety belt/type/log headers. Was
        causing a name error with external editor + emacs whitespace mode
        (IssueNo0438, Andrew Burrow)

        * if there is an id renaming collision during upgradeAll, just log
        the error and continue (IssueNo0483)
        
        * edit conflict & lock dialogs were giving NameErrors

        * new method: ancestorsAsList

      Skins and content

        * a fully functional Plone (and CMF) skin, at last! The
        zwiki_plone skin provides most current features of Zwiki's default
        skin, within the standard plone UI. It should also be functional
        for CMF sites, allowing zwiki_cmf to be retired.  (Alexander Limi
        funded by Walt Ludwick, with Simon Michael, Sidnei da Silva, Alan
        Runyan)

        * skin code fixes; Zwiki accepts Page Templates, Filesystem Page
        Templates, and DTML Methods as skin objects, and will warn if any
        other type is found.

        * UserOptions was not honouring the redirectURL argument if just
        clearing cookies

        * tweaked blank subject comment heading format.. not happy with it
        yet

      Mail

        * mailouts were failing when creating a page with no initial text

        * make comment mailout work when there is no subject_heading field
        (IssueNo0481, az` on irc)

      Tracker

        * when changing issue properties, add a user-supplied or default
        comment to the page recording what was done (DeanGoodmanson)


Zwiki 0.17.0 2003-04-01

    Summary

        Simpler page ids, faster performance and better memory efficiency,
        new general-purpose page type including tracker and fit support,
        more robust parenting, skin improvements, preliminary stylesheet
        support, code cleanups, doctest no longer used.

    Upgrade notes

        If you have pages with punctuation in the names, or zwiki tracker
        issues, you'll need to change their id/name. See below.

        If you have a tracker in your wiki, you'll also need to install
        the latest IssueTracker/FilterIssues pages and add a new 'isIssue'
        FieldIndex to your catalog. Also, in a large wiki you may find
        changing issue descriptions is much slower than before. See below.

        issuedtml and stxprelinkdtmlhtml pages will be auto-upgraded to
        the new stxprelinkdtmlfitissuehtml type.
        
        The CMF install method in Extensions has been renamed to Install.py.
        
    Changes

      General

        * Simpler page ids
 
          Page ids are now always derived from the name (title). This
          improves performance, removes a source of confusion, but means
          pages can no longer have a totally different title and id (like
          tracker issues used to).  Also, page ids no longer include
          punctuation, and fuzzy links now ignore punctuation.

          Pages with old-style ids should be renamed so that wiki links to
          them will work.  You can upgrade these pages and update links
          throughout the wiki by visiting SOMEPAGEURL/upgradeAll.  This
          may take a long time; you can watch progress in the debug
          log. It's safe to run this more than once. Alternately, you can
          visit SOMEPAGE/upgradeId to rename and relink a single page.

          Some incoming links may break due to url changes; having the
          zwiki standard_error_message installed will help.

        * Improved performance and memory efficiency

          Link rendering is faster due to the new ids and code
          refactoring.
          (Unscientific ab test: roughly a 4x speedup rendering a
          normal page and 20x for a long one.)  Also, zwiki is no longer
          so eager to load all pages into the zodb cache. Certain
          operations will still trigger this (search, rename) but in
          general use, a zope serving large wikis should now use less
          memory. This may also help your performance and reduce "first
          page render" delay.

        * new/improved page lookup methods: pages, pageIds, pageNames,
        pageIdsStartingWith, pageNamesStartingWith,
        firstPageIdStartingWith, firstPageNameStartingWith, pageWithId,
        pageWithName, pageWithNameOrId, pageWithFuzzyName. Use these in
        your DTML code when possible as they will be optimized. pageWith*
        now return a correct acquisition wrapper (fixes IssueNo0472).
        pageWithFuzzyName's ignore_case has no extra cost now and is
        always on. The argument is left in place for backwards
        compatibility for the moment. Also this may have been acquiring
        pages, fixed.

        * new general-purpose page type incorporating issue and fit
        support: stxprelinkdtmlfitissuehtml. stxprelinkdtmlhtml and
        issuedtml pages are auto-upgraded to this.  This page type
        displays an issue properties form if the page name begins with
        IssueNo. Also, any tables whose first cell begins with "fit." or
        "fittests." are run as fit tests at page view time.

        * rename improvements: support for upgrading to new-style ids;
        allow renames without sending mail; reduce unnecessary indexing;
        preserve creation info when renaming (IssueNo0398); be more
        tolerant of confused parentage;

        * Don't leave orphans when deleting a page

        * cleaner catalog logging

        * all doctests have been converted to pyunit tests

        * Details of WWML changes in last month's release (PeterMerel):

         - C2-compatible apostrophe embedding using minimal-munch

         - C2-compatible generation of indents from leading spaces

         - Intuitive fixed-width tables using | as a column delimiter. I
           purely hate the STX tables, which do everything except the most
           obvious formatting everybody wants.

         - Ability to use images as page names with [image-url]

         - Ability to generate blockquotes by using = instead of *

         - Ability to force a BR in definitions using \\

         - Probably some other things I've forgotten.
        
      Skins and content

        * the latest zwiki.org RecentChanges: fix a mispaced try which
        allowed errors, be less chatty about brute force/catalog, move
        note field next to page name, drop the "use table" option and the
        T issue indicator.

        * edit form layout improvements

        * lose the gray title background and use site logo on all "form" pages

        * Made the diff form skinnable: support a 'diffform' page template
        or dtml method accepting two arguments: 'revA' and 'difftext'.

        * Made the contents view skinnable: support a 'contentspage' page
        template or dtml method accepting two arguments: 'hierarchy'
        (a html string) and 'singletons' (a list of html strings).

        * allow multiple space-separated wiki names in backlinks' other
        parents field and the page management form (PeterMerel)

        * contents improvements: make "you are here" bold; list singletons
        at the bottom, if any. (PeterMerel)

        * "contents" is used more consistently and is the preferred new name
        for the map method.

        * page creation links now have class "new" (IssueNo0456)

        * preliminary CSS support: the default skin embeds a "stylesheet"
        object if present. 

      Mail

        * longish headings were not being stripped from mailouts

        * mail out comments with their original formatting (not the page
        diff)

        * don't try to find a subject in comment body any more

        * don't send mailouts from a page named TestPage, whether or not it has
        [test] subject; log discarded [test] mailouts

      CMF

        * cmf_install_zwiki.py has been renamed to Install.py (IssueNo0460)

      Tracker

        * Issue pages have a new naming scheme to conform with the new
          page ids: "IssueNoNNNN issue description". upgradeAll will take
          care of this for you. Old IssueNoXXXX urls will still work if
          you have standard_error_message installed. You need updated
          IssueTracker/FilterIssues pages which can be found in
          ZWiki/content/tracker. A new 'isIssue' FieldIndex is required in
          the catalog.

        * changeProperties has been replaced by changeIssueProperties.
          This does a full page rename, with link updating, when changing
          an issue description (slow).

        * The 'issuedtml' page type is deprecated; the new combined
          'stxprelinkdtmlfitissuehtml' type is used instead. Old issue
          pages will be auto-upgraded. See also HowToInstallAZwikiTracker.

        * If you use the new page type throughout, you can change an
          ordinary page into an issue by renaming it "IssueNo..." and vice
          versa.

    Summary

        CMF skin updates, various mail tweaks to support mailing list
        integration, enhancements to comment behaviour, WWML,
        misc. bugfixes.

    Changes

      Skins and content

        * enhancements and fixes to the CMF support and zwiki_cmf skin
        from the nzo project - title fix, wiki folder edit view, don't
        create standard_error_message in CMF, CMF-style edit form, other
        skin updates. (Sidnei da Silva, LaloMartins)

        * dropped zwiki_orig skin
        
        * default skin: subject field, always post with heading,
        tweaked page management form

        * more compact comment headings

        * add discussion icon to comment headings in a CMF site

      Mail

        * mailout all comments, regardless of use_heading flag

        * with multiple bracketed strings in a subject, use the right-most

        * mailin.py: support for preventing duplicates when using a
        mailing list, commented out; 

        * generate list id header from mail_from, not mail_replyto

        * new mail_signature property to override mailout footer

        * new mail_page_name boolean property to disable page name in
        subject

        * mailin.py: parse boolean options correctly

        * don't add extra spaces in mailout subjects

        * log reason for mailout failures

      General

        * WWML: fixed a couple of little bugs and added a couple of little
        extra markups. (PeterMerel)

        * comment(): a non-blank comment subject now enables the heading
        if use_heading is not already true

        * preserve parentage when pages are renamed (IssueNo0168)

        * fixed a strange problem with catalog()

        * fix Localizer ustr NameError caused by non-unicode zope or unit

        subject
        
        * test modules re-organized


Zwiki 0.15.0 2003-02-01

    Summary

        Minor bugfixes and some changes to wikimail behaviour.

    Upgrade notes

        If you're doing mailin, don't forget to re-save your external
        method after installing this release.

    Changes

      Mail

        * don't store page names in recipient real name. This seems to
        create more confusion than it solves. mailin.py's checkrecipient
        option is now off by default, and the line in Mail.py:sendMailTo()
        which puts the page name in mailouts' reply-to is commented out.

        * don't recognize bare wiki names in mailin subjects - only page
        names enclosed in brackets. Explicit is better than implicit.
        More details on http://zwiki.org/WikiMailDiscussion, please
        comment there if you don't agree with these changes.
        
        * non-headed comments were sending error reports to mail_admin
        if configured

      Skins and content

        * default: some fixes for valid HTML (Pieter Biemond, IssueNo0399)

        * default, zwiki_orig: increase max quote size in header to 300

        * zwiki_orig: get rid of the javascript double-click

      General

        * leave unknown link titles blank instead of showing "xxx zwiki bug"

        * a comment's subject (explicit from a field or inlined) is now
        used for the transaction log regardless of the use_heading checkbox.
        

Zwiki 0.14.0 2003-01-09

    Summary

        A mailin.py rewrite.

    Upgrade notes

        If you don't use mailin, no need to upgrade.  After installing
        this you'll want to click your external method's save button to
        update it. Note this version of mailin.py drops the special
        virtual host support.

    Changes

      Mail

        * a rewritten mailin.py with tweaked delivery rules and unit
        tests. Fixes IssueNo0376.

        * be more fussy about recognizing a recipient real name as a page
        name
        
        * bracketed free form names in the subject are now also recognized
        (it will use the first bracketed thing found)


Zwiki 0.13.1 2002-12-07

    Summary

        A "bugfix-plus" release, for IssueNo0385 (missing permissions).

    Changes

        * finish the switch to modern security declarations,
        fixing IssueNo0385 and hopefully not breaking much else.

        * also send mailouts on page deletion and renaming

Zwiki 0.13.0 2002-12-01

    Summary

        Bugfixes, more solid CMF & Plone support, wikimail enhancements,
        skins re-organization.

    Upgrade notes

        If you have mailin set up and find replies going to the default
        page instead of the originating page, see IssueNo0376.

    Changes

      CMF

        * rename CMFInstall.py to cmf_install_zwiki.py

        * CMF skin support. zwiki_cmf is a lightweight CMF skin for zwiki;
        zwiki_orig is a CMF skin that looks like zwiki's standard UI

        * fix edit permission in CMF (IssueNo0366)

        * fix a timezones error when in CMF

        * make wiki folder & page management work in cmf/plone

        * catalog lookup changed: look for a CMF portal_catalog;
        look for SITE_CATALOG on page and containing folder only

        * when creating a Wiki Page in CMF, allow the standard_page_type
        folder property to control it's page_type.

        * hide user options when in CMF

      Mail
        
        * look up destination page in the recipient's real name (first); 
        mailouts will encode the source page in the reply-to's real name.
        This should make addressing and replying more natural.

        * allow subject headings in mail and web comments. (To set the subject
        from a web comment, use an initial one-line paragraph that is bold
        (using '** or < b>') and no longer than 100 characters.)
        Subjects are saved as edit log note and vice versa.

        * generate a mailout when pages are created

        * mailin page creation fixes

        * mailin: handle freeform page names

        * mailin: work even when default page is not found, as long as
        there's at least one wiki page in the folder.

        * mailin: add some failure logging

        * look for 'mailin_policy' property instead of 'posting_policy';
        the latter is still supported but deprecated

        * don't use < hr> in comment headings

      Skins and wiki content

        * clean out & reorganize templates and default content under
        skins, content

        * new unified RecentChanges implementation; use SITE_CATALOG,
        remove hard-coded zwiki.org

      General
        
        * wiki links to pages with accented names (and freeform names in
        general if standard_error_message is not present ?) were not working

        * parent wiki links were generating an error

        * workaround for zope 2.6 stx+dtml breakage (IssueNo0270)

        * fix for "some permissions had errors" (IssueNo0358)

        * fix title changing in ZMI Edit tab (IssueNo0280)

        * increase the added and removed lines truncation limits for diffs
        and mailouts (to 200 and 20 lines respectively)

        * ZWikiPage class initialization fix; fixes an event log file
        warning (and.. ?)

        * auto-upgrade WikiForNow pages

        * log messages at BLATHER priority instead of DEBUG, and don't
        require the Z_DEBUG_MODE or ZWIKI_DEBUG variable any more

        
Zwiki 0.12.0 2002-11-01

    Changes

        * subscription now accepts CMF member usernames as well as email
        addresses

        * add zwiki web, add zwiki page forms internationalized;
        .po files & spanish translation updated (JuanDavidIbanez)

        * preliminary fit (framework for interactive testing) support
        ('dtmlfithtml' & 'stxdtmlfithtml' page types)

        * allow a 'mail_subject_prefix' folder property to override the
        folder title for mailout subjects. Useful when mailout subject and
        cmf's "you are here" must differ.

        * self.ZopeTime didn't work on a page in a CMF site, now does

        * apply the stx initial-word-becomes-bullet workaround for all
        zope versions

        * support for auto-upgrading wikifornow pages

        * minor default ui & content tweaks

Zwiki 0.11.0 2002-10-01

    Summary

        Bugfixes, international page names, edit log notes, WikiForNow
        assimilation completed, CMFWiki integration (alpha).

    Upgrading notes

        See Regexps.py for notes on configuring international page names.
        When running large & extensively cataloged wikis, you might notice
        this version being more memory intensive than 0.10 (which itself
        may be more memory hungry than 0.9.9). This release should coexist
        with CMFWiki without problems.  Otherwise the usual, see
        http://zwiki.org/TenMinuteZwikiUpgradeGuide &
        http://zwiki.org/HowToUpgradeZwiki for more.
        
    Changes (by category)

      Misc

        page names & ids; enable out of the box, with or without a locale
        set up (IssueNo0257)

        * merge CMF support into standard ZWiki pages. See
        Extensions/CMFInstall.py. (alpha)
        (CMFWiki) (ChrisMcDonough)

        * locking fixes for external editor support (CaseyDuncan)

        * save an optional log note with edit (or type change, file
        upload, ftp PUT, page creation, deletion (via DeleteMe))
        (WikiForNow) (KenManheimer)
        
        * allow page type to be set via FTP (WikiForNow)
        
        * Don't allow completely anonymous invocations of rename/delete
        (IssueNo0235)

        * reindex after renaming

        * set "FTP access" permission, send manage_edit through wiki
        editing code the way WikiForNow does (IssueNo0243)

        * a couple of compatibility tweaks for running inside a CMF/plone
        instance - provide view & SearchableText methods, use
        portal_catalog if present, don't use rule in comment headings.

      Default UI & wiki content

        * custom wikipage template was being called with the wrong context
        (IssueNo0225)

        * custom standard_wiki_header/footer methods were being ignored
        (IssueNo0228)

        * provide a traceback in html source when header or footer
        rendering fails

        * standard_error_message: fix missing "; make it work when not in
        site's root folder (IssueNo0250)

        * editform: move options down a row to handle long page names
        better; fix tab ordering

        * display last log note in history link title in header and at top
        left when diff browsing; use a form button to return from diff
        browsing

      Rendering

        * new "text + links" page type

        * wwml: some rendering fixes and convert spaces to tabs, described

        * enable stx bullet workaround for all zope versions (IssueNo0273)
        
      Editing

      Mail

        * filter blank items from mailout recipients (IssueNo0221)

Zwiki 0.10.0 2002-09-01

    Changes

        * minor text cleanups in default editform & zwikidotorg content

Zwiki 0.10.0rc1 2002-08-25

    Summary

        Pre-rendering for better performance, new freeform page names and
        fuzzy linking, WikiForNow regulations support (beta), page
        renaming & deleting, UI enhancement & simplification, better
        upgradability, page templates support, i18n started, many bugfixes
        & minor enhancements.

    Upgrading notes

        This release has renamed page types and a new render-caching
        mechanism, to which pages are upgraded automatically; full-featured
        UI defaults which will be used if you delete your custom DTML
        methods; and one new and one renamed permission.
        See http://zwiki.org/TenMinuteZwikiUpgradeGuide &
        http://zwiki.org/HowToUpgradeZwiki for more.
        
    Changes (by category)

      Default UI

        * made built-in defaults full-featured (equivalent to current
        zwiki.org UI). 

        * when adding a zwiki web, don't instantiate dtml methods, rely on
        the built-in defaults instead

        * support page templates as well as dtml methods for editform,
        subscribeform, backlinks and for main page layout (a page template
        named wikipage will take precedence over standard_wiki_header &
        standard_wiki_footer dtml methods). The page body is passed to in
        wikipage as options/body.  The following additional options are
        passed to editform: page, text, action, id, oldid.

        * built-in defaults are now read from the filesystem.  Defaults
        for standard_wiki_header/standard_wiki_footer are still provided
        but no longer quite as up-to-date and probably will be deprecated.

        * consistent api for accessing UI methods/templates/defaults

        * many UI updates and simplifications in default page layout,
        editform, backlinks etc.; made UI options more flexible & robust

        * full/simple/minimal display modes; simple (no page hierarchy) is
        displayed by default

        * retired jumpsearch (make the search box always do a simple
        search)

        * added tooltips & access keys to most links & form elements

        * display a convenient page rename/reparent/delete form in the
        footer in full mode if the user has a username (and permissions)

        * external editor support

        * make backlinks dtml more robust (IssueNo0210); fixed a case
        where the parent checkbox didn't show up; now uses a catalog if
        available to provide accurate fuzzy backlinks

        * upload permission was incorrect in editform (IssueNo0178)

        * removed "Show advanced edit form" option

        * ensure comment form depends solely on Add comments permission

        * fix white space in center of footer in NS 4.7

        * don't show "sp" for spacer image in text-mode browsers

        * a missing slash caused edits to fail in netscape 4.7

        * added secret AnnoyingQuote edit link

        * better support for web robots - removed robot-excluding meta tag
        from standard_wiki_header/wikipage, added robot exclusion tag to
        editform/subscribeform/backlinks; use form buttons instead of
        links to keep robots out of page history etc.

      Default zwikidotorg content

        * fewer pages

        * new FrontPage

        * new HelpPage

        * updated RecentChanges, uses catalog if available

        * updated SearchPage with selected extra search tools

        * cleaned up UserOptions

        * provide a list of timezones, MoinMoin style
        (IssueNo00146)

        * a standard_error_message method handles nonexistent urls,
        with fuzzy and partial matching on page names

      Rendering

        * Pre-rendering support: new page types (used by default) process
        text formatting rules and wiki linking rules once at edit time.
        This makes rendering of large pages much faster (possibly at the
        expense of quicker zodb growth). Also allows us to accurately
        catalog links.

        * Better freeform page names - square brackets now allow almost
        any page name, not just those with url- and zope-id-safe
        characters. Freeform names are converted to wikiname-like page ids
        and either may be used for linking, supporting co-existence of
        freeform and wikiname pages.

        * Fuzzy linking - square brackets also do fuzzy linking, ignoring
        whitespace and capitalization.

        * square brackets now link only to zwiki pages, not other zope
        objects or url paths

        * Wiki links now have title attributes/tooltips displaying the
        target's age and last editor when you mouse over (except for
        freeform page names in contents hierarchy and parent context)

        can be acquired from the parent folder (or above) and are
        displayed with ../ prepended

        or the content of html anchor tags (IssueNo0194)

        * allow stx tables to have + at the corners

        * the RemoteWikiURL tag is now case-insensitive

        * make accidental structured text footnote processing less likely;

        * don't treat a bare url followed by : as a remote wiki link

        * make stx links work in non-html stx modes (IssueNo0193)

        * fix for IssueNo0186 (page rendering fails if it contains a
        freeform link containing unbalanced parentheses)

        * added (?L) to the regexps which use \w or \b to make them
        locale-sensitive. (EdwardKreis, AlexyKhrabrov,
        InternationalCharsInRegexps)
        
        * display "you are here" in page hierarchy

        advertised

        * include standard mailing list headers in mailouts

        * discard all mail that appears to come from a bot, and the common
        "out of office" auto responder replies

        * post comments/create pages using the sender's real name or just the
        username component from their email address, not the full address
        (IssueNo0066, PieterB/SM)

        * fixed a bug in upgradeSubscribers which caused folder properties
        to proliferate

      Tracker

        * added a createIssue method which can replace the AddIssue &
        IssuePrototype pages
        
        * increased title's max length from 100 to 200 when editing issues

        * when rendering the issue form, generate option menus dynamically

        auto-upgrading to be disabled via flag in Defaults.py; 
        new upgradeAll method for batch upgrading & re-rendering

        * removed STletters dependency for older zopes

        * don't pass stx header argument with zope 2.4.0 (IssueNo0152,

        * debug logging of zwiki catalog operations (if Z_DEBUG_MODE or
        ZWIKI_DEBUG variables are true and STUPID_LOG_SEVERITY is <= -200)
        
    API changes (summary)

        * wikimail/editform/subscribeform/backlinks page templates will be
        used in preference to standard_wiki_header/standard_wiki_footer/
        editform/subscribeform/backlinks DTML methods. The page body is
        passed to wikipage as options/body. These options are passed to
        editform: page, text, action, id, oldid.

        * page types renamed. Here is the current list of page types (see
        AllAboutPageTypes for details)::

          html
          plaintext

        * the RemoteWikiURL tag is case-insensitive

        * the OFS.ObjectManager.bad_id definition is used as the basis for
        generating page ids

        * some properties are now looked up by containment rather than
        acquisition context, eg subscriber lists

Zwiki 0.9.9rc1 2002-04-08

      Features

        - zwiki permissions renamed. Details::

          'Add ZWiki Pages' (no change)
          'Add ZWiki Webs' (no change)
          'Zwiki: Add comments to pages' (was Append to ZWiki Pages)
          'Zwiki: Change page types' (was Change ZWiki Page Types)
          'Zwiki: Edit pages' (was Change ZWiki Pages)
          'Zwiki: Reparent pages' (was Reparent ZWiki Pages)
          'Zwiki: Recycle pages' (was Send ZWiki Pages to Recycle Bin)
          
          Zwiki also uses zope's 'Add Documents, Images, and Files' (no change)

         Upgrade notes: you'll need to make a note of your zwiki
         permissions settings before upgrading and recreate them after this
         upgrade. You'll find all the new permissions at the bottom of the
         security page, aside from the Add permissions which are
         unchanged. Also you may have dtml which checks for the old
         permissions and needs to be updated. For example, the wiki
         templates refer to the permissions by name in
         standard_wiki_header, standard_wiki_footer and editform.

        - zwiki page 'subscribers' property replaced by 'subscriber_list'
        property; the folder also now exposes this in the ZMI.  Upgrade
        notes: old pages will be upgraded as needed, this will affect
        the last-modified times.

        - new zwiki page properties: 'creator', 'creator_ip', and
        'creation_time'

        - a 'redirectURL' REQUEST attribute can be used to control the
        destination after edit, append or comment.

        - the enclosing [] are displayed prior to page creation

        - relative paths within [] now display in their entirety 
        (instead of just the last component)

        - UI and usability tweaks for the default subscription form;
        other page subscriptions are listed

        - the folder title is now used in html page titles, in mailout
        subjects and before the word "contents" in the page header. The
        old titleprefix method is no longer used.
        
        - wikimail: only comments (made via the "comment" method) are now
        mailed out by default; to mail out all edits as before, set a
        'mailout_policy' folder property to "edits".

        - wikimail: hide mailout recipients (if Lennart Regebro's
        MailHostFix product is installed)

        - wikimail: mailout now requires either a 'mail_from' or
        'mail_replyto' folder property. If 'mail_from' is present, always
        use that for the From: field. Otherwise, show the poster's email
        address or user name. (closes IssueNo0122)
        
        - wikimail: increase wrap margin from 70 to 78 in mailouts

        - wikimail: add X-Zwiki-Version, X-BeenThere & Precedence headers

        - wikimail: basic loop protection - silently discard any incoming
        messages containing X-Zwiki-Version

        - wikimail: mailin can now create pages (JosYule)

        - wikimail: mailin can create tracker issues (see mailin.py)

        - wikimail: mailin.py now accepts mail only from subscribers
        (somewhere in the wiki) by default.  Call with 'subscribersonly=0'
        or set folder property 'posting_policy' to "open" to disable.

        - wikimail: the default destination page for mailin can be
        configured with a 'default_page' folder property

        - wikimail: use only the first plaintext part from multipart MIME
        messages

        - wikimail: use virtual host monster to help direct messages if
        present (may have some imeme-isms ?)

        - wikimail: some other tweaks to mailin delivery rules intended
        to simplify mailin alias setup (see mailin.py)

        - zwikidotorg template: header/footer/editform UI updates; display
        subscriber count in the header; set comment headings on by default
        for pages named "IssueNo*"

        - zwikidotorg template: for site logo, use the folder's
        'site_logo' property/object or the default zwiki icon.

        - add zwiki web form: made this a little more robust; added
        support for template configuration wizards (if a form or script
        named TEMPLATE_config is found, redirect there to create the wiki)


      Bug fixes

        - DeleteMe should redirect to the first existing parent
        afterwards, now working again (IssueNo0008)

        - zwiki now coexists with structured text footnote references
        (yay!). [] will link to a matching footnote if there is one,
        otherwise it is treated as a wiki link (IssueNo0110)
        
        - don't treat [] as wiki links if they contain characters which
        zope does not allow in object ids (IssueNo0090)

        - don't html-quote international characters any more. If losing
        international characters due to edits by dumb browsers is now a
        problem for you, please follow up on IssueNo0004.
        (Taewook Kang & others)

        - make wikiname regular expressions a bit more international by
        using string.upper/lowercase. You may need to modify bad_id in
        zope's OFS/ObjectManager.py also.
        (LaloMartins, Alexy Khrabrov)

        - fix for IssueNo0112, structured text pages have extra html &
        body tags (natesain)

        - parenting tweaked to work better with acquisition/subfolders
        (IssueNo0108) (robert@redcor.ch) 
        
        - wikimail: stray html tags were being left in mailouts containing
        long quoted lines (IssueNo0087)

        - wikimail: don't add extra blank lines in mailouts
        
        - wikimail: don't send duplicates when subscribed to both page and
        wiki (IssueNo0055)

        - wikimail: calling mailin in the context of a page should always
        use that page for posting, now it does

        - wikimail: format quoted replies in mailed-in tracker issues,
        as is done with mailed-in comments (IssueNo0070)

        - zwikidotorg template & general: edit access control ui
        improvements.  Help/subscribe links now always visible;
        edit/append links conditionally visible; viewing editform requires
        edit permission; misc. color & layout tweaks.
        
        - zwikidotorg template: fix scrolling to bottom of page after
        comment

        - zwikidotorg template: don't include "set" links on backlinks,
        because they are vulnerable to robots

        - zwikidotorg template: show search and quote in header by default
        again

        - zwikidotorg template: removed the "preferred front page" option
        (IssueNo0120)

        - zwikidotorg template: adding an empty comment was giving an error
        (IssueNo0123)

        - tracker support: issuedtml page type: layout & colour scheme tweaks

        - tracker support: allow sorting by category/severity/status to
        give the expected order (see IssueNo0115)
        
        - tracker support: don't list other page types when editing an issue page

        - tracker support: don't inherit issuedtml page type when creating
        a new page from an issue page

        - Possibly fixed a bug with Add Zwiki Page permission. 

        - unit tests overhauled, cleaned out and updated. Zwiki now
        follows the latest zope testing practices. 

      API changes (summary)

        - permissions renamed (see above)
        
        - viewing editform() now requires edit permission

        - new optional folder properties: 'mail_replyto',
        'posting_policy', 'default_page'
        
        - 'titleprefix' property/method no longer used, folder title used
        instead

        - new optional REQUEST attribute: 'redirectURL'

        - sendMailTo() now takes a list of recipients, not a string

        - subscriberList(), wikiSubscriberList(), allSubscribers() now
        return a list
        
        - new page methods: allSubscriptionsFor(email),
        otherPageSubscriptionsFor(email)

        - zwikidotorg template: new optional folder property 'site_logo'

        - tracker support: new page methods: category_index(),
        severity_index(), status_index()
        
Zwiki 0.9.8 2001-11-29

        - auto-cataloging no longer requires DTMLDocumentExt and adding a
        zwiki page no longer gives "AttributeError: index_object" if it's
        not present. (IssueNo0054). Zwiki uses the catalog specified by
        the SITE_CATALOG property, or "Catalog", or none.

        - the add zwiki web form complained "list.remove(x): x not in list"
        due to missing ZWiki/wikis/DEFAULTS, fixed  (IssueNo0043)

        - includes the experimental 'issuedtml' render method used by
        ZwikiTracker

        - zwikidotorg template: UserOptions was not displaying the
        username field properly

        - a somewhat important change that also went in last release:
        responsibility for generating the page header and footer
        has been moved into the render_* methods


Zwiki 0.9.7.2 2001-11-26

        - blank extra revision on each edit fixed; browsing diffs now
        works like it's supposed to (credits-to: Geoff Gardiner)
        
        - included TextFormatter.py in tarball

        - updated README, removed mention of zwikiwebs.zexp

        - added download link to announcements

        (credits-to: Ray Lance, Dietmar Gaffling)


Zwiki 0.9.7.1 2001-11-23

        - zwikidotorg template: remove "BookMarks" page reference from
        footer

        - ack it's going to be one of *those* releases :)
        zwikidotorg template: UserOptions page_type should be 
        structuredtextdtml


Zwiki 0.9.7 2001-11-23

        - another zwikiwebs change. The 'Add ZWiki Web' form now looks
        for wiki templates in both the filesystem (.../ZWiki/wikis/) and
        the ZODB (/Control_Panel/Products/ZWiki/), with filesystem taking
        precedence. The zwikidotorg template is shipped (via filesystem)
        as the default; additional templates can be installed in either
        place, or not, at user discretion.  Auto-import of zexp's has been
        disabled. (credits-to: CMFWiki)

        - new comment method added, just like append but convenient for
        adding standard comment headings
        
        - misc wikimail & comment heading tweaks; mail-outs now discard
        the comment heading if present; don't display fractional seconds
        in comment headings (credits-to: 1Jerry)

        - stopped antidecapitationkludge appearing in html source; no
        longer used in 2.4

        - misc 2.4 compatibility updates; added workaround to disable
        stxNG's footnote links on 2.4
        
        - zwikidotorg template: UserOptions cleanup; added workaround for
        zope 2.4.x-2.4.2's stx underline problem; added site logo option &
        presets
        
        - automatic cataloging is supported again. Currently, the
        DTMLDocumentExt product is assumed to be present. It's
        SITE_CATALOG property is required to activate this.
        (credits-to: DTMLDocumentExt)
        
        - textDiff now reports more localised changes, instead of spraying
        out the whole page; misc diff tweaks & fixes
        (credits-to: ndiff/difflib)

        - long lines are wrapped before diffing, and long diff chunks are
        abbreviated, for better readability in email. Currently it
        displays up to 10 deleted lines and up to 50 added lines.
        (credits-to: Hamish Lawson's TextFormatter)

        - lasttext and the diff methods accept one or more revision arguments
        (counted backwards from the latest revision).

        - the old html-format diff has been demoted to oldDiff. The new one
        colourizes textDiff's output and adds whizzy navigation links for
        stepping through the edits. (Click on the page timestamp).

        - zwikidotorg template: automatic comment headings now available
        on all pages and enabled by default on *Discussion pages; 
        horizontal rules now used
        
        - zwikidotorg template: header & footer tweaks; don't display 
        ip address for last editor

        - zwikidotorg template: subscribe form email address integrated
        with UserOptions

        - improved default subscribe form's layout; remember email address
        via cookie if possible

        - zwikidotorg template updated to latest zwiki.org layout,
        example append_with_heading method added

        - mail subscribers now receive edits as well as appends

        - simple create method added to api

        - new page- & wiki-wide mail subscription mechanism
        (.../subscribeform)     

        - wiki_page_url/wiki_base_url renamed to page_url/wiki_url;
        checkEditTimeStamp/editTimestamp renamed to
        checkEditConflict/timeStamp; old api kept for backwards
        compatibility

        - code cleanups, refactoring


Zwiki 0.9.5 2001-10-13

        - the link to an uploaded file or image used to be !-escaped; this
        is no longer necessary
        
        - file upload now requires "Add Documents, Images and Files"
        permission (was "Add Documents, Files and Images")
        
        - fixed zwiki_username_or_ip() so last editor username is saved again
        
        - moved zwiki web creation into core python product, so the manual
        ZWikiWebs import is no longer needed.  The sample wikis are now
        shipped as individual zexp's in ZWiki/import, and are
        automatically imported to /Control_Panel/Products/ZWiki at product
        startup. (Install your own sample wikis there as
        well). /Control_Panel/Products/ZWikiWebs can be deleted.

        - "add zwiki web" form updates


Zwiki 0.9.4 2001-08-04

        - escaping remote wiki links with ! should now work

        - tests have been completely reorganized and updated

        - added custom __repr__ from CMFWiki
        
        - refactored code into multiple modules, following CMFWiki.
        Encapsulated some functionality in mix-in classes.

        - another stx fixup: a single letter followed by a period is no
        longer mistaken for a numeric bullet
        
        - fix for one of 0.9.3's stx fixups: spurious html comments no
        longer appear in stx examples

        - exposed the "zwiki_username_or_ip" utility method, which given
        REQUEST returns a best guess for username (authenticated user,
        zwiki_username cookie, or ip address)

        - experimental "lasttext" and "diff" methods show the text of a page's
        last revision and a concise diff with the latest

        - bare/noheader/nofooter flags can now also be passed as keyword args

        - from WikiForNow: wiki-linking is now inhibited within 
        - <pre></pre>
        - <code></code>
        - structured text :: examples
        - structured text '' quoted code
        - html tags.
        
        - append permission now works

        - tweaked the anti-javascript hack

        - tweaked the anti-decapitation kludge

        - added plainhtmldtml mode (DTML + HTML, nothing else)


Zwiki 0.9.3 2001-05-02

        - creating/editing/deleting pages with eg spaces in the name has
        been broken for a while, it seems - made some fixes in this area
        
        - made the edit conflict message more helpful

        - relaxed edit conflict checking: if your username & ip address
        match the last editor's, the timestamp will be ignored.  In other
        words, you can no longer have an edit conflict with yourself.
        This means eg you can backtrack in your browser, edit and click
        Change again. This change may disable conflict checking amongst
        anonymous users coming through a proxy.

        - renamed the "username" property to "last_editor", added
        "last_editor_ip", made these read-only in the mgmt. interface.
        Existing zwiki pages are upgraded when viewed. &dtml-username; is
        still supported for backwards compatibility, but deprecated;
        use &dtml-last_editor_or_ip; by preference.

        - stx workaround: trailing blank lines no longer cause unwanted
        headings

        - stx workaround: initial word plus period no longer becomes a
        numeric bullet

        - stx workaround: whitespace after :: no longer prevents example
        formatting
        
        - stx headings on first lines were broken - fixed
        
        - fix for a 0.9.1 bug: with hierarchy display enabled, creating a
        new page from a top-level page gave "typeerror"

        - gopher: urls are now recognized

        - renamed {wiki,page}_path to {wiki,page}_url in 0.9.2

        are supported but deprecated

        - made remotewikilinks more careful to avoid trailing punctuation

        - allow []-named pages in remote wiki links

        - disable structured text's [] footnote linking to avoid conflicts

        - removed a spurious menu from the add zwiki web form   

        - added UserOptions to the default BookMarks and removed it from
        the page footer

          bookmarks and wikiwikiweb-style username (help from Phil Armstrong)

        - ZWiki is now zope 2.2-compatible (Garth Kidd) and -requiring,
          and benefits from the 2.2 security model. Executable dtml pages
          now run with those permissions that are common to both the
          page-viewing user and the wiki web's owner. Set the folder's

        - bracketed numbers are no longer wikilinks, so StructuredText's 
          footnotes can work


Zwiki 0.3 1999-11-14

        - sample wiki: included latest DTML features from ZWikiWeb - 
          SearchPage, JumpTo, AnnoyingQuote, separate edit page, etc etc.
