* 1.11.11, 2015-08-25

### BUGFIXES
- The configfile parser now strips whitespace between a configuration
  parameter's value and a trailing comment. Found by Cecil Westerhof.
- The roff manual page sources now render proper hyphens (-), minus characters
  (\-) and en-dashes (\[en]) depending on their context. This is so that
  copying-and-pasting from the manual page works properly.
- The code that checks if the peer is local now properly deals with IPv4
  mapped IPv6 addresses.

==============================================================================
* 1.11.10, 2013-06-11

### BUGFIXES
- Some more format strings that used the 'h' width specifier have been
  changed to remove it, and cast the argument instead, in case we must use
  our snprintf.c replacement.
  Fixes FreeBSD PR#179483 and https://sourceforge.net/p/leafnode/bugs/19/,
  debugged and reported by Alexey Markov.
- The configure.ac updates broke detection of a working snprintf, so that
  the bug above was exposed on many systems.

### CHANGES
- When cross-compiling, leafnode now assumes that the target has a proper
  snprintf implementation, and will not provide its own.

==============================================================================
* 1.11.9, 2013-06-10

### BUGFIXES
- The whoami() function is now IPv6 enabled. Code contributed to openSUSE by
  Boris Manojlovic and submitted by Andreas Stieger, with additional bugfixes
  by Robert Grimm, fixing Debian Bug #667998, reported by Jose Antonio Ortega
  Ruiz <jao@gnu.org>.
- Do not delete news spool on "make uninstall" (which would lose all data),
  but instead only print instructions how the user could do that.
  Reported by Pasi Kallinen, fixes SourceForge bug #3520120.
- The --with-user= now propagates to leafnode.xinetd.
  Inspired by a bug report sent by Ken Robinson.
- When complaining that we are unable to switch the user ID, report the
  current real and effective user IDs to ease debugging.
  Inspired by a bug report sent by Ken Robinson.

### CHANGES
- Leafnode no longer supports PCRE versions before 2.06.
- Leafnode now lets autoconf look for a good sed command, and runs it
  instead of a hard-coded "sed" (first from the $PATH) from "subst".
- Leafnode's subst program (run during build) now runs sed under LC_ALL=C.
  This might fix SourceForge Bug#3575233 reported by Martin Krischik,
  where leafnode failed to compile under macports for MacOS X 10.8.
- Work around compilation failures in ma_sock2name.c due to broken
  IN6_IS_ADDR_V4MAPPED macro on Linux eglibc (Ubuntu 12.04) when
  compiling in strict conformance mode.
- configure.ac updates to avoid autoconf warnings on newer autoconf versions.
- Remove some compiler warnings that were enabled during development, but
  are not terribly useful on code that is not going to change much.

==============================================================================
* 1.11.8, 2010-06-12

### BUGFIXES
- Performance optimization, reported by Gary R. Schmidt.
- Fix a compiler warning on computers where "long" is a wider type than "int",
  such as many 64-bit computers.
- Fix compiler warnings on computers where "long" is a wider type than
  "time_t", such as NetBSD 5.X on 64-bit computers.
- Fix compiler warning "dereferencing type-punned pointer will break
  strict-aliasing rules"
- Fix a file descriptor leak in fetchnews.c's getbody_newno function; reported
  to Debian BTS by Helmut Grohne, fix by Robert Grimm.

### CHANGES
- Leafnode now enables IPv6 support by default. Use --without-ipv6 to disable.
- Leafnode now supports detecting if a peer is in a local network also
  for IPv6 global addresses, providing that the host OS provides getifaddrs().
  This comprises Linux, NetBSD, FreeBSD, but not, for instance, Solaris 10.
  Reported missing by M. G. Berberich.
- Leafnode is now always compiled in maintainer mode.
  This has no impact on run-time behaviour.
- Leafnode now assumes that handlers for signal() do not return a value.

### WORKAROUND
- Skip arbitrary amounts of contiguous CR right before LF. Reported by John R.
  Myers.

### DOCUMENTATION
- Remove the long-obsoleted README.FIRST file.
- The FAQ has information on how to copy the spool.
- FAQ: The MAC OS X two-level namespace documentation for PCRE was removed,
  PCRE is no longer part of the leafnode distribution.
- FAQ: mention how to fix losing unsubscriptions of low-traffic groups in slrn
- config.example: The expire documentation should now be clearer and closer to
  the one in the leafnode(8) manual page. Along the lines discussed by Chris G
  and Whiskers on the leafnode mailing list.

==============================================================================
* 1.11.7, 2009-04-20

### WORKAROUND
- fetchnews: If the LN_SUPPRESS_DATE environment variable is defined and set 
  to any value or empty, fetchnews will not test the upstream server's time by 
  means of the "DATE" NNTP command.
  This can be used to quench related log messages.

### BUGFIXES
- Fix logging if texpire unlinks files without further hardlinks from
  message.id/NNN/
- Fix potential segfault on libcs that do not catch NULL for %s formatting
  (several GNU libc versions do) when trying to retrieve delayed bodies from
  corrupt article headers. Pretend success, to purge article number from
  subscription file.  Bug reported by Chris Carr.
- Fix & change "noactive" so that it can be overridden by "fetchnews -f", as
  documented in config.example.
  Regression as side effect of 1.9.50 fix, reported by Jesse F. Hughes.
- Fix logged IP address in "connected to..., reply:" message when compiled
  without IPv6 support.
  Fixes Mandriva Bug #45605, reported by David W. Hodgins.
- Print connected to... to console as well at proper verbosity level, found
  by maintainer while debugging aforementioned bug.
- Only emit warning that no server with posting permission was found if that's 
  actually needed. Reported by Christian Weiske.
- If corrupted articles had been detected, fetchnews -x NNN would not be able
  to re-fetch the said article because a 0-sized file remained in message.id,
  making fetchnews believe the article was in the spool.
  0-sized message.id/NNN/ files are now purged when checking if the article is
  already in the spool.
  Reported by Peter Bauernfeind. (de.comm.software.newsserver post, May 2008)
- Change interface enumeration to track incompatible NetBSD 5 changes.  The
  latter led to bogus connection refusals in NNTPD.  SourceForge Bug #2700756,
  by Aleksey Cheusov, fix suggested by Roy Marples.
- Add support for SIOCGIFALIAS where available (BSD) in order to obtain
  netmasks for 4.4BSD-style IP aliases.
  getifaddrs() has been suggested as well, but it isn't available everywhere,
  so we would have to keep the old code around anyways, and we can just fix
  that rather than introduce alternative code branches.

### BUGFIXES BACKPORTED FROM LEAFNODE 2
- lsort (used by make update) now detects and report errors.
- "make update" handles the lockfile properly now: it records its PID and
  removes the lock also in cases of failure.
- "make update" restores the old groupinfo file if lsort fails.
- "make update" now builds an up-to-date lsort first.
- "make update" now uses the configured NEWS_USER and _GROUP.
- "make update" is now a phony Makefile target, i. e. it will work even
  if there is a file "update" in the build directory.

### CHANGES
- When creating a Path: header (because the newsreader did not do that), use
  "not-for-mail" instead of NEWS_USER (usually "news") as the user component.
  This seems to resolve propagation issues with 2nd-hop-upstreams, as reported
  in Debian Bug#459980 by Michael Weitzel, with Universität Siegen, Germany.
- When writing to client fails, log decoded errno, too.
  This can help debugging certain firewall misconfigurations more easily.
- Undoing a wordwrap in configure.ac allows for bootstrapping on Cygwin.
- Drop obsolete mysetvbuf().
- leafnode-version now supports an additional "-v" mode to print more
  information on the installation. The output then is similar, but not
  identical - due to different feature sets - to the way leafnode-2 prints it.

### DOCUMENTATION
- Add some comments to UNINSTALL-daemontools
- Put README-FQDN* under leafnode's license. Found to be in conflict with
  Debian's DFSG by Mark Brown.

==============================================================================
* 1.11.6, 2007-03-17

### BUGFIXES
- .site TLDs are refused in FQDN.
- apply patch from Georg Schwarz to fix compilation with SGI IDO cc.
- do not delete articles if the References: lines are malformatted.
  Reported by Adam Funk.
- support autoconf 2.60, fixing datarootdir-related warnings.
- do not log authentication success unless in verbose mode.

### DOCUMENTATION
- fix minor typos in README-FQDN.
- minor changes to INSTALL.

==============================================================================
* 1.11.5, 2006-04-09

### BUGFIXES
- Fix logging of invalid FQDH/FQDN.
- Do not trash delaybody download markers if the interesting.group/* files
  are writeable by NEWS_USER ("news") but owned by somebody else. Found
  debugging a problem described by David Aldred.
- Some syslog messages were still logged at LOG_DEBUG priority without
  debugmode set.
- Support noactive = 0. Reported by Rafal Maj, Debian Bug #329760.
- Support nodesc = 0.
- Keep non-expiring groups (negative groupexpire date) in active file even if
  they have expired upstream. Sourceforge Bug #1230256, Thomas Zajic.
- INSTALL: leafnode needs a "news" group as well. Found by Julien Sansonnens.
- Allow unterminated lines in regular files. Found by Ivo Maintz.
- Applyfilter unfolds headers before matching, to match fetchnews behavior.
- Applyfilter no longer unconditionally removes messages without body
  if delaybody is off. The interesting.groups/group.name file might still
  have pointers so that fetchnews will download the bodies later.

### CHANGES
- "killed nnn (<mess@ge.id>), already fetched before" messages have been
  demoted to debug priority, to avoid syslog spamming with multiple upstream
  servers or after crashes.  Reported by Adam Funk.
- The RPM is now accompanied by a -debuginfo package.
- Build "grouplist" program in "make check".
- The fetchnews manual page states that -f is not to be used in cron jobs.
- The filtering documentation (applyfilter(8) man page and filters.example)
  was overhauled, at the suggestion of Michael R. McCarrey.
  Mike also courteously provided additional filter examples with documentation.

### WEBSITE
- http://www.leafnode.org/ is now served by SourceForge's VHOST service and
  thus serves the same content as http://leafnode.sourceforge.net/

==============================================================================
* 1.11.4, 2005-11-23

### BUGFIXES
- Skip server processing when posting articles fails, for instance,
  because of a protocol error or server disconnect/timeout.
  Bug found when analyzing Debian #318644.
- Do not mark the active for refetch when the failed server has "noread" set
  or fetchnews is in -P (post only) mode. Patch by Brian Sammon.

### COMPATIBILITY CHANGE
- GNU coreutils 5.92 are broken and can no longer create a missing directory
  with "mkdir -p missing/." Work around the bug. Reported by Michael Shigorin.

### DOCUMENTATION
- Switch FAQ.pdf formatting back to XSL stylesheets and RenderX XEP 4.4,
  now that a personal license for OpenSource documentation is available.
- Renamed all CAN-YYYY-NNNN to CVE-YYYY-NNNN in leafnode-SA-*.txt, ChangeLog,
  NEWS and OLDNEWS to chase the CVE database change of 2005-10-19.

==============================================================================
* 1.11.3, 2005-06-08

### SECURITY BUGFIXES
- Fetchnews did not detect timeouts while it was downloading an article
  header, which malicious upstream servers could exploit to mount a denial of
  service attack against the fetchnews client. See leafnode-SA-2005-02.txt.
  CVE Name: CVE-2005-1911

### BUGFIXES
- Bugfix sed expression in makesubst script.  (Reported by Jeff Zacharias.)

### CHANGES
- texpire now tags the message.id expired count with "message.id" rather than
  "total:" to avoid misleading the user who assumes that "total:" would have
  to be the sum of the group counts. See also the FAQ change below.
  SourceForge bug #1215453.
- When debugmode and verbose mode are set, leafnode programs now print a
  warning to stdout that the user should check syslog.conf and the syslog
  output rather than the screen print for debugging and sleeps for three
  seconds.

### DOCUMENTATION
- Add FAQ entry to explain discrepancies between texpire group counts and
  message.id expired articles counts.
- Add FAQ entry to explain influence of Gnus' gnus-read-active-file setting 
  on lost subscriptions, and extend stop fetchnews from unsubscribing FAQ.
  Debian bug #307685.
- Drop FAQ entry on license issues as some parts of leafnode are in fact GPLd.
- Drop FAQ entry on why old articles aren't posted, obsolete since 1.9.33.
- INSTALL and INSTALL_de have been polished.
- Add a hint that syslog.conf must be edited to config.example.
- leafnode(8) mentions that LIST ACTIVE keeps an existing subscription fresh.

==============================================================================
* 1.11.2, 2005-05-04

### SECURITY BUGFIXES
For these two bugs together, the CVE Name is CVE-2005-1453.
For further cross-references, see
<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-1453>
- Fix fetchnews segfault when connection to server dies while fetchnews is
  reading an article body (use-after-free bug).  Regression introduced into
  leafnode v1.9.52.  Denial of service possible, see leafnode-SA-2005-01.txt.
- Fix fetchnews segfault when connection to server dies while fetchnews is
  reading an article header.  Regression in security fix of leafnode v1.9.48.
  Denial of service possible, see leafnode-SA-2005-01.txt

### BUGFIXES
- fetchnews will no longer re-fetch the active file for a server if it has been
  completely received even if fetching articles from this server encounters a
  problem.  Long-standing bug.  Debian bug #70052.
- fetchnews will now properly mark the active for complete re-fetch if it says
  so.  Previously, it forgot the mark in some circumstances.
- A problem fetching the active file or descriptions for a newly added server
  will now mark the active for re-fetch even if articles have successfully
  been retrieved from the same server.

### DOCUMENTATION
- Repair two lines in the German leafnode(8) manual page that became invisible
  as they ran together with a .PP macro.

==============================================================================
* 1.11.1, 2005-04-25

### BUGFIXES
- Fix pluralization bug in "n article[s] posted" message, Debian bug #303157.
- Fix other pluralization bugs.
- Update address of web site in pseudo article, reported by Daniel Zwick.

### PORTABILITY
- Backport leafnode-2 code to prefer /usr/xpg4/bin/id (if present) to
  /usr/bin/id, to improve portability to Solaris and avoid bogus warnings
  during ./configure.

### DOCUMENTATION
- Remove TODO file.
- Update documentation and addresses of mailing lists and web sites,
  there have been obsolete links around in code, pseudo article and
  documentation.
- Add missing IPv6 hints to README files.
- Add incompatibility hint WRT configuration parser to README files.
- Clarify differences between global and server-specific parameters
  in leafnode(8) manual pages.

==============================================================================
* 1.11.0, 2005-03-16

### INCOMPATIBLE BUGFIXES
- fetchnews now supports IPv6 (this causes the version bump to 1.11)
- the configuration parser now supports quoted strings on the right-hand
  side, so that "#" can be used in passwords. See the section
  CONFIGURATION in leafnode(8) for details.

### BUGFIX
- Fix snprintf test that caused leafnode to always use the local
  snprintf rather than the system's. Bug found by Bruno Rohee.
  Regression in leafnode-1.10.7, though with no user-visible effect.

==============================================================================
* 1.10.8, 2005-01-21

### BUGFIX
- Keep interesting groups interesting on LIST ACTIVE and GROUP even if
  they have no articles.  Reported by Brian Sammon.

==============================================================================
* 1.10.7, 2004-11-22

### BUGFIX
- The shipped snprintf function didn't report the proper size for
  literals. It now does. Report by Michael Bäuerle.
- Pull snprintf/vsnprintf replacements from the libc's name space,
  prefixing them with ln_ on linker level. This avoids our overriding
  libc's snprintf/vsnprintf which may cause bogus aborts when other
  parts of the libc (syslog for instance) use formatting characters that
  our minimal vsnprintf implementation does not support.
  Fixes an abort reported by Michael Bäuerle on a system that had
  a non-working snprintf function.

### CHANGE
- The "GROUP.NAME not found in groupinfo file" message will now only
  appear at verbose levels 2 and higher, to avoid uninteresting output
  when a group has just been deleted but is still in interesting.groups.
  Reported by Berthold Höllmann.

### INTERNAL
- The use of the shipped snprintf function for testing purposes can now
  be forced by running: env FORCE_SHIPPED_SNPRINTF=yes ./configure --opts

==============================================================================
* 1.10.6, 2004-09-22

### BUGFIX
- If a server that was configured with "noactive" was unavailable,
  fetchnews would still mark the active file for download. Patch by
  Brian Sammon.

### DOCUMENTATION
- History up to and including 1.9.54 has been split off into an OLDNEWS file.

==============================================================================
* 1.10.5, 2004-08-26

### BUGFIX
- classic delaybodymode (delaybody set, delaybody_in_situ unset) stored
  articles with inaccessible Message-ID file and caused duplicates.
  Reported by Til Schubbe.

==============================================================================
* 1.10.4, 2004-08-15

### CRITICAL BUGFIX
- Only texpire will now delete the message.id/DDD/mids files and only after it
  has the lock, to prevent premature (but reversible) expiry of message.id
  files followed by gazillions of relinks at the next texpire run.
  Bug located and fix tested by Rein Klazes, thanks a lot.

### CHANGES
- Make debug mode logging of texpire a bit more verbose, log the reason why a
  message.id file was unlinked.
- Minor internal cleanups to make the code a bit more efficient, reduced
  memory use in texpire a bit.

==============================================================================
* 1.10.3, 2004-07-28

### BUGFIX
- LIST and LIST ACTIVE reported "empty group" for pseudo groups, rather than
  a group with one article. Reported by Brian Sammon.

### COMPATIBILITY
- Also refresh newsgroup subscription if the newsreader uses LIST ACTIVE
  news.group (when news.group is not a pattern). Suggested by Brian Sammon.

==============================================================================
* 1.10.2, 2004-07-20

### BUGFIX
- Remove old .overview.?????? files from the spool, in order to avoid
  "cannot rmdir(/var/spool/news/group/name): Directory not empty" error.
  Reported by Johannes Berg, Debian Bug #257281.

==============================================================================
* 1.10.1, 2004-06-23

### BUGFIX
- Make sure that the overview (NOV, XOVER) does not cut off the Xref
  information. Regression in leafnode 1.9.50, older versions were fine.
  Reported by Jörg Lüders after a thread in news.software.readers started by
  the pseudonymous SINNER.

### PORTABILITY
- the .spec file now lists BuildPrereq: libpcre.so.0 rather than pcre, to
  become independent of the actual package name, for Mandrake 10.0
  compatibility. Reported and fix tested by Kevin Bulgrien.

==============================================================================
* 1.10.0, 2004-06-10

### INCOMPATIBLE SOURCE-ONLY CHANGE
- PCRE was dropped from the distribution. If it does not come with your
  operating system, you can get it separately from http://www.pcre.org/

### BUGFIXES
- Bugfix: texpire could crash when expiring groups that are on disk but not
  longer in the active file. Reported by Johannes Berg, Debian bug #248824.
- Bugfix: texpire could crash when all-numeric name components were in the
  newsgroup name or in the path. Reported by José María Mateos.
- Bugfix: texpire memory leaks in error handling paths.
- Bugfix: print expiry time for groups that are no longer in the active file.
- Portability: fetchnews aborted on systems with a broken [v]snprintf
  function (such as FreeBSD 4.8 or 5.1) because it used the %p formatting that
  isn't supported by the replacement snprintf that leafnode uses on these
  systems. Fixes FreeBSD PR #67111, reported first by Jeff King.
