Version 6.2 beta
================
- #255911 node_submit() is not necessary for data integrity check.
- Rename date.views.inc and change handling to new Views auto-include method.
- Fix for critical flaw in the new timezone list handling that was creating an invalid array.
- #257874 and #187599 provide a way to generate field content for the devel module.
- Bad typo in date column type.
- Fix install errors.
- #255166 fix copy/paste error in date_token function name.
- Working in a new sql handler class so we can use the same class in both.
- Update date copy to convert either version 1 or version 2 Event nodes.
- Add missing strtotime validation and format help text to textfield date and clarify that it's really a custom input format (which uses strtotime if the custom input fails).
- Change method of getting translations for all timezones into the install file.
- #256079 make translation of abbreviations easier.
- #254930 fix parse error.

- #256078 Fix typo in popup calendar.
- #255739 Fix backwards validation message when testing that the To date is greater than the From date.
- Make sure anonymous users don't see timezone message.
- Prepare for proposed core timezone handling from #11077 by getting rid of deprecated timezones and adding in js timezone name detection.
- Rework default timezone handling to force a valid date even when timezones are not set to get rid of numerous installation and operational errors caused by invalid date objects.
- Update site timezone offset during cron and user offset during login to make sure that modules that rely on the timezone offset  have current information to process when the offset changes.
- #251511 Rename function to avoid clash with Diff module.
- Rework the date filter and argument -- simplify some of the code but still keep as much flexibility as possible. You can set up the filter to provide either a date or offset selector (or both), you can set the granularity of the date parts, and any part can be set to all all values, the current time, or a specific value for either a single date or a from/to combination.
