This release is primarily a bugfix release; changes of note include:

General user UI
 * Granting rights to new groups no longer requires clicking in textbox
   twice in firefox (#29911)
 * Canonicalize CF values (including dates, IP addresses, and IP ranges)
   before comparing to the database value; this prevents spurious
   "changed from a to a" messages.
 * Quick Create now defaults to the lifecycle's default create status,
   instead of hardcoding "new"

Admin
 * DBD::Pg 3.3.0 conflicts with RT's UTF-8 handling; for this release,
   it has been blacklisted.  If you are using PostgreSQL as your
   database and have DBD::Pg 3.3.0 installed, you will need to download
   and install DBD::Pg 3.2.1 from CPAN.
 * rt-fulltext-indexer now locks, to prevent more than one instance from
   running at once (#17423)
 * Quiet a warning in the logo auto-color-detection.
 * Bump CGI dependency (under perl 5.20 and above, only) to quash
   warnings about CGI.pm's deprecation in core (#29053)
 * For compatibility with RT::Extension::MergeUsers, ensure that
   Shredder checks that a user (possibly resolved from a merged user) is
   valid before attempting to shred them
 * Correctly detect presence of graphviz binary (`dot`), instead of
   libgraph.so, for perl dependency calculation

Developer
 * Tests now pass again using RT_TEST_WEB_HANDLER=inline
 * ->AddCustomFieldValues no longer allows adding repeated values
   (#4553)

Documentation
 * Updated example plugins used in documentation
 * Documentation for ColumnMap
 * Correct a reference to max_allowed_packet in backup documentation
 * Document explicit steps for adding a new status to a lifecycle
