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”


  • 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


  • Tests now pass again using RT_TEST_WEB_HANDLER=inline
  • ->AddCustomFieldValues no longer allows adding repeated values


  • 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
