What's New in version 4.4.2
  • checksetup.pl was incorrectly reporting DBI 1.630 (1.63) as being older than 1.614, preventing the upgrade to complete. If you still use Perl 5.10.0 or older, make sure you have the version module installed before running checksetup.pl. If you use Perl 5.10.1 or newer, this module is already available and no special action is required. (Bug 938300)
  • An error about longdescs.comment_id was thrown by MySQL 5.0 and 5.1 when upgrading to Bugzilla 4.4 or 4.4.1. (Bug 870369)
  • Saved searches containing Unicode characters in their name could not be run if Digest::SHA 5.82 or newer is installed. (Bug 964113)
  • A regression in Bugzilla 4.4.1 caused email_in.pl to fail with an "invalid token" error message. (Bug 928331 and bug 930013)
