• The default theme looks more modern, especially on recent browsers (no effort has been made to make it look better on older browsers like IE6 or 7)
• The [TH:GitPlugin] has been donated by Herbert Valerio Riedel to the Trac project (many thanks!) and is now maintained here as an optional component
• As a consequence, the Subversion support has been moved below tracopt.versioncontrol as well
• The Git and Mercurial log view feature a visualization of the branching structure
• Usability improvements for the tickets, with a better support for conflict detection and resolution
• Integration of the [TH:BatchModifyPlugin], contributed by Brian Meeker (many thanks!) and is now maintained there as a default component
• jQuery/UI integration, featuring a date picker for date fields
• Improved integration with Pygments syntax highlighting
• ... and numerous smaller features added and bugs fixed since 0.12!
