Trac 1.0 'Cell' (September 7, 2012)
http://svn.edgewall.org/repos/trac/tags/trac-1.0

Trac 1.0 is a major release adding refreshed user interface and
improved DVCS repository support as the most visible changes.

The following list contains only a few highlights:

- 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 TracHacks 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 TracHacks 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!
