Release Notes for Trac 0.11 '<codename>'

Note about the '<codename>':
As the most prominent change for 0.11 is the transition from ClearSilver to Genshi, I propose using Genshi. We could possibly reserve this codename for the day we release a Genshi-only Trac, i.e. when the Clearsilver templates will not be supported anymore (0.12?). In that event, the codename could be either 'setuptools' or 'workflow', depending what gets done first ;)

Preliminary Notes - Trac 0.11 is still in heavy development and undergoing a lot of changes…

User visible changes

Time zone support

Each user can select which time zone they want timestamps to be presented in. If pytz is installed a complete list of time zones will be available, otherwise Trac will fall back on a shorter list from an internal time zone implementation.

setuptools is now used for the packaging

TBD. See log:sandbox/setuptools

Improved Syntax Highlighting

Trac can now use the Pygments syntax highlighter out-of-the-box. This is a much nicer syntax highlighter than the one previously supported (SilverCity, Enscript and PHP).

Lots of minor improvements


  • The [trac] base_url setting is now mandatory for generating correct URLs outside the context of a user request.
  • The [trac] templates_dir setting is considered harmful… You probably need to remove that setting when you browse Trac and get the following plain text error:
    TemplateNotFound: Template "error.html" not found

Developer-visible changes

Genshi template engine

Trac now uses the Genshi template engine instead of ClearSilver. Plugins using the latter will still be supported in Trac 0.11, but probably not longer.

datetime everywhere

Trac used to handle time informations as int timestamps. Now we're using datetime objects.

Internal API changes

A detailed view of the API changes since 0.10.x can be found in TracDev/ApiChanges/0.11.


Many thanks to the growing number of people who have, and continue to, support the project. Also our thanks to all people providing feedback and bug reports that helps us make Trac better, easier to use and more effective.

Without your invaluable help, Trac would not evolve. Thank you all.

Finally, we offer hope that Trac will prove itself useful to like-minded programmers around the world, and that this release will prove an improvement over the last version.

Please let us know. :-)
