fcgi and flup

Trac uses its own private copy of an old version of flup, which works well for basic needs.

More demanding setups may want to use a more recent flup version, notably to benefit from its thread pool.

Now Trac detects and uses the installed version of flup, and only falls back to its own version if flup is not installed.

See #9111 for details


  • This release requires a database upgrade when upgrading from the 0.12.x series:
    trac-admin $TRAC_ENV upgrade
  • PySqlite 1.1.x is no longer supported; use PySqlite 2 (requires version ≥ 2.5.5 or < 2.5.2, see #9434 for details)

Developer-visible changes

A detailed view of the API changes since 0.12.x can be found in TracDev/ApiChanges/1.0.


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 making 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. :-)
