Trac 0.10.4 (Apr 20, 2007)
http://svn.edgewall.org/repos/trac/tags/trac-0.10.4

 Trac 0.10.4 is a bug fix release. The following list contains only a
 few highlights:

 * Repository cache improvements. The new syncing scheme is incompatible with
   the previous one and requires a database schema upgrade in order to prevent
   the old and the new codebase to be mixed. A repository resync is not needed,
   though. The 0.10.4 scheme is compatible with the 0.11 one.
   (#3837, #4043 and #4586)
 * Fix a possible freeze under heavy load (#4465)
