Trac 0.11.7 has been released today. It contains one security fix and a few bug fixes and performance improvements.
I know I've written this before, but this is really going to be the last release in the 0.11.x series.
The first 0.12 beta should be pretty close, with (currently) 14 remaining issues. t.e.o has been running
trunk for quite some time, and it's been really stable. I have upgraded my own Trac instances recently, and I wouldn't want to go back! The multi-repository support is especially great, and I have been able to consolidate my Subversion repository and all my Mercurial repositories in a single Trac instance. Automatic preview of ticket comments and wiki pages (the latter with side-by-side display) are also extremely useful. Needless to say, I can't wait to release 0.12 for good!
