trac version 0.10 was released today. it offers a lot of enhancements over the old versions. most importantly new anti-spam hooks. I'm sure there are a lot users eagerly awaiting the new release in portage. thanks.
For the record - copying trac-0.9.6.ebuild to trac-0.10.ebuild then appears to work fine after you emerge it. (You'll need to copy files/0.9.6-postinst-en.txt to 0.10-postinst-en.txt (or remove the lines referencing it from the ebuild) for it to emerge).
In CVS, though it hasn't been widely tested. Please fill new bugs if needed (I have noticed some problems with mod_python, see http://trac.edgewall.org/wiki/TracSubversion#TracandSubversion1.3.1).
