trac itself always had a quite long release cycle, but this was compensated by a continuous stream of plugin releases. but currently the project seems to fail in some key areas:
- lots of plugins need to be installed which is not particularly appreciated by corporate system administrators.
- not doing the next release: it gets postponed without really finding additional users and people who could fix a bug.
- having kind of a deadlock in the three important areas of "multi-project management", "ticket dependencies" and "time tracking".
especially multi project management, dependencies, and time tracking are the key features of the newsly emerging tracker redmine. also a trac importer helps with the migration away from trac.
for java oriented corporations a java based deployment is also important, which arun gupta did with redmine on glassfish.
