Redmine

You can see what's new in this release in the changelog.

This RC release is frozen with Rails 2.0.2 and should be very close to the 0.7 final.
Upgrading from 0.6 can be done as usual with a simple database migration. Migration from 0.6 to 0.7 RC1 then to 0.7 will be of course possible.

It can be downloaded in either .tar.gz or .zip format at Rubyforge.
