Hi, See
http://www.cyrius.com/publications/michlmayr-phd.pdf for a dissertation about the role of release management in open source projects. I have not read all of it, but it does contain some interesting thoughts about whether to use feature based releases, or time based releases. Also, it touches on what practices and tools seem to make release processes work better in terms of helping the resulting quality of the release. It should be an interesting read at this point, where plans are being made for the process for 1.6. Regards, Asger
