To confuse Dovecot versioning even more, I've added "dovecot-stable" module into CVS. This is a version of Dovecot before the recent keyword changes but with several bugfixes backported to it. It's thought to be mostly stable.
I intend to keep it updated with important bugfixes and with other simple bugfixes. Although I'm not sure if I'll make a large code base upgrade once keyword changes are stable.
This is mostly meant for people who _really_ want to use 1.0-test codebase in production right now. Perhaps it's already more stable than 0.99.x, but upgrading should probably be made easier for v1.0.
The dovecot-stable module itself is just a hack that will go away at some point. Once the main codebase is stable enough for v1.0 beta release, I'll make a stable branch instead in the main dovecot module (and probably with different RCS than CVS).
