Bazaar has been backwards-compatible with everything from my
understanding, so any changes they have made to the repository layout
or network protocol they use should not be an issue regardless of what
client or server versions are being used. As for the version number,
the team does monthly releases, so it has nothing to do with stability
and more with their timed release schedule.

As for Mercurial, I have been told their repository layout has not
changed since their first release and updates have been more about bug
fixes and speed improvements.
