The main short-term changes are:
1) BOINC now uses subversion for source-code control.
The trunk is now http://boinc.berkeley.edu/svn/trunk/boinc
Use svn co to check it out.
The CVS repository is deprecated. It's still there,
but don't use it. We'll get rid of it soon.
2) BOINCzilla is deprecated.
The bug database is now the one on the BOINC/Trac page.
We're in the process of active bugs from BOINCzilla to BOINC/Trac.
Note: anyone can add or append to bugs in BOINC/Trac; no account needed.
Longer-term, we'll be moving most of the BOINC documention
to Trac's Wiki format, and using the various project-planning
features of Trac.
