[Zope-dev] Twice-annual releases and bugfixes?

[Jeff Kowalczyk]

What does the twice-annual release policy say about bugs and/or packaging
errors that are identified and fixed within a very short time of the
official release announcement?

    +* Fix an adapter look-up bug in the local site implementation
    +that was due to an oversight during the port to Zope 3.2.

I'm building from svn, so it doesn't make much difference to me, but I was
curious whether the circumstances (if any) that would trigger bugfix
releases were documented anywhere.
