Bring Zope info up-to-date in README.txt, and
recommend Python 2.4.2.

Updating this info in PACKAGE.cfg is needed to
build a release tarball.

due to exceeding pool_size available connections, clear its
cache right away.  Because such a connection can never be in
the open state again, hanging on to resources in its cache is
just wasteful.  This was reported as "a problem" on zodb-dev
recently, although it's unclear how the poster got into a state
where it mattered so much.

_setstate():  An MVCC optimization was inadvertently disabled by
fixes for ZClasses.  Repaired.

Elsewhere, repaired English in comments.

Repair typo in exception message.

thread simplifications in Connection._invalidated handling.
Thanks to Florent Guillaume for noticing!

distribution now.  Explain the differences.  Removed the
business about fiddling PYTHONPATH, because it shouldn't
be needed (and isn't for me ;-)).

deprecated in ZODB 3.4.  This should be fun ;-)

method of ZODBDatabase factories.  This gives apps
(like Zopes 2.9 and 3.2) a relatively clean way to
set up their multidatabases.  An earlier checkin
adding an optional new database_name key to
<zodb> sections.

This allows specifying part of what's needed for multidatabases
in a ZODB config file.  More to come.

imported from the Zope3 tests.  Since ZODB doesn't use it,
running the ZODB tests didn't reveal that its testGhostChanged()
got broken (deliberately -- "it's a feature") in ZODB 3.6.
