 Compatibility

-ZODB 3.2 is known to work with Python 2.2 2.3.  For best results, we
-recommend using Python 2.3.2 or Python 2.2.3.  Note that 2.2.1 does
-not work.
-
-This version of ZODB can be used with Zope, but you must replace the
-version of ZODB that comes packaged with Zope.  It should be possible,
-for example, to install this code into a Zope 2.6 software home and
-run with Python 2.2.  
-
-The Zope 2.7 release should be compatible with this version of ZODB.
-Note that Zope 2.7 will include ZEO, so this package should only be
-needed to run a ZEO server.
-
-The ZEO server in ZODB 3.2 is partially compatible with ZODB 3.1.  A
-new client can talk to an old server, but a new server can not talk to
-an old client.  If you want to upgrade without shutting down all
-components, you should upgrade all of the clients first.  Once all the
-clients are running the new software, you can safely upgrade the server.
