+What's new in ZODB3 3.2 beta 2
+==============================
+Release date: 16-Jun-2003
+
+Fixed critical race conditions in ZEO's cache consistency code that
+could cause invalidations to be lost or stale data to be written to
+the cache.  These bugs can lead to data loss or data corruption.
+These bugs are relatively unlikely to be provoked in sites with few
+conflicts, but the possibility of failure existed any time an object
+was loaded and stored concurrently.
+
+Fixed a bug in conflict resolution that failed to ghostify an object
+if it was involved in a conflict.  (This code may be redundant, but it
+has been fixed regardless.)
+
+The ZEO server was fixed so that it does not perform any I/O until all
+of a transactions' invalidations are queued.  If it performs I/O in the
+middle of sending invalidations, it would be possible to overlap a
+load from a client with the invalidation being sent to it.
+
+The ZEO cache now handles invalidations atomically.  This is the same
+sort of bug that is described in the 3.1.2b1 section below, but it
+affects the ZEO cache.
+
+Fixed several serious bugs in fsrecover that caused it to fail
+catastrophically in certain cases because it thought it had found a
+checkpoint (status "c") record when it was in the middle of the file.
+
+Two new features snuck into this beta release.
+
+The ZODB.transact module provides a helper function that converts a
+regular function or method into a transactional one.
+
+The ZEO client cache now supports Adaptable Persistence (APE).  The
+cache used to expect that all OIDs were eight bytes long.
