-What's new in ZODB3 3.3
-=======================
+What's new in ZODB3 3.3 alpha 1
+===============================
 Release-date: XX-XXX-2003
+
+This release contains a major overhaul of the persistence machinery,
+including some user-visible changes.  The Persistent base class is now
+a new-style class instead of an ExtensionClass.  The change enables
+the use of features like properties with persistent object classes.
+The Persistent base class is now contained in the persistent package.
+
+The Persistence package is included for backwards compatibility.  The
+Persistence package is used by Zope to provide special
+ExtensionClass-compatibility features like a non-C3 MRO and an __of__
+method.  ExtensionClass is not included with this release of ZODB3.
+If you use the Persistence package, it will print a warning and import
+Persistent from persistent.
+
+In short, the new persistent package is recommended for non-Zope
+applications.  The following dotted class names are now preferred over
+earlier names:
+
+- persistent.Persistent
+- persistent.list.PersistentList
+- persistent.mapping.PersistentMapping
+- persistent.TimeStamp
+
+ZODB now supports multi-version concurrency control for storages that
+support multiple revisions.  XXX
 
 Changed the ZEO server and control process to work with a single
 configuration file; this is now the default way to configure these
