-The major difference between release 3.23 and releases 3.22 and 3.21 is that
-3.23 contains a new ISAM library (MyISAM), which is more tuned for SQL
-than the old ISAM was.
-
-The 3.23 release is under development, and things will be added at a
-fast pace to it.  For the moment we recommend this version only for
-users that desperately need a new feature that is found only in this
-release (like big file support and machine-independent tables).  (Note
-that all new functionality in @strong{MySQL} 3.23 is extensively tested, but as
-this release involves much new code, it's difficult to test everything).
+The 3.23 release has several major new features that are not
+present in the 3.22 or 3.21 releases.  We have added two new
+table types:  MyISAM, a new ISAM library which is tuned for SQL
+and supports large files; and BerkeleyDB which uses the Berkeley
+DB library from Sleepycat Software to implement transaction-safe
+tables.  The 3.23 release also includes support for database
+replication between a master and many slaves.
 
 We are not adding any more new features that are likely to break any
-old code in @strong{MySQL} 3.23 so this version should stabilise pretty soon
-and will soon be declared beta, gamma and release.
+old code in @strong{MySQL} 3.23, so we recommend that you use this
+version.  The replication and BerkeleyDB code is still under development,
+though, so 3.23 is not relesed as a stable version yet.
