D.1. Changes in release 5.1.x (Development)
The following changelog shows what has been done in the 5.1 tree:
MySQL 5.1 enables table partitioning with a selection of
partitioning algorithms and options available, independently of
the storage engine used by the table. Syntactically, this
implements a number of new extensions to the
ALTER TABLE, and
EXPLAIN ... SELECT statements. See
Chapter 17, Partitioning.
Before MySQL 5.1, the server writes general query log and slow
query log entries to log files. As of MySQL 5.1, the server's
logging capabilities for these logs are more flexible. Log
entries can be written to log files (as before) or to the
tables in the
mysql database. If logging is
enabled, either or both destinations can be selected. The
--log-output option controls the destination or
destinations of log output. See Section 5.11.1, “Server Log Tables”.
MySQL 5.1 implements support for a plugin API that allows the
loading and unloading of components at runtime, without
restarting the server. See Section 27.2, “The MySQL Plugin Interface”.

for each individual 5.1.x release.
