MySQL Reference Manual :: C.4.44 Changements de la version 3.23.17

Fixed a bug in FIND_IN_SET() when the first argument was NULL.

Added table locks to Berkeley DB.

Fixed a bug with LEFT JOIN and ORDER BY where the first table had only one matching row.

Added 4 sample my.cnf example files in the support-files directory.

Fixed duplicated key problem when doing big GROUP BY operations. (This bug was probably introduced in 3.23.15.)

Changed syntax for INNER JOIN to match SQL-99.

Added NATURAL JOIN syntax.

A lot of fixes in the BDB interface.

Added handling of --no-defaults and --defaults-file to safe_mysqld.sh and mysql_install_db.sh.

Fixed bug in reading compressed tables with many threads.

Fixed that USE INDEX works with PRIMARY keys.

Added BEGIN statement to start a transaction in AUTOCOMMIT mode.

Added support for symbolic links for Windows.

Changed protocol to let client know if the server is in AUTOCOMMIT mode and if there is a pending transaction. If there is a pending transaction, the client library will give an error before reconnecting to the server to let the client know that the server did a rollback. The protocol is still backward-compatible with old clients.

KILL now works on a thread that is locked on a 'write' to a dead client.

Fixed memory leak in the replication slave thread.

Added new log-slave-updates option to mysqld, to allow daisy-chaining the slaves.

Fixed compile error on FreeBSD and other systems where pthread_t is not the same as int.

Fixed master shutdown aborting the slave thread.

Fixed a race condition in INSERT DELAYED code when doing ALTER TABLE.

Added deadlock detection sanity checks to INSERT DELAYED.
