This is a new Beta development release, fixing recently discovered bugs.
This Beta release, as any other pre-production release, should not be installed on production level systems or systems with critical data. It is good practice to back up your data before installing any new version of software. Although MySQL has worked very hard to ensure a high level of quality, protect your data by making a backup as you would for any software beta release. Please refer to our bug database at http://bugs.mysql.com/ for more details about the individual bugs fixed in this version.
This section documents all changes and bug fixes that have been applied since the last official MySQL release. If you would like to receive more fine-grained and personalized update alerts about fixes that are relevant to the version and features you use, please consider subscribing to MySQL Enterprise (a commercial MySQL offering).

Functionality Added or Changed
NDB storage engine now supports
CREATE TABLE statements of
arbitrary length. (Previously,
TABLE statements for MySQL Cluster tables could
contain a maximum of 4096 characters only.)
--nowait-nodes startup option for
ndbd, making it possible to skip specified
nodes without waiting for them to start when starting the
cluster. See ndbd — The MySQL Cluster Data Node Daemon.
mysqld_safe no longer checks for a
mysqld-max binary. Instead,
mysqld_safe nows checks only for the standard
mysqld server unless another server binary is
specified explicitly using
--mysqld-version. If you
previously relied on the implicit invocation of
mysqld-max, you should use an appropriate
For partitioned tables, the output of
TABLE STATUS now shows in the
Engine column the name of the storage engine
used by all partitions for the table; in the
Create_options column, the output now shows
partitioned for a partitioned table. This
change also affects the values shown in the corresponding
columns of the
SHOW PLUGIN was renamed to
PLUGIN now is deprecated and generates a warning.
Large file support was re-enabled for the MySQL server binary for the AIX 5.2 platform. (Bug #13571)
Binary MySQL distributions now include a mysqld-max server, in addition to the usual mysqld optimized server and the mysqld-debug debugging server.
Invalid arguments to
DATE_FORMAT() caused a server
crash. Thanks to Jean-David Maillefer for discovering and
reporting this problem to the Debian project and to Christian
Hammers from the Debian Team for notifying us of it.
(Bug #20729, CVE-2006-3469)
MySQL Cluster: An uninitialized internal variable could lead to unexpected results. (Bug #18831)
TRUNCATE TABLE did not reset the
AUTO_INCREMENT counter for
MyISAM tables when issued inside a stored

mysql_reconnect() sent a
NAMES statement to the server, even for pre-4.1
servers that do not understand the statement.
A query against a partitioned table using
incorrect results given the following conditions:
col IS NULL
The table had partitions and subpartitions
The partitioning function depended on a single column
col of one of the MySQL integer
The partitioning function was not monotonically increasing
The same issue could cause the server to crash when run in debug mode. (Bug #18659)
Partition pruning did not work properly for some kinds of
partitioning and subpartitioning, with certain
WHERE clauses. (Partitions and subpartitions
that should have been marked as used were not so marked.) The
error could manifest as incorrect content in
PARTITIONS output as well as missing rows in the
results of affected queries.
Building the server using
--with-example-storage-engine failed to enable
EXAMPLE storage engine in the server.
InnoDB encountered a
ER_LOCK_TABLE_FULL error and
rolled back a transaction, the transaction was still written to
the binary log.
Complex queries with nested joins could cause a server crash. (Bug #18279)
COUNT(*) on a
MyISAM table could return different results
for the base table and a view on the base table.
WHERE ... IS NULL returned
incorrect results from partitioned tables.
Partition pruning did not perform correctly with partitions on
NULL, and could potentially crash the server.
MEDIUMINT columns were not
handled in the same way as other column types by partition
Partition pruning would sometimes use inappropriate columns in performing queries.
Both of these issues were rectified as part of the same bug fix. (Bug #18025)
For tables created in a MySQL 4.1 installation upgraded to MySQL 5.0 and up, multiple-table updates could update only the first matching row. (Bug #16281)
For mysql.server, if the
basedir option was specified after
datadir in an option file, the setting for
datadir was ignored and assumed to be located
Triggers created in one version of the server could not be dropped after upgrading to a newer version. (Bug #15921)
CAST( for large
double values outside the signed
integer range truncated the result to be within range, but the
result sometimes had the wrong sign, and no warning was
Quoted values could not be used for partition option values. (Bug #13520)
Delimited identifiers could not be used in defining partitions. (Bug #13433)
mysql_config returned incorrect libraries on
The server was always built as though
had been specified.
