InnoDB Plugin has been upgraded to version
1.0.10. This version is considered of General Availability (GA)
In this release, the
InnoDB Plugin is
included in source and binary distributions, except RHEL3,
RHEL4, SuSE 9 (x86, x86_64, ia64), generic Linux RPM packages,
and any builds produced with the
compiler. It also does not work for FreeBSD 6 and HP-UX or for
Linux on generic ia64.
The mechanism that checks if there is enough space for redo logs
was improved, reducing the chance of encountering this message:
ERROR: the age of the last checkpoint is
x, which exceeds the log group

TABLE statements caused excessive memory use.
When using unique keys on
NULL columns in
row-based replication, the slave sometimes chose the wrong row
when performing an update. This happened because a table having
a unique key on such a column could have multiple rows
NULL for the column used by the
unique key, and the slave merely picked the first row containing
NULL in that column.

because the I/O thread could concurrently access the relay log

which closes and reopens the relay log and, while doing so,
initializes (or re-initializes) its I/O cache. This could cause
problems if some other thread (in this case, the I/O thread) is
accessing it at the same time.
Now the thread performing the

Replication: Two related issues involving temporary tables and transactions were introduced by a fix made in MySQL 5.1.37:
When a temporary table was created or dropped within a
transaction, any failed statement that following the
TEMPORARY TABLE or
TABLE statement triggered a rollback, which caused
the slave to diverge from the master.
TEMPORARY TABLE ... SELECT * FROM ... statement
was executed within a transaction in which only tables using
transactional storage engines were used and the transaction
was rolled back at the end, the changes—including the
creation of the temporary table—were not written to
the binary log.
The current fix restores the correct behavior in both of these cases. (Bug #53560)

CURRENT_USER was used to supply
the name and host of the affected user or of the definer in any
of the statements
ALTER EVENT, the reference to
CURRENT_USER was not expanded
when written to the binary log. This resulted in
CURRENT_USER being expanded to
the user and host of the slave SQL thread on the slave, thus
breaking replication. Now
CURRENT_USER are expanded prior
to being written to the binary log in such cases, so that the
correct user and host are referenced on both the master and the

kernel deadlock on Solaris when there are many active threads.
Other POSIX platforms might also be affected.
make_binary_distribution target to
make could fail on some platforms because the
lines generated were too long for the shell.
The server failed to disregard sort order for some zero-length tuples, leading to an assertion failure. (Bug #54459)
The default value of
myisam_max_extra_sort_file_size could be
higher than the maximum accepted value, leading to warnings upon
the server start.
Inconsistent checking of the relationship between
SHOW statements and
INFORMATION_SCHEMA queries caused such
queries to fail sometimes.

The behavior of the RPM upgrade installation has changed. During
an upgrade installation using the RPM packages, if the MySQL
server is running when the upgrade occurs, the server is
stopped, the upgrade occurs, and server is restarted. If the
server is not already running when the RPM upgrade occurs, the
server is not started at the end of the upgrade. The boot
scripts for MySQL are installed in the appropriate directories
/etc, so the MySQL server will be
restarted automatically at the next machine reboot.
