D.1.1. Changes in MySQL 5.1.60 (16 November 2011)
------------------------------------------------


*Functionality Added or Changed*

* Upgrading from an Advanced GPL RPM package to an Advanced RPM
package did not work. Now on Linux it is possible to use rpm -U
to replace any installed MySQL product by any other of the same
release family. It is not necessary to remove the old produce
with rpm -e first. (Bug #11886309)

* MEMORY table creation time is now available in the CREATE_TIME
column of the INFORMATION_SCHEMA.TABLES table and the Create_time
column of SHOW TABLE STATUS output. (Bug #51655, Bug #11759349)

*Bugs Fixed*

* *InnoDB Storage Engine*: This fix improves the performance of
instrumentation code for InnoDB buffer pool operations. (Bug
#12950803, Bug #62294)

* *InnoDB Storage Engine*: Data from BLOB columns could be lost if
the server crashed at a precise moment when other columns were
being updated in an InnoDB table. (Bug #12704861)

* *InnoDB Storage Engine*: Lookups using secondary indexes could
give incorrect matches under a specific set of conditions. The
conditions involve an index defined on a column prefix, for a
BLOB or other long column stored outside the index page, with a
table using the Barracuda file format. (Bug #12601439)

* *InnoDB Storage Engine*: This fix corrects cases where the MySQL
server could hang or abort with a long semaphore wait message.
(This is a different issue than when these symptoms occurred
during a CHECK TABLE statement.) (Bug #11766591, Bug #59733)

* *Replication*: Issuing the following statements, in the order
shown, could cause a deadlock between the user thread and I/O
thread:

START SLAVE;
STOP SLAVE SQL_THREAD;
START SLAVE;
(Bug #11878104)

See also Bug #44312, Bug #11752963, Bug #38715, Bug #38716.

* Internal conversion of zero to binary and back could yield a
result with incorrect precision. (Bug #12911710)

* Valgrind warnings generated by filesort operations were
fixed. (Bug #12856915)

* Several improvements were made to the libedit library bundled
with MySQL distributions, and that is available for all platforms
that MySQL supports except Windows.

* Navigation keys did not work for UTF-8 input.

* Word navigation and delete operations did not work for UTF-8
input with Cyrillic characters.

* Nonlatin characters were corrupted in overwrite mode for UTF-8
input.

* Long queries caused the statement history file to become
corrupted.

* The Alt key caused history operations to fail.

(Bug #12605400, Bug #12613725, Bug #12618092, Bug #12624155, Bug
#12617651, Bug #12605388)

* The help message for mysql_install_db did not indicate that it
supports the --defaults-file, --defaults-extra-file and
--no-defaults options. (Bug #58898, Bug #11765888)

* An assertion designed to detect zero-length sort keys also was
raised when the entire key set fit in memory. (Bug #58200, Bug
#11765254)

* myisampack could create corrupt FULLTEXT indexes when compressing
tables. (Bug #53646, Bug #11761180)

* OPTIMIZE TABLE could corrupt MyISAM tables if myisam_use_mmap was
enabled. (Bug #49030, Bug #11757032)

* If MySQL was configured with --without-plugin-innobase and
--with-plugin-innodb_plugin, to suppress building the built-in
InnoDB storage engine and build the InnoDB Plugin instead, the
innochecksum utility was not built. (Bug #47337, Bug #11755544)

* A linking problem prevented the FEDERATED storage engine plugin
from loading. (Bug #40942, Bug #11750417)

* On Fedora, certain accesses to /var/lib/mysql/HOSTNAME.err were
blocked by SELinux policy, which made the server fail at startup
with the message: Manager of pid-file quit without updating file
(Bug #37165, Bug #12927740)

* For FEDERATED tables, loss of connection to the remote table
during some insert operations could cause a server crash. (Bug
#34660, Bug #11747970)

D.1.1. Changes in MySQL 5.5.19 (Not yet released)
------------------------------------------------
*Functionality Added or Changed*

* Performance of metadata locking operations on Windows XP systems
was improved by instituting a cache for metadata lock
objects. This permits the server to avoid expensive operations
for creation and destruction of synchronization objects on XP. A
new system variable, metadata_locks_cache_size, permits control
over the size of the cache. The default size is 1024. (Bug
#12695572)

*Bugs Fixed*

* Rounding DBL_MAX returned DBL_MAX, not 'inf'. (Bug #13261955)

* mysql_upgrade did not upgrade the system tables or create the
mysql_upgrade_info file when run with the --write-binlog or
--skip-write-binlog option. (Bug #60223, Bug #11827359)

* If a plugin was uninstalled, thread local variables for plugin
variables of string type with wth PLUGIN_VAR_MEMALLOC flag were
not freed. (Bug #56652, Bug #11763882)

* Deadlock could occur when these four things happened at the same
time: 1) An old dump thread was waiting for the binary log to
grow. 2) The slave server that replicates from the old dump
thread tried to reconnect. During reconnection, the new dump
thread tried to kill the old dump thread. 3) A KILL statement
tried to kill the old dump thread. 4) An INSERT statement caused
a binary log rotation. (Bug #56299, Bug #11763573)
