# Functionality Added or Changed
* CMake now supports a -DTMPDIR=dir_name option to specify the default tmpdir value. If unspecified, the value defaults to P_tmpdir in <stdio.h>. Thanks to Honza Horak for the patch.
# Bugs Fixed
* InnoDB: Table renaming errors would appear in the LATEST FOREIGN KEY ERROR section of the SHOW ENGINE INNODB STATUS output.
* Partitioning: Queries using the index_merge optimization (see Index Merge Optimization) could return invalid results when run against tables that were partitioned by HASH.
* Partitioning: When no partition had returned a row since the last HA_ERR_KEY_NOT_FOUND error, the use of uninitialized memory in the priority queue used for returning rows in sorted order could lead to a crash of the server.
* Replication: mysqlbinlog --verbose failed when it encountered a corrupt row event in the binary log. Such a row event could also cause the slave to fail.
* Replication: When log_warnings is greater than 1, the master prints binary log dump thread information—containing the slave server ID, binary log file name, and binary log position—in mysqld.1.err. A slave server ID greater than 2 billion was printed with a negative value in such cases.
* Replication: Invalid event offsets in the binary log were not always handled correctly, which could lead to replication failure.
* The cache used for the Index Merge access method was freed only after successful retrieval of all rows. Interruption or failure of the operation led to a file descriptor leak.
* For utf8 and utf8mb4 strings, handler functions unnecessarily called a Unicode conversion function.
* Use of a nonmulti-byte algorithm for skipping leading spaces in multi-byte strings could cause a server exit.
* For the utf8_bin collation, ORDER BY LOWER(col_name) could produce incorrect ordering.
* On Windows, the --local-service server option did not work, and was not displayed in the --help message.
* The prototype of the Performance Schema instrumentation API mysql_cond_timedwait() call was fixed to be drop-in compatible with pthread_cond_timedwait(). This fix affects only implementers of third-party plugins.
* For the path specified with the --basedir option, mysql_plugin attempted to unlink the path rather than free the memory in which the path was stored.
* COUNT(DISTINCT) sometimes produced an incorrect result when the last read row contained a NULL value.
* Some scripts displayed out-of-date information regarding where to report bugs.
* Updating a FEDERATED table with UPDATE... JOIN caused a server exit when the local table contained a single row and that row could be joined to a row in the FEDERATED table.
* mysql_install_db referred to the obsolete mysqlbug script for reporting problems.
