Functionality Added or Changed
On Solaris, mysql_config --libs now includes -R/path/to/library so that libraries can be found at runtime.
Bugs Fixed
InnoDB: A regression introduced by Bug 14329288 would result in a performance degradation when a compressed table does not fit into memory.
InnoDB: The maximum value for innodb_thread_sleep_delay is now 1000000 microseconds. The previous maximum value (4294967295 microseconds on 32-bit and 18446744073709551615 microseconds on 64-bit) was unnecessarily large. Because the maximum value of innodb_thread_sleep_delay is limited by the value set for innodb_adaptive_max_sleep_delay (when set to a non-zero value), the maximum value for innodb_thread_sleep_delay is now the same as the maximum value for innodb_adaptive_max_sleep_delay.
InnoDB: In debug builds, creating a unique index on a binary column, with input data containing duplicate keys, would cause an assertion.
InnoDB: InnoDB would fail to start when innodb_data_file_path specified the data file size in kilobytes by appending K to the size value.
InnoDB: An insert buffer merge would cause an assertion error due to incorrectly handled ownership information for externally stored BLOBs.
InnoDB: Assertion failure in thread thread_num in file ibuf0ibuf.cc line 4080
InnoDB: Failing assertion: rec_get_deleted_flag(rec, page_is_comp(page))
InnoDB: Decreasing the auto_increment_increment value would have no affect on the next auto-increment value.
Replication: The server did not handle correctly the insertion of a row larger than 4 GB when using row-based replication.
Replication: When using row-based replication, an additional auto-increment column on the slave version of a table was not updated correctly; a zero was inserted instead.
Replication: Statements involving the Performance Schema tables should not be written to the binary log, because the content of these tables is applicable only to a given MySQL Server instance, and may differ greatly between different servers in a replication topology. The database administrator should be able to configure (INSERT, UPDATE, or DELETE) or flush (TRUNCATE TABLE) performance schema tables on a single server without affecting others. However, when replicating from a MySQL 5.5 master to a MySQL 5.5 or later slave, warnings about unsafe statements updating Performance Schema tables were elevated to errors. For MySQL 5.6 and later slaves, this prevented the simultaneous use of performance_schema and GTIDs (see Replication with Global Transaction Identifiers, in the MySQL 5.6 Manual).
This fix causes all updates on tables in the performance_schema database to be filtered on the master and not replicated, regardless of the type of logging that is in effect. Prior to this fix, statements using were handled by being marked as unsafe for replication, which caused warnings during execution; the statements were nonetheless written to the binary log, regardless of the logging format in effect.
Existing replication behavior for tables in the INFORMATION_SCHEMA database is not changed by this fix.
For more information, see MySQL Performance Schema.
Compilation failed if MySQL was configured with CFLAGS set to include a -Werror option with an argument.
A shared libmysqld embedded server library was not built on Linux.
While printing the server version, the mysql client did not check for buffer overflow in a string variable.
Contraction information in a collation could be mishandled, resulting in incorrect decisions about whether a character is part of a contraction, and miscalculation of contraction weights.
DROP TRIGGER succeeded even with the read_only system variable enabled.
Updating the Performance Schema setup_instruments table on a replication master caused a slave to exit.
Due to a race condition, it was possible for two threads to end up with the same query ID for different queries.
When run by root, mysqld --help --verbose exited with a nonzero error code after displaying the help message.
MySQL client programs from a Community Edition distribution could not connect using SSL to a MySQL server from an Enterprise Edition. This was due to a difference in certificate handling by yaSSL and OpenSSL (used for Community and Enterprise, respectively). OpenSSL expected a blank certificate to be sent when not all of the --ssl-ca, --ssl-cert, and --ssl-key options were specified, and yaSSL did not do so. To resolve this, yaSSL has been modified to send a blank certificate when an option is missing.
A deadlock error occurring during subquery execution could cause an assertion to be raised.
The Performance Schema stage/sql/Waiting to get readlock instrument is no longer used and has been removed.
For system variables that take a string value, SET statements permitted an unquoted value, but values that contained dots were parsed incorrectly and only part of the value was assigned. For example, SET GLOBAL slow_query_log_file = my_slow.log assigned the value my_slow. Now such values must be quoted or an error occurs.
On Windows, mysql_install_db.pl could be run only from within the bin directory under the installation directory.
* MySQL 5.7 changed audit log file output to a new format that has better compatibility with Oracle Audit Vault. This format has been backported to MySQL 5.5 and it is possible to select either the old or new format using the new audit_log_format system variable, which has permitted values of OLD and NEW (default OLD). For details about each format, see The Audit Log File.
* InnoDB; Partitioning: Following any query on the INFORMATION_SCHEMA.PARTITIONS table, InnoDB index statistics as shown in the output of statements such as SELECT * FROM INFORMATION_SCHEMA.STATISTICS were read from the last partition, instead of from the partition containing the greatest number of rows.
* InnoDB: The row_sel_sec_rec_is_for_clust_rec function would incorrectly prepare to compare a NULL column prefix in a secondary index with a non-NULL column in a clustered index.
* InnoDB: An incorrect purge would occur when rolling back an update to a delete-marked record.
* InnoDB: InnoDB would rename a user-defined foreign key constraint containing the string “_ibfk_” in its name, resulting in a duplicate constraint.
* InnoDB: Rolling back an INSERT after a failed BLOB write would result in an assertion failure. The assertion has been modified to allow NULL BLOB pointers if an error occurs during a BLOB write.
* InnoDB: A regression introduced with the fix for Bug 11762038 would cause InnoDB to raise an incorrect error message. The message stated that, “InnoDB cannot delete/update rows with cascading foreign key constraints that exceed max depth of 20”. The error message would occur when killing connections reading from InnoDB tables that did not have foreign key constraints.
* InnoDB: The documentation incorrectly stated that START TRANSACTION WITH CONSISTENT SNAPSHOT provides a consistent snapshot only if the current isolation level is REPEATABLE READ or SERIALIZABLE. START TRANSACTION WITH CONSISTENT SNAPSHOT only works with REPEATABLE READ. All other isolation levels are ignored. The documentation has been revised and a warning is now generated whenever the WITH CONSISTENT SNAPSHOT clause is ignored.
* InnoDB: The srv_master_thread background thread, which monitors server activity and performs activities such as page flushing when the server is inactive or in a shutdown state, runs on a one second delay loop. srv_master_thread would fail to check if the server is in a shutdown state before sleeping.

Bump PKGREVISION.
* Previously, program options could be specified in full or as any unambiguous prefix. For example, the --compress option could be given to mysqldump as --compr, but not as --comp because the latter is ambiguous. Option prefixes now are deprecated. They can cause problems when new options are implemented for programs. A prefix that is currently unambiguous might become ambiguous in the future. If an unambiguous prefix is given, a warning now occurs to provide feedback. For example:
Warning: Using unique option prefix compr instead of compress is
deprecated and will be removed in a future release. Please use the
full name instead.
Option prefixes are no longer supported in MySQL 5.7; only full options are accepted.
* comp_err now checks to make sure that new errors are not being added to MySQL 5.1 or 5.5 because the set of errors for these series is frozen.
* Bugs Fixed

* mysql_upgrade now verifies that the server version matches the version against which it was compiled, and exits if there is a mismatch. In addiion, a --version-check option permits specifying whether to enable version checking (the default), or disable checking if given as --skip-version-checking.

Like last time, where this caused no complaints.
popular database language in the world. MySQL is a client-server implementation
that consists of a server daemon `mysqld' and many different client
programs/libraries.
The main goals of MySQL are speed and robustness.
The base upon which MySQL is built is a set of routines that have been used in
a highly demanding production environment for many years. While MySQL is still
in development it already offers a rich and highly useful function set.
The official way to pronounce 'MySQL' is 'My Ess Que Ell' (Not MY-SEQUEL).
This package contains the MySQL client programs and libraries.
