Dear MySQL users,

MySQL Server 5.6.45, a new version of the popular Open Source
Database Management System, has been released. MySQL 5.6.45 is
recommended for use on production systems.

For an overview of what's new in MySQL 5.6, please see

     Starting with 5.6.11, Microsoft Windows packages for MySQL 5.6
     are available both as a "full" installer and as a "web" installer.
     The full installer is significantly larger and comes bundled with
     the latest software releases available. This bundle makes it easy
     to download and configure a full server and development suite.

     The web installer doesn't come bundled with any actual products
     and instead relies on download-on-demand to fetch only the
     products you choose to install. This makes the initial download
     much smaller but increases install time as the individual products
     will need to be downloaded.

For information on installing MySQL 5.6.45 on new servers or upgrading
to MySQL 5.6.45 from previous MySQL releases, please see

MySQL Server 5.6.45, is available in source and binary form
for a number of platforms from our download pages at

We welcome and appreciate your feedback, bug reports, bug fixes,
patches, etc:

Changes in MySQL 5.6.45 (2019-07-22, General Availability)

Functionality Added or Changed

     * Microsoft Windows: A new warning message now reminds DBAs
       that connections made using the MySQL named pipe on
       Windows has limited the permissions a connector can
       request on the named pipe.
       Previously, the named_pipe_full_access_group system
       variable was set to a value that maps to the built-in
       Windows Everyone group (SID S-1-1-0) by default. However,
       this group is not ideal and should be replaced with a
       group that restricts its membership for connectors that
       are unable to request fewer permissions on the MySQL
       named pipe.
       The new warning is written to the error log at startup if
       the string value assigned to named_pipe_full_access_group
       is '*everyone*' (or the Windows System Language
       equivalent) and named pipes are enabled. In addition, the
       warning is written to the error log and raised to the
       client if the system variable is reset to the Everyone
       group at runtime.

Bugs Fixed

     * InnoDB: A query that scanned the primary key of a table
       did not return the expected result. (Bug #28104394, Bug

     * InnoDB: A full-text cache lock taken when data is
       synchronized was not released if the full-text cache size
       exceeded the full-text cache size limit. (Bug #25289359)

     * InnoDB: Client sessions using different
       auto_increment_increment values while performing
       concurrent insert operations could cause a duplicate key
       error. (Bug #15851528, Bug #67526)
       References: Reverted patches: Bug #14049391, Bug #65225.

     * Replication: In query log events in the binary log, the
       thread ID used for the execution of DROP TABLE and DELETE
       statements was identified incorrectly or not at all. On a
       multi-threaded replication slave, where temporary tables
       were involved (which require the correct thread ID as
       they are session specific), this omission resulted in
       errors when using mysqlbinlog to replay the binary log
       for point-in-time recovery. The thread ID is now set
       correctly. (Bug #28642318, Bug #92398)

     * Installing from RPM packages could result in an error log
       with incorrect permissions. (Bug #29702462)

     * Enabling audit log encryption could cause a server exit.
       (Bug #29549327)

     * MySQL Installer did not install OpenSSL DLL dependencies
       if the Development component was not selected. (Bug
       #29423421, Bug #94168)

     * The parser could leak memory for certain
       multiple-statement queries. (Bug #29419820)

     * MySQL does not support OpenSSL session tickets, but did
       not set the SSL_OP_NO_TICKET flag to inform OpenSSL of
       that. The flag is now set. (Bug #27655493)

     * UpdateXML() did not always free memory properly in
       certain cases. (Bug #27312862)

     * Empty values in the name column of the mysql.plugin
       system table caused the server to exit during startup.
       (Bug #27302459)

     * Some PROXY grants were not replicated to slaves, causing
       incorrect replication. (Bug #23289541, Bug #81424, Bug

     * If an INSTALL PLUGIN statement contained invalid UTF-8
       characters in the shared library name, it caused the
       server to hang (or to raise an assertion in debug
       builds). (Bug #14653594, Bug #23080148, Bug #27167197)
