Dear MySQL users,

A new GA (general availability) version of MySQL Router has
been made available: MySQL Router 2.0.4 GA.

The MySQL Router is a new building block for high availability
solutions. MySQL Router simplifies development of high availability
applications by intelligently routing queries to MySQL Servers
for increased performance, robustness, and uptime.

MySQL Router also connects seamlessly with MySQL Fabric permitting
Fabric to manage the high availability groups for the router,
supporting monitoring and automatic management of MySQL servers
for redundancy and continued operation.

You can download MySQL Router from http://dev.mysql.com/downloads/router.
Package binaries are available for several platforms and also as a
source code download.

If you are a commercial customer, MySQL Router is available via the
MySQL Oracle Support (MOS) website. Packages will be available on
eDelivery at the next monthly refresh.

Documentation for MySQL Router can be found at
http://dev.mysql.com/doc/mysql-router/en/

Enjoy!

Changes in MySQL Router 2.0.4 (2016-11-23, General
Availability)

   Functionality Added or Changed

     * The unused ip_from_addrinfo() function was removed. (Bug
       #22811176)

     * Windows support was added. Binaries are now available for
       download, and several Router command line options were
       added to configure a Windows service for MySQL Router.
       The new command line options on Windows are
       --install-service (service starts automatically),
       --install-service-manual (service can be started
       manually), --remove-service (removes a service), and
       --service (starts a service). The service name is
       MySQLRouter.
       For additional information about these options, see
       Starting the Router
       (http://dev.mysql.com/doc/mysql-router/en/mysql-router-se
        rver-starting.html).

   Bugs Fixed

     * The RPATH for executable and shared libraries did not
       contain both the router library path and the router
       plugin library path. (Bug #24763533)

     * The RPATH was incorrect in the executable for RPM builds.
       The plugin_folder path cannot be set to a value not
       present in the executable, and the paths should be used
       for variable interpolation, not to control where plugins
       are found. The error was similar to "Error:
       mysql_protocol.so: cannot open shared object file: No
       such file or directory".
       Additionally, the INSTALL_LIBDIR was incorrectly used,
       which also resulted in path related errors. (Bug
       #24669798, Bug #24695503)

     * When writing packets read from the sender (client or
       server) to the receiver, if a single write() call did not
       write all requested data, the whole buffer was written in
       another attempt. Now, only the remaining part of the
       buffer gets written. (Bug #24578638)

     * The SO version for libmysqlharness was 0, which is
       usually reserved for pre-release versions. The SO version
       was changed to 1, so the library file name changed from
       libmysqlharness.so.0 to libmysqlharness.so.1. (Bug
       #24557123)

     * On OS X, linking Router to Fabric would fail to function
       by default due to linking problems. (Bug #24527866, Bug
       #80376)

     * The read-write mode (which uses the first-available mode
       schedule) could reconnect to the first listed server
       (destination) after failing to connect to all listed
       servers. Instead, it now always behaves as documented,
       which is to not reconnect after all destinations failed
       to connect. If a reconnection is desired, then use the
       read-only mode instead, which implements the round-robin
       schedule. (Bug #24367453)

     * Backslashes in configuration definitions, such as file
       paths, could escape characters. (Bug #24360999)

     * On OS X, Router could fail due to RPATH related issues.
       CMake now uses -DWITH_STATIC=yes for OS X when executing
       cmake for the binaries. (Bug #23507484)

     * When the max_connect_errors variable was set to the
       maximum possible value (highest boundary value of
       4294967295), connection errors would report the value as
       a negative value, such as -1. (Bug #22745790)

     * There was inconsistent behavior with connection handling
       in relation to the max_connections setting. Now, the
       counter is incremented before the thread is spawned in
       the Routing plugin, because getting the server socket
       takes time and client connections could have been
       accepted after the max number of connections was reached.
       (Bug #22705168)

     * An exception thrown inside a plugin would cause the
       process to be terminated unconditionally. (Bug #22546709,
       Bug #79983)
