MySQL Router 8.0.18 for MySQL Server 8.0 and 5.7 has been released

Dear MySQL users,

MySQL Router 8.0.18 is a new release for MySQL Router 8.0 series.

MySQL Router 8.0 is highly recommended for use with MySQL Server 8.0 and 5.7.
Please upgrade to MySQL Router 8.0.18.

The MySQL Router is a new building block for high availability solutions
based on MySQL InnoDB clusters.

By taking advantage of the new Group Replication technology, and
combined with the MySQL Shell, InnoDB clusters provide an integrated
solution for high availability and scalability for InnoDB based MySQL
databases, that does not require advanced MySQL expertise.

The deployment of applications with high availability requirements is
greatly simplified by MySQL Router. MySQL client connections are
transparently routed to online members of a InnoDB cluster, with MySQL
server outages and cluster reconfigurations being automatically handled
by the Router.

To download MySQL Router 8.0.18, see the "General Availability (GA)
Releases" tab at Package
binaries are available for several platforms and also as a source code

Documentation for MySQL Router can be found at


Changes in MySQL Router 8.0.18 (2019-10-14)

Bugs Fixed

     * On Windows, ProcessLauncher-related error handling was
       improved. (Bug #30188010)

     * Improved SQL quoting by the bootstrap process, which
       previously did not quote the username in queries. (Bug

     * On MacOS, Router failed to start after a successful
       bootstrap because the loader could not locate the SSL
       libraries. (Bug #30096843)

     * Executing python2.7 install failed to create the
       mysqlx folder for commercial portable packages. (Bug

     * SIGTRAP is now handled the same way as SIGINT in normal
       operations, and SIGTRAP allows debugger (such as gdb) to
       jump in. (Bug #29843245)

     * The internal REST API add path functionality did not
       always remove the current path first, which could cause
       an unexpected halt. (Bug #29833031)

     * Router could halt unexpectedly if unable to spawn another
       thread. (Bug #29759391)

     * On Windows 10, Router built with -DINSTALL_LAYOUT=WIN
       would create a directory named "ENV{APPDATA}" during
       bootstrap. (Bug #29160784)
