Dear MySQL users,

MySQL Router 2.1.5 GA is the third GA release for MySQL Router 2.1.

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

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.

MySQL Router 2.1 also introduces the following additions:

* Automatic setup/bootstrap with a MySQL InnoDB cluster
* Support for the new X protocol
* Support for deployments inside self-contained directories
* Easy and secure password management using a built-in keyring

You can download MySQL Router from
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.

Changes in MySQL Router 2.1.5 (2018-02-02, General Availability)

   Functionality Added or Changed

     * Bootstrap now accepts any member of an InnoDB cluster and
       automatically finds and reconnects to a writable primary.
       (Bug #25489509)

   Bugs Fixed

     * Configuring MySQL Router with sockets would create a
       socket that was only accessible by the MySQL Router user.
       (Bug #27179456, Bug #88667)

     * The apt purge process did not remove the
       /var/{lib,log,run}/mysql router directories. (Bug

     * Router assumed that a resulting socket from accept()ing a
       socket would be always blocking. On Solaris and Windows
       this assumption isn't the case and resulted a broken
       connections with large result sets. (Bug #26834769)

     * The maximum number of concurrent client connections was
       increased from about 500 to over 5000, a limit now
       dependent on the operation system. To achieve this,
       select() based fd event calls were replaced by poll() (or
       WSAPoll() on Windows). (Bug #22661705, Bug #80260)
