Dear MySQL users,

MySQL Router 2.1.4 GA is the second 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.

     * Stand-alone routing failed and produced errors when used
       with a valid URI. (Bug #25973199)
