Dear MySQL users,

MySQL Connector/J 8.0.21 is the latest General Availability release of
the MySQL Connector/J 8.0 series.  It is suitable for use with MySQL
Server versions 8.0, 5.7, and 5.6.  It supports the Java Database
Connectivity (JDBC) 4.2 API, and implements the X DevAPI.

In the documentation for MySQL 8.0.21, we have started
changing the term "master" to "source", the term "slave" to
"replica", the term "whitelist" to "allowlist", and the term
"blacklist" to "blocklist". There are currently no changes to
the product's syntax, so these terms are still present in the
documentation where the current code requires their use. See
the blog post MySQL Terminology Updates
for more information.

This release includes the following new features and changes, also
described in more detail on

As always, we recommend that you check the "CHANGES" file in the
download archive to be aware of changes in behavior that might affect
your application.

To download MySQL Connector/J 8.0.21 GA, see the "General Availability
