Version 8.0.21 is the latest General Availability release of the 8.0 series of MySQL Connector/J. 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.
The required versions of the 3rd-party libraries needed for running or compiling Connector/J have been changed; new requirements for additional libraries have also been added. See Installing Connector/J from a Binary Distribution and Installing from Source for details. (WL #14042, WL #14051)
