We are pleased to announce the first release of MySQL Connector/J 6.0! This is a new branch of development, which breaks from some of the traditions of the very stable and very mature Connector/J 5.1 branch. We have combed through lots of code and refactored it in order to support development of future features including our X DevAPI implementation and support for X Protocol. This work manifests in a number of visible changes, including revising the growing set of connection and build properties.

Beginning with Connector/J 6.0, we are moving away from having one jar that supports all versions of Java. Instead we are building one jar/package for every supported version of Java. This simplifies the build process as well as lots of code that was required to support many versions of Java. The current package is built for Java 8.

Note that Connector/J 6.0.2 is a milestone release and not intended for production usage.

All changes are documented in the MySQL Connector/J 6.0 Developer Guide.

Updates to connection properties, including removal of several options that are no longer needed with the latest versions of MySQL and Java. Additionally, we removed some legacy behavioral options. You can see the changes in the documentation:
– Connector/J 6.0 Changes in Connection Properties

If you are building from source or running the test suite, check the following:
– Connector/J 6.0 Changes for Build Properties

Finally, API changes and package reorganizations are documented at:
– Changes in the Connector/J API

Release notes are available at Changes in MySQL Connector/J 6.0.2 (2016-04-11, Milestone 1).
