Slick 3.2.0-RC1

We have just released Slick 3.2.0-RC1, the first release candidate for Slick 3.2.0. You can find the source code here: https://github.com/slick/slick/tree/3.2.0-RC1. Builds for Scala 2.11 and 2.12 are available from Maven Central, as usual. From this release on, Slick requires Java 8. Older JVMs are no longer supported.

This is the first version of Slick with official support for Scala 2.12.

These are the major changes in Slick 3.2:

• The Slick profiles (previously called “drivers”) for DB2, Oracle and SQL Server are now part of the core open source release. There is no separate Slick Extensions release anymore.
• Important bug fixes for asynchronous execution of database actions and other parts of the codebase.
• Logging of statement parameters.
• Improved documentation.
• Strip margins of multi-line SQL interpolator strings.
• JMX monitoring for AsyncExecutor workloads.

You can find details about upgrading from Slick 3.1 in the Migration Guide. Please provide feedback on the stability of this RC if you encounter any problems.
