Spring Boot 2.0.0 M5 has been released and is now available from our milestone repository. This release closes 168 issues and pull requests and continues our progress towards 2.0 GA. Thanks to everyone that has contributed!

This milestone refines a number of items from M4, and provides a number of notable new features:

• Initial support for Java 9 - We'll continue to refine Java 9 support, but this release should work for basic applications. Check out this wiki page for more details.
• OAuth 2.0 Client support from Spring Security - Spring Security is starting to ship more OAuth 2.0 features. This release of Spring Boot provides auto-configuration for Spring Security's OAauth 2.0 client support.
• JSON-B Support - We now offer support for JSON-B alongside our existing Jackson and Gson integrations. We continue to recommend Jackson as our default choice.
• Session Actuator endpoint - Users of Spring Session can now view and expire sessions directly from the actuator.

For a complete list of changes, and upgrade instructions, see the Spring Boot 2.0.0.M5 Release Notes on the WIKI.
