One of the most notable changes in this build is the long-awaited support for JUnit 5 M3, so if you plan to keep running JUnit 5 M2, you have to either use IntelliJ IDEA 2016.3 (or earlier), or manually include JUnit 5 M2 dependencies in your classpath (junit-platform-launcher, junit-platform-commons, junit-platform-engine; junit-jupiter-api and junit-jupiter-engine for Jupiter; and junit-vintage-engine for Vintage).
Speaking of JDK 9, IntelliJ IDEA 2016.3 won’t support builds 148 and up because they contain code that breaks things. Of course, we’re working to resolve this, and will support the latest JDK 9 builds in 2017.1 (its EAP may well start within the next few weeks).
In other news:
- Move Element Right/Left actions are now available for Groovy
- WebSphere support has been updated to v9
