IntelliJ IDEA early access support for Java 15 preview features

[Tagir Valeev]

Hello!

I'm happy to announce that recent IntelliJ IDEA 2020.2 EAP has the
support of Java 15 preview features:
- Sealed types
- Local interfaces/enums
- Override on record accessors
- Access modifiers for canonical constructors
- Disabled field assignment in compact constructors.
Syntax highlighting, error highlighting, completion, and some
inspections/intention actions were updated to support new features.

IDEA 2020.2 will support both Java 14-preview and Java 15-preview
(Java 13-preview is dropped).

You can grab early access versions here:

The early access version is fully functional for 30 days.

Feel free to report any issues to our issue tracker (
https://youtrack.jetbrains.com/issues ) or just e-mailing me directly.

With best regards,
Tagir Valeev.
