JDK 12, 13, 14, and 15 are expected to work wherever JDK 11 does. The Scala community build now runs on JDK 15 (as well as 11 and 8).

As of October 2020, the [jdk12](https://github.com/scala/bug/labels/jdk12) and [jdk13](https://github.com/scala/bug/labels/jdk13) labels in scala/bug have no open bugs. New issues will likely be reported against the newer non-LTS [jdk14 label](https://github.com/scala/bug/labels/jdk14) and [jdk15 label](https://github.com/scala/bug/labels/jdk15) or the LTS [jdk11 label](https://github.com/scala/bug/labels/jdk11).

As far as we know, 12, 13, 14, and 15 are similar to 11 with respect to Scala compatibility.

## JDK 16 compatibility notes

JDK 16 prereleases are now available. The final release is [targeted](https://openjdk.java.net/projects/jdk/16/) for March 2021.

The Scala community build now runs on JDK 16. As of February 1, there are known issues on the [jdk16](https://github.com/scala/bug/labels/jdk16) label. We are working on it. We intend to ship improved JDK 16 support in Scala 2.12.14 ([release timing thread](https://contributors.scala-lang.org/t/scala-2-12-14-planning/4852/2)) and 2.13.5 ([release timing thread](https://contributors.scala-lang.org/t/scala-2-13-5-planning/4825/6)).

## Scala 3

The Scala 3.0.x series will support JDK 8, as well as 11 and beyond.
