+---
+[Scala 3.3.1 LTS](https://github.com/lampepfl/dotty/releases/tag/3.3.1) is now available!
+
+This version adds support for records in Java dependencies of Scala projects. It also brings improvements to the bytecode generation and a new linting rule: `-Wnonunit-statement`.
+
+Apart from that, there is also a ton of bug fixes, frequently for more obscure bugs that were with us for many versions of the language.
