Scala 3.3.9 LTS is now available!
Scala 3.3.9 LTS is now available, backporting most bugfixes and some improvements from Scala 3.9.0. All backported changes were tested against over 1500 projects in the Scala 3 Open Community Build to confirm binary and source compatibility. Notable fixes include smaller Scaladoc doc jars from dropping custom fonts, improved Java generic signatures for higher-kinded types and value classes, exhaustiveness checking for sealed abstract Java classes, and a fix for Scaladoc crashing with an NPE on JDK 25. The 3.3.x LTS series will now be supported until September 2027, while 3.9.x is supported until September 2029 or later.
