released sbt 1.12.13, featuring file permissions issue fix
eed3si9n.com/sbt-1.12.13 #Scala
sbt 2.x keeps mostly backward compatibility only, for example by adding methods and features in minor releases, so as long as Scala library also keeps backward compatibility, I think it should be ok for sbt 2.x to bump to Scala 3.9 later. question is should we adopt Scala 3.10 etc
