# 0.5.9 (2025-10-12) ## Supported Scala versions Scala Binary Version | Supported Scala Versions | -------------------- | ------------------------ | Scala 2.12 | 2.12.14 ... 2.12.20 | Scala 2.13 | 2.13.8 ... 2.13.17 | Scala 3 | 3.1.2 ... 3.1.3 3.2.0 ... 3.2.2 3.3.0 ... 3.3.7 LTS 3.4.0 ... 3.4.3 3.5.0 ... 3.5.2 3.6.2 ... 3.6.4 3.7.0 ... 3.7.3 | > Upon release of new Scala version (stable, or Scala 3 RC) version dependent artifacts would be published without a new release. > Potential runtime incompatibility: Scala Native Standard Library used in Scala 3.0-3.7 artifacts is based on the Scala 2.13.17 sources - it might lead to different behaviour when compared with execution using JVM due to [SIP-51](https://docs.scala-lang.org/sips/drop-stdlib-forwards-bin-compat.html). It is a well known issue caused by Scala Native build infrastructure limits and would be resolved since Scala 3.8.
