The Scala team at Lightbend is pleased to announce the availability of Scala 2.13.10.

The following changes are highlights of this release:

Library maintainers should avoid publishing libraries using Scala 2.13.9.

Other notable changes

  • -Xsource:3 now respects refinements by whitebox macro overrides (#10160 by @som-snytt)
  • Scaladoc tool: fix parsing bug which could cause very slow performance or incorrect output (#10175 by @liang3zy22)
  • Restore -Vprint-args, for echoing arguments provided to compiler (#10164 by @som-snytt)

For the complete 2.13.10 change lists, see all merged PRs and all closed bugs.
