- Fix 2.13.7 regression in implicit resolution ([#9829](https://togithub.com/scala/scala/pull/9829) by [@joroKr21](https://togithub.com/joroKr21))
- Fix 2.13.7 `releaseFence` regression affecting GraalVM compatibility ([#9825](https://togithub.com/scala/scala/pull/9825) by [@lrytz](https://togithub.com/lrytz))
- Fix 2.13.7 regression affecting wildcards and F-bounded types ([#9806](https://togithub.com/scala/scala/pull/9806) by [@joroKr21](https://togithub.com/joroKr21))
A few small changes that will ship in 2.12.16 are also included in this release.
For the complete 2.13.8 change lists, see [all merged PRs](https://togithub.com/scala/scala/pulls?q=is%3Amerged%20milestone%3A2.13.8) and [all closed bugs](https://togithub.com/scala/bug/issues?utf8=%E2%9C%93\&q=is%3Aclosed+milestone%3A2.13.8).
##### Compatibility
As usual for our minor releases, Scala 2.13.8 is binary-compatible with the whole Scala 2.13 series.
Upgrading from 2.12? Enable `-Xmigration` while upgrading to request migration advice from the compiler.
