### [`v2.13.10`](https://togithub.com/scala/scala/releases/tag/v2.13.10): Scala 2.13.10
[Compare Source](https://togithub.com/scala/scala/compare/v2.13.9...v2.13.10)
The Scala team at Lightbend is pleased to announce the availability of Scala 2.13.10.
The following changes are highlights of this release:
##### Binary compatibility regression fixed
- Fix 2.13.9 regression which broke binary compatibility of case classes which are also value classes ([#10155](https://togithub.com/scala/scala/pull/10155))
Library maintainers should avoid publishing libraries using Scala 2.13.9.
##### Other notable changes
- Fix 2.13.9 regression in linting, causing spurious "variable x is never used" warnings ([#10154](https://togithub.com/scala/scala/pull/10154))
- `-Xsource:3` now respects refinements by whitebox macro overrides ([#10160](https://togithub.com/scala/scala/pull/10160) by [@som-snytt](https://togithub.com/som-snytt))
- Scaladoc tool: fix parsing bug which could cause very slow performance or incorrect output ([#10175](https://togithub.com/scala/scala/pull/10175) by [@liang3zy22](https://togithub.com/liang3zy22))
- Restore `-Vprint-args`, for echoing arguments provided to compiler ([#10164](https://togithub.com/scala/scala/pull/10164) by [@som-snytt](https://togithub.com/som-snytt))
For the complete 2.13.10 change lists, see [all merged PRs](https://togithub.com/scala/scala/pulls?q=is%3Amerged%20milestone%3A2.13.10) and [all closed bugs](https://togithub.com/scala/bug/issues?utf8=%E2%9C%93\&q=is%3Aclosed+milestone%3A2.13.10).
#### Compatibility
As usual for our minor releases, Scala 2.13.10 is [binary-compatible](https://docs.scala-lang.org/overviews/core/binary-compatibility-of-scala-releases.html) with the whole Scala 2.13 series.
Upgrading from 2.12? Enable `-Xmigration` while upgrading to request migration advice from the compiler.
#### Contributors
A big thank you to everyone who's helped improve Scala by reporting bugs, improving our documentation, spreading kindness in discussions around Scala, and submitting and reviewing pull requests! You are all magnificent.
We especially acknowledge and thank A. P. Marki, also known as Som Snytt, who is responsible for an especially large share of the improvements in this release.
This release was brought to you by 6 contributors, according to `git shortlog -sn --no-merges @ ^v2.13.9 ^2.12.x`. Thank you A. P. Marki, Liang Yan, Seth Tisue, Antoine Parent, Luc Henninger, 梦境迷离.
Thanks to [Lightbend](https://www.lightbend.com/scala) for their continued sponsorship of the Scala core team’s efforts. Lightbend offers [commercial support](https://www.lightbend.com/lightbend-platform-subscription) for Scala.
#### Scala 2.13 notes
The [release notes for Scala 2.13.0](https://togithub.com/scala/scala/releases/v2.13.0) have important information applicable to the whole 2.13 series.
#### Obtaining Scala
Scala releases are available through a variety of channels, including (but not limited to):
- Bump the `scalaVersion` setting in your sbt-based project
- Download a distribution from [scala-lang.org](https://scala-lang.org/download/2.13.10.html)
- Obtain JARs via [Maven Central](https://search.maven.org/search?q=g:org.scala-lang%20AND%20v:2.13.10)
### [`v2.13.9`](https://togithub.com/scala/scala/releases/tag/v2.13.9): Scala 2.13.9
[Compare Source](https://togithub.com/scala/scala/compare/v2.13.8...v2.13.9)
The following changes are highlights of this release:
##### Regression
Library maintainers should avoid publishing libraries using Scala 2.13.9. Please use [2.13.10](https://togithub.com/scala/scala/releases/v2.13.10) instead. 2.13.9 has a [regression](https://togithub.com/scala/bug/issues/12650) where binary-incompatible bytecode is emitted for case classes which are also value classes (`case class ... extends AnyVal`).
##### Compatibility with Scala 3
- Tasty Reader: Add support for Scala 3.2 ([#10068](https://togithub.com/scala/scala/pull/10068))
- Tasty Reader: Restrict access to experimental definitions ([#10020](https://togithub.com/scala/scala/pull/10020))
- To aid cross-building, accept and ignore `using` in method calls ([#10064](https://togithub.com/scala/scala/pull/10064) by [@som-snytt](https://togithub.com/som-snytt))
- To aid cross-building, allow `?` as a wildcard even without `-Xsource:3` ([#9990](https://togithub.com/scala/scala/pull/9990))
- Make Scala-3-style implicit resolution explicitly opt-in rather than bundled in `-Xsource:3` ([#10012](https://togithub.com/scala/scala/pull/10012) by [@povder](https://togithub.com/povder))
- Prefer type of overridden member when inferring (under `-Xsource:3`) ([#9891](https://togithub.com/scala/scala/pull/9891) by [@som-snytt](https://togithub.com/som-snytt))
##### JDK version support
- Make `-release` more useful, deprecate `-target`, align with Scala 3 ([#9982](https://togithub.com/scala/scala/pull/9982) by [@som-snytt](https://togithub.com/som-snytt))
- Support JDK 19 ([#10001](https://togithub.com/scala/scala/pull/10001) by [@Philippus](https://togithub.com/Philippus))
##### Warnings and lints
- Add `-Wnonunit-statement` to warn about discarded values in statement position ([#9893](https://togithub.com/scala/scala/pull/9893) by [@som-snytt](https://togithub.com/som-snytt))
- Make unused-import warnings easier to silence (support filtering by `origin=`) ([#9939](https://togithub.com/scala/scala/pull/9939) by [@som-snytt](https://togithub.com/som-snytt))
- Add `-Wperformance` lints for `*Ref` boxing and nonlocal `return` ([#9889](https://togithub.com/scala/scala/pull/9889) by [@som-snytt](https://togithub.com/som-snytt))
##### Language improvements
- Improve support for Unicode supplementary characters in identifiers and string interpolation ([#9805](https://togithub.com/scala/scala/pull/9805) by [@som-snytt](https://togithub.com/som-snytt))
##### Compiler options
- Use subcolon args to simplify optimizer options ([#9810](https://togithub.com/scala/scala/pull/9810) by [@som-snytt](https://togithub.com/som-snytt))
- For troubleshooting compiler, add `-Vdebug-type-error` (and remove `-Yissue-debug`) ([#9824](https://togithub.com/scala/scala/pull/9824) by [@tribbloid](https://togithub.com/tribbloid))
##### Security
- Error on source files with Unicode directional formatting characters ([#10017](https://togithub.com/scala/scala/pull/10017))
- Prevent `Function0` execution during `LazyList` deserialization ([#10118](https://togithub.com/scala/scala/pull/10118))
##### Bugfixes
- Emit all bridge methods non-final (perhaps affecting serialization compat) ([#9976](https://togithub.com/scala/scala/pull/9976))
- Fix null-pointer regression in `Vector#prependedAll` and `Vector#appendedAll` ([#9983](https://togithub.com/scala/scala/pull/9983))
- Improve concurrent behavior of Java `ConcurrentMap` wrapper
([#10027](https://togithub.com/scala/scala/pull/10027) by [@igabaydulin](https://togithub.com/igabaydulin))
- Preserve null policy in wrapped Java `Map`s ([#10129](https://togithub.com/scala/scala/pull/10129) by [@som-snytt](https://togithub.com/som-snytt))
Changes that shipped in Scala 2.12.16 and 2.12.17 are also included in this release.
