2.13.6->2.13.14Release Notes
scala/scala (scala)
### [`v2.13.14`](https://togithub.com/scala/scala/releases/tag/v2.13.14): Scala 2.13.14 [Compare Source](https://togithub.com/scala/scala/compare/v2.13.13...v2.13.14) The Scala team at Lightbend is pleased to announce Scala 2.13.14. The following changes are highlights of this release: ##### Align with Scala 3 - Introduce `-Xsource-features`, for customizing the behavior of `-Xsource:3` and `-Xsource:3-cross` ([#10709](https://togithub.com/scala/scala/pull/10709)) - A section of the Scala 3 Migration Guide documents these flags: [documentation](https://docs.scala-lang.org/scala3/guides/migration/tooling-scala2-xsource3.html) ##### Regression fixes - Rename `-Xlint:named-booleans` to `-Wunnamed-boolean-literal` (and no longer include it in `-Xlint`) ([#10704](https://togithub.com/scala/scala/pull/10704) by [@som-snytt](https://togithub.com/som-snytt)) - Fix `ArrayBuilder` regression in Scala 2.13.13 (`OutOfMemoryError` when adding empty arrays) ([#10722](https://togithub.com/scala/scala/pull/10722) by [@som-snytt](https://togithub.com/som-snytt)) - Fix 2.13.13 regression in Scaladoc compilation when using Scala 3 definitions ([#10700](https://togithub.com/scala/scala/pull/10700) by [@bishabosha](https://togithub.com/bishabosha)) ##### Other improvements - Unused warnings: for macros, by default, look for usages in expansion ([#10693](https://togithub.com/scala/scala/pull/10693) by [@som-snytt](https://togithub.com/som-snytt)) - REPL: Upgrade to JLine 3.25.1 (was 3.24.1) ([#10717](https://togithub.com/scala/scala/pull/10717)) - Remove `SHELLOPTS=vi` and `-Xjline support`; reinstate `-Xnojline` ([#10716](https://togithub.com/scala/scala/pull/10716) by [@hvesalai](https://togithub.com/hvesalai)) ##### More changes For the complete 2.13.14 change lists, see [all merged PRs](https://togithub.com/scala/scala/pulls?q=is%3Amerged%20milestone%3A2.13.14) and [all closed bugs](https://togithub.com/scala/bug/issues?utf8=%E2%9C%93\&q=is%3Aclosed+milestone%3A2.13.14). #### Compatibility As usual for our minor releases, Scala 2.13.14 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 many of the improvements in this release. This release was brought to you by 9 contributors, according to `git shortlog -sn --no-merges @ ^v2.13.13 ^2.12.x`. Thank you A. P. Marki, Lukas Rytz, Seth Tisue, Scala Steward, Jamie Thompson, Antoine Amiguet, Heikki Vesalainen, Robert Stoll, guqicun. Thanks to [Lightbend](https://www.lightbend.com/scala) for their continued sponsorship of the Scala 2 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 `using scala` setting in your Scala CLI project - Bump the `scalaVersion` setting in your sbt or Mill project - Download a distribution from [scala-lang.org](https://scala-lang.org/download/2.13.14.html) - Obtain JARs via [Maven Central](https://search.maven.org/search?q=g:org.scala-lang%20AND%20v:2.13.14) ### [`v2.13.13`](https://togithub.com/scala/scala/releases/tag/v2.13.13): Scala 2.13.13 [Compare Source](https://togithub.com/scala/scala/compare/v2.13.12...v2.13.13) The Scala team at Lightbend is pleased to announce Scala 2.13.13. The following changes are highlights of this release: ##### Language - Support binary integer literals using `0b`, as in Java ([#10656](https://togithub.com/scala/scala/pull/10656) by [@som-snytt](https://togithub.com/som-snytt)) ##### Compatibility - TASTy reader: support Scala 3.4 ([#10670](https://togithub.com/scala/scala/pull/10670) by [@bishabosha](https://togithub.com/bishabosha)) - Support certain Java libraries compiled on JDK 21 ([#10675](https://togithub.com/scala/scala/pull/10675) by [@SethTisue](https://togithub.com/SethTisue)) - For JDK 22 support, upgrade to ASM 9.6 ([#10576](https://togithub.com/scala/scala/pull/10576) by [@Philippus](https://togithub.com/Philippus)) ##### Align with Scala 3 - Allow either `-Xsource:3` (for preparing to switch to 3) or `-Xsource:3-cross` (for crossbuilding on 2 and 3); some existing users of `-Xsource:3` should switch to `-Xsource:3-cross` to avoid unwanted behavior changes ([#10573](https://togithub.com/scala/scala/pull/10573) by [@som-snytt](https://togithub.com/som-snytt)) - A new section in the Scala 3 Migration Guide documents `-Xsource:3` and `-Xsource:3-cross`: [documentation](https://docs.scala-lang.org/scala3/guides/migration/tooling-scala2-xsource3.html) - For migration to 3, accommodate case companion as function ([#10648](https://togithub.com/scala/scala/pull/10648) by [@som-snytt](https://togithub.com/som-snytt)) - Scala 3 migration warning for implicits found in package prefix ([#10621](https://togithub.com/scala/scala/pull/10621) by [@lrytz](https://togithub.com/lrytz)) ##### Other improvements - `-Yrelease` supplements `-release`, allows access to additional JVM packages ([#10543](https://togithub.com/scala/scala/pull/10543) by [@som-snytt](https://togithub.com/som-snytt)) - `-Xlint` now enables `-Xlint:named-booleans` to lint unnamed boolean literal args ([#10612](https://togithub.com/scala/scala/pull/10612) by [@som-snytt](https://togithub.com/som-snytt)) - Respect `java.lang.Deprecated` annotation even in Scala sources ([#10517](https://togithub.com/scala/scala/pull/10517) by [@kapunga](https://togithub.com/kapunga)) - Optimize tail recursion on effectively final methods even when `final` keyword is absent ([#10629](https://togithub.com/scala/scala/pull/10629) by [@som-snytt](https://togithub.com/som-snytt)) - Add `-Xlint:pattern-shadow` to lint pattern varids which are backquotable ([#8806](https://togithub.com/scala/scala/pull/8806) by [@som-snytt](https://togithub.com/som-snytt)) - In mixed compilation, allow Java sources to reference `MODULE$` ([#10644](https://togithub.com/scala/scala/pull/10644) by [@som-snytt](https://togithub.com/som-snytt)) - Scaladoc: re-align `-doc-source-url` behavior with 2.12 ([#10581](https://togithub.com/scala/scala/pull/10581) by [@lrytz](https://togithub.com/lrytz)) ##### Known issues - When upgrading to 2.13.13, existing users of `-Xsource:3` should explicitly consider switching to `-Xsource:3-cross`. Some behaviors of `-Xsource:3` have changed, e.g. in result type inference for inherited methods; see [new doc page](https://docs.scala-lang.org/scala3/guides/migration/tooling-scala2-xsource3.html) for details - Some library authors who were already using `-Xsource:3` are getting MiMa failures when upgrading to 2.13.13 and switching from `-Xsource:3` to `-Xsource:3-cross`. If you’re in this situation, you may need to wait for 2.13.14; see [scala/bug#12961](https://togithub.com/scala/bug/issues/12961) - Users of sbt must upgrade to sbt 1.9.9 to use the `console` task to access the 2.13.13 REPL ([sbt/sbt#7502](https://togithub.com/sbt/sbt/issues/7502)); error message is `NoSuchMethodError: org.jline.utils.AttributedString.fromAnsi` - Regression: Scaladoc generation may fail if you are using the TASTy reader to access Scala 3 dependencies ([scala/bug#12955](https://togithub.com/scala/bug/issues/12955)); error message is "Unsupported Scala 3 generic tuple type"; we'll fix it in 2.13.14 - Regression: on JDK 11 (but not 8 or 17 or 21), the REPL prints a harmless "illegal reflective access" warning at startup ([scala/bug#12957](https://togithub.com/scala/bug/issues/12957)); we'll fix it in 2.13.14 - The inclusion of `-Xlint:named-booleans` in `-Xlint` ([#10612](https://togithub.com/scala/scala/pull/10612)) has already proved at least somewhat controversial, and will likely be adjusted for 2.13.14; you can leave feedback on this at [#10704](https://togithub.com/scala/scala/pull/10704) ##### More changes For the complete 2.13.13 change lists, see [all merged PRs](https://togithub.com/scala/scala/pulls?q=is%3Amerged%20milestone%3A2.13.13) and [all closed bugs](https://togithub.com/scala/bug/issues?utf8=%E2%9C%93\&q=is%3Aclosed+milestone%3A2.13.13). #### Compatibility As usual for our minor releases, Scala 2.13.13 is [binary-compatible](https://docs.scala-lang.org/overviews/core/binary-compatibility-of-scala-releases.html) with the whole Scala 2.13 series.

The following changes are highlights of this release: ##### Feature: Quickfixes For some errors and warnings, the compiler now suggests an edit that could fix the issue. Tooling such as IDEs can then offer the edits, or the compiler itself will make the change if run again with `-quickfix`. - Implement quickfixes, aka actionable diagnostics (via `CodeAction`) ([#10406](https://togithub.com/scala/scala/pull/10406) by [@eed3si9n](https://togithub.com/eed3si9n)) - Add `-quickfix` compiler option to apply quickfixes to source files ([#10482](https://togithub.com/scala/scala/pull/10482) by [@lrytz](https://togithub.com/lrytz)) - Add quickfixes to some warnings and errors ([#10484](https://togithub.com/scala/scala/pull/10484) by [@lrytz](https://togithub.com/lrytz)) ##### Align with Scala 3 - Emit migration warnings under `-Xsource:3` as fatal warnings, not errors ([#10439](https://togithub.com/scala/scala/pull/10439) by [@som-snytt](https://togithub.com/som-snytt), [#10511](https://togithub.com/scala/scala/pull/10511)) - `-Xmigration` will demote the errors to warnings - `-Wconf:cat=scala3-migration:s` will silence these errors/warnings altogether - Warn about `@elidable` under `-Xsource:3` ([#10377](https://togithub.com/scala/scala/pull/10377) by [@som-snytt](https://togithub.com/som-snytt)) ##### Collections - `IndexedSeq#head` now throws `NoSuchElementException` (not `IndexOutOfBoundsException`) ([#10392](https://togithub.com/scala/scala/pull/10392) by [@som-snytt](https://togithub.com/som-snytt)) ##### Regression fixes - Deduplicate `JavaDeprecatedAttr` in `ClassfileParser` ([#10422](https://togithub.com/scala/scala/pull/10422) by [@som-snytt](https://togithub.com/som-snytt)) - Avoid brittle flags encoding for Java enums ([#10424](https://togithub.com/scala/scala/pull/10424) by [@som-snytt](https://togithub.com/som-snytt)) ##### Scaladoc tool changes Library authors should be aware that the behavior of `-doc-source-url` has changed, as follows: - [https://github.com/scala/bug/issues/12867](https://togithub.com/scala/bug/issues/12867) You may need to adjust your build accordingly, to avoid generating broken source links. ##### Tooling The following change is mainly of concern to tooling maintainers. - In-source sbt compiler bridge ([#10472](https://togithub.com/scala/scala/pull/10472) by [@lrytz](https://togithub.com/lrytz)) ##### Other notable changes For the complete 2.13.12 change lists, see [all merged PRs](https://togithub.com/scala/scala/pulls?q=is%3Amerged%20milestone%3A2.13.12) and [all closed bugs](https://togithub.com/scala/bug/issues?utf8=%E2%9C%93\&q=is%3Aclosed+milestone%3A2.13.12). #### Compatibility As usual for our minor releases, Scala 2.13.12 is [binary-compatible](https://docs.scala-lang.org/overviews/core/binary-compatibility-of-scala-releases.html) with the whole Scala 2.13 series.
