v2.13.9

986dcc1

Scala 2.13.9

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 instead. 2.13.9 has a regression where binary-incompatible bytecode is emitted for case classes which are also value classes (case class ... extends AnyVal).

To aid cross-building, allow ? as a wildcard even without -Xsource:3 (#9990)
Make Scala-3-style implicit resolution explicitly opt-in rather than bundled in -Xsource:3 (#10012 by @povder)

Support JDK 19 (#10001 by @Philippus)

Warnings and lints

Add -Wnonunit-statement to warn about discarded values in statement position (#9893 by @som-snytt)
Make unused-import warnings easier to silence (support filtering by origin=) (#9939 by @som-snytt)
Add -Wperformance lints for *Ref boxing and nonlocal return (#9889 by @som-snytt)

Language improvements

Improve support for Unicode supplementary characters in identifiers and string interpolation (#9805 by @som-snytt)

Use subcolon args to simplify optimizer options (#9810 by @som-snytt)
For troubleshooting compiler, add -Vdebug-type-error (and remove -Yissue-debug) (#9824 by @tribbloid)

Security

Error on source files with Unicode directional formatting characters (#10017)
Prevent Function0 execution during LazyList deserialization (#10118)

Bugfixes

Emit all bridge methods non-final (perhaps affecting serialization compat) (#9976)
Fix null-pointer regression in Vector#prependedAll and Vector#appendedAll (#9983)
Improve concurrent behavior of Java ConcurrentMap wrapper
(#10027 by @igabaydulin)

and aids migration to Scala 2.13:

Under -Xsource:2.13, warn about changed precedence in imports (#10095)

and eases cross-compilation with Scala 3:

Accept and ignore using in method signature (to aid cross-building with Scala 3) (#10075)

and enables improved tooling:

Tooling support: Add a tree attachment to mark auto-applications (#10063)
Tooling support: Attachments for infix Apply and postfix Select (#10042)

v2.12.16

c850a83

Scala 2.12.16

This release improves compatibility with recent JDKs:

Use ASM 9.3, enabling JDK 19 support (#10000)
Make -target support JDK 8 through 19 (and deprecate 5 through 7) (#9916)
Fix codegen for MethodHandle.invoke (et al) under JDK 17 -release (#9930)
Deprecate AnyVal#formatted(formatString), to avoid conflict with JDK 15+ method (#9783)

and aids cross-compiling with Scala 3:

Allow ? as a wildcard even without -Xsource:3 (#10005)

and improves security and error reporting:

For security, error on source files with Unicode directional formatting characters (#10023, #10030)
Fix range position end for infix calls (#9761)

For complete 2.12.16 change lists, see all merged PRs and all closed bugs.

Known issue

Scala 2.12.16 contains a regression that was discovered after the artifacts were published. Only mixed compilation of Scala and Java source files together is affected, and only when the Scala code contains references to certain nested classes in the Java sources. The problem manifests as a compile-time type error. Follow link for details and workarounds. We'll fix the problem in Scala 2.12.17 which we expect to release in a few months.

Compatibility

As usual for our minor releases, Scala 2.12.16 is binary-compatible with the whole Scala 2.12 series.

Contributors

This release was brought to you by 18 contributors, according to git shortlog -sn --no-merges @ ^v2.12.15 ^2.11.x. Thank you Scala Steward, Seth Tisue, Lukas Rytz, Sébastien Doeraene, A. P.
