v2.13.17: Scala 2.13.17

Compare Source

The Scala team at Akka is pleased to announce Scala 2.13.17.

This release is compatible with the new JDK 25 LTS.

The following are highlights of this release:

Compatibility

• JDK 25 support in optimizer (#​11046)
• Support Scala 3.7 in the TASTy reader (#​11100)
• When parsing Java sources, skip JDK 21+’s JEP 445 compact compilation units (#​11066)

Breaking changes

• Mix in the productPrefix hash statically in case class hashCode (#​11023)
  • The synthetic hashCode method of a case class no longer calls productPrefix. This changes the hash code of case classes that override productPrefix.
• Improve scala.util.Using suppression order (NonFatal suppresses ControlThrowable) (#​11000 by @​NthPortal)
  • When multiple exceptions are thrown, a predefined order determines which exception is rethrown and which is attached as "suppressed"
  • Users of scala-collection-compat can upgrade to 2.14.0 to get the same behavior change
  • If you use Using in a project that crossbuilds to Scala 3, you may wish to wait for a Scala 3 release that includes the 2.13.17 standard library, or use a dependency override to force the upgrade in your build

Features and notable changes

• New "a type was inferred to be kind-polymorphic" lint (#​10976)
  • Unwanted false positives? See scala/bug#13128 for discussion and workarounds
• Fix AnnotationInfo when using named/default arguments, support custom annotation subclasses (#​10976)
  • Users can now define, for example, class nodep extends annotation.nowarn("cat=deprecation") and use @nodep to silence deprecations
• Show nowarn/-Wconf filters for a warning with @nowarn("verbose") (#​10985)
• Use toVector for XML literal sequences (#​11065)

Scala 3 compatibility and migration

• Allow using -Xsource-features without -Xsource:3 (#​11123)
• Lint inferred structural types (#​10942)
  • Unwanted "has an inferred structural type" warnings? See PR for discussion and workarounds.
• Port summonIgnoring from 3.7 as c.inferImplicitValueIgnoring (#​11068 by @​MateuszKubuszok)

Notable bug fixes

• Allow optimizer use within Bazel (don't attempt inlining methods without instructions) (#​11016)
• Reduce memory footprint of evaluated elements in LazyList (#​10937)
• Deregister stale callbacks in Future.firstCompletedOf (prevents memory leaks) (#​10927)
• Require -Xsource-features:eta-expand-always for eta-expansion without an expected type (#​10907 by @​som-snytt)

More changes

For the complete 2.13.17 change lists, see all merged PRs and all closed bugs.

Compatibility

As usual for our minor releases, Scala 2.13.17 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.

v2.13.16: Scala 2.13.16

Compare Source

The Scala team at Akka (formerly Lightbend) is pleased to announce Scala 2.13.16.

The following changes are highlights of this release:

Breaking change

• On the empty string, .tail and .init now throw (instead of returning the empty string) (#​10851 by @​sh0hei)
  • This is a bugfix, but be aware that existing code might, perhaps inadvertently, be relying on the old behavior

Compatibility

• Support Scala 3.6 in TASTy reader (#​10893)
• Support JDK 24 in optimizer (via ASM upgrade) (#​10888 by @​Philippus)

REPL

• REPL: JLine 3.27.1 (was 3.26.3) and on Windows use JNI not JNA (#​10899, #​10898, #​10882)
  • These upgrades hopefully won't be noticed, but, REPL users on Windows take note
  • JNA is no longer a dependency of scala-compiler.jar

Align with Scala 3

• Under -Xsource:3, deprecate infix named args (#​10857 by @​som-snytt)

Errors and warnings

• Fix 2.13.15-only false positives with -Wunused:patvars (#​10870 by @​som-snytt)

Collections

• Do not use rangeHash when rangeDiff is 0 (#​10912 by @​Friendseeker)
  • This may affect fragile code relying on ordering of hash-based collections
• Deprecate collection.mutable.AnyRefMap (#​10862 by @​wangyum)
  • Since Scala 2.13.0 it has no performance advantage over collection.mutable.HashMap
