v2.13.18: Scala 2.13.18

Compare Source

The Scala team at Akka is pleased to announce Scala 2.13.18.

This release fixes several regressions from 2.13.17. It is compatible with JDKs 8 to 26.

The following are highlights of this release:

Restore traditional behavior when passing a null array to a varargs method in Scala 3

When passing an array as "sequence argument" to a varargs method, method(arg: _*), the array is converted to a Seq.

In Scala 3 (the syntax is method(arg*)), this conversion is done by the ScalaRunTime.wrapXArray methods. These methods were simplified in 2.13.17, which changed the semantics of a method((null: Array[T])*) invocation.

#​11165 restores the previous null handling semantics.

Fixes for false positive warnings
  • #​11162 reverts -Xlint:infer-any to the behavior of 2.13.16. The lint was extended in 2.13.17 to warn whenever Nothing is inferred for a higher-kinded type parameter T[_]. The new warning showed up in many projects: often as a false positive, but even the "true" positive warning was considered unhelpful / spurious in real-world use cases.
  • Fix false positive unused warning for private val used in annotation #​11149
  • Fix false positive -Xlint:universal-methods warning in synthetic code #​11159
JDK 26 support
  • Compiling on Java 26 is now supported #​11179
New @uncheckedOverride annotation

The new @uncheckedOverride annotation is equivalent to the override keyword, except that it allows to override nothing. This is useful when cross-building: a method may override or not, depending on the version of some dependency. #​11179

GPG key change

This release is signed with a different GPG key than previous Scala 2 releases. The new key is the same one used by Scala 3. #​11158

Other notable changes
  • On Java 25+, sbt run now detects main methods that are non-static, non-public or without parameter list #​11137
  • Regression fix: 2.13.17 was accidentally dropping certain annotations #​11173
  • Deprecate the -Xmain-class compiler flag #​11156
More changes

For the complete 2.13.18 change lists, see all merged PRs and all closed bugs.

Compatibility

As usual for our minor releases, Scala 2.13.18 is binary-compatible with the whole Scala 2.13 series.

Scala 2.13 notes

The release notes for Scala 2.13.0 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
  • Obtain JARs via Maven Central

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.

See below for known issues / regressions in this release.

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
  • 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)
    • In case this warning is undesired, it can be disabled using -Xlint:_,-infer-structural
  • 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.

Known issues / regressions

False positive lint warning: a type was inferred to be kind-polymorphic

  • A new warning was added to the existing -Xlint:infer-any flag (which is also enabled with plain -Xlint)
  • The implementation issues false positive warnings
  • To revert back to the behavior of Scala 2.13.16, add -Wconf:cat=lint-infer-any&msg=kind-polymorphic:s
  • See scala/scala#13128 for details

Scaladoc @define no longer works if the doc comment is on an object

-Wunused:privates now warns about unused private final val declarations. When such a val is only referenced as argument to a Java annotation, it is incorrectly reported as unused

  • See scala/bug#13130 for details
  • Workaround: add @nowarn("cat=unused-privates") to the val declaration

Semantic change when passing a null sequence parameter in Scala 3, i.e., foo((null: Array[T])*). Within def foo(xs: T*), the value xs is no longer null.

  • Merely updating scala-library on the classpath to 2.13.17 can change the runtime behavior of previously compiled code
  • See #​11165 for details

Compatibility

As usual for our minor releases, Scala 2.13.17 is binary-compatible with the whole Scala 2.13 series.

v2.13.16: Scala 2.13.16

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
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
Errors and warnings
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
