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
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
More changes

For the complete 2.13.16 change lists, see all merged MRs and all closed bugs.

Compatibility

As usual for our minor releases, Scala 2.13.16 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.

v2.13.13: Scala 2.13.13

Compare Source

The Scala team at Lightbend is pleased to announce Scala 2.13.13.

The following changes are highlights of this release:

Language
Compatibility
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 by @​som-snytt)
    • A new section in the Scala 3 Migration Guide documents -Xsource:3 and -Xsource:3-cross: documentation
  • For migration to 3, accommodate case companion as function (#​10648 by @​som-snytt)
  • Scala 3 migration warning for implicits found in package prefix (#​10621 by @​lrytz)
Other improvements
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 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
  • 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); 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); 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); we'll fix it in 2.13.14
  • The inclusion of -Xlint:named-booleans in -Xlint (#​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

v2.13.12: Scala 2.13.12

Compare Source

The Scala team at Lightbend is pleased to announce Scala 2.13.12.

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.

Align with Scala 3
  • Emit migration warnings under -Xsource:3 as fatal warnings, not errors (#​10439 by @​som-snytt, #​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 by @​som-snytt)
Collections
  • IndexedSeq#head now throws NoSuchElementException (not IndexOutOfBoundsException) (#​10392 by @​som-snytt)
Regression fixes
Scaladoc tool changes

Library authors should be aware that the behavior of -doc-source-url has changed, as follows:

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.

Other notable changes

For the complete 2.13.11 change lists, see all merged MRs and all closed bugs.

Known issues

A few regressions have been discovered:

  • Exhaustivity checker emits spurious warning when matching on Java enum type (2.13.11 regression) (scala/bug#12800)
  • Duplicated @Deprecated annotations when extending Java interface with deprecated default method cause java.lang.annotation.AnnotationFormatError when accessed via Java reflection (2.13.11 regression) (scala/bug#12799)

We'll address these in Scala 2.13.12.
