Scala 2.13.15

The Scala team at Lightbend is pleased to announce Scala 2.13.15.

The following changes are highlights of this release:

Breaking changes

• -Wconf:x,y now means -Wconf:x -Wconf:y, with y overruling x, rather than the reverse (to align with Scala 3 and with user intuition) (#10708 by @​som-snytt)
• Compiler plugins: rework and improve phase assembly (#10687 by @​som-snytt)
  • Plugin authors should check to see if they are affected
  • Plugin users may see strange errors if a plugin is affected and not adjusted by its author
  • Most plugins are not affected

Compatibility

• Support JDK 23 in optimizer (via upgrade to patched ASM 9.7.0) (#10744)
• Support Scala 3.5 in TASTy reader (#10811 by @​bishabosha)
• REPL: JLine 3.26.3 (was 3.25.1) (#10827)

Features

• Support alternative JVM system images (via -system, like javac) (#10801 by @​szeiger)
• Add -Ycollect-statistics for collecting statistics without printing them (#10795 by @​szeiger)

Align with Scala 3

• Add -Xsource-features:double-definitions to warn or error for double definitions (#10846 by @​som-snytt)
• Under -Xsource:3, allow importing given, for cross-building (#10786 by @​som-snytt)
• Under -Xsource:3, remove by-name restriction for case copy (#10770 by @​som-snytt)

Errors and warnings

• Fix -Wconf and -nowarn to be more consistent (#10750 by @​som-snytt)
• Add -Wtostring-interpolated to warn if interpolator uses toString (#10776 by @​som-snytt)
• Improve inferred-Any lint (fixing false positives and false negatives) (#9452 by @​som-snytt)
• Fix false-positive unused warnings in for comprehensions (#10812 by @​som-snytt)
• Fix false-positive by-name implicit warnings with -Wmacros (#10781 by @​som-snytt)
• Mention if missing symbol is on the class path (#10774 by @​som-snytt)
• Avoid unused import warnings in REPL (#10769 by @​som-snytt)
• Add -Vcyclic to improve reporting of "cyclic reference" errors (#10680 by @​som-snytt)

More changes

For the complete 2.13.15 change lists, see all merged PRs and all closed bugs.

Compatibility

As usual for our minor releases, Scala 2.13.15 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.
