v3.7.2

Compare Source

Highlights of the release

• Add an -Yimplicit-to-given flag for rewrites to easily test changes in the ecosystem #​22580
  This experimental flag when used in conjunction with --rewrite allows to migrate most of implicit definitions as given. It aims to ease with migration to new syntax, or testing how it would affect your code base.

• Bump Scala CLI to v1.8.4 (was v1.8.0) #​23538

  • Support for URLs in using file directives
  • Better support for the REPL with JDK 24+
  • experimental publish support for the Sonatype Central Portal
  • See full Scala CLI changelog

• Implement applied constructor types #​22543
  It introduces new syntax allowing for easier definition of tracked parameters under -language:experimental.modularity
  You can read more about this experimental feature in the Modularity Improvements proposal documentation.

Highlights of the release

• Support for JDK 24 #​22250
• REPL :silent command to toggle automatic printing of outputs #​22248
• REPL --repl-init-script: setting to run a code on startup #​22206
• Deprecated setting -Xno-decode-stacktraces is now an alias to -Xno-enrich-error-messages #​22208
• Annotation arguments are no longer lifted #​22035
• Experimental Capture Checking: Implement tracked members #​21761

Breaking changes

• Align @implicitNotFound and @implicitAmbigous with the language specification #​22371

  This change may impact users who previously used these annotations using variables or string interpolation.

  Previously, a bug in the Scala 3 compiler allowed non-literal strings to be passed as arguments to the @implicitNotFound and @implicitAmbiguous annotations.
  This could have affected how failed implicit search results were reported by the compiler.

  Starting from Scala 3.6.4, the arguments for these annotations must be string literals.
  If a message is too long, it can be concatenated using the + operator, allowing for constant folding.
