`v3.7.0`

`v3.6.4`

Compare Source

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.

`v3.6.1`

This is a fast-track release to replace a broken release 3.6.0 that occurred during the Scala 3.6.0-RC1 release. It might contain bugs that would be have been fixed during the Release Candidate bugfixes period. We recommend waiting for the stable Scala 3.6.2 release.

Scala 3.6.0 should never be used to produce libraries. TASTy files produced by this version of the compiler are produced in the experimental mode. These outputs are not compatible with consumers using stable versions of the compiler.

See details in Scala 3.6.0 Post Mortem blogpost
