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.
Implement quickfixes, aka actionable diagnostics (via CodeAction) (#10406 by @eed3si9n)
Add -quickfix compiler option to apply quickfixes to source files (#10482 by @lrytz)
Add quickfixes to some warnings and errors (#10484 by @lrytz)
Align with Scala 3
Emit migration warnings under -Xsource:3 as fatal warnings, not errors; -Xmigration disables fatality (#10439 by @som-snytt, #10511)
As usual for our minor releases, Scala 2.13.12 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.
