Notable Changes

Breaking changes

Platforms

Tooling

  • The REPL now has a :doc command to show documentation #4669
  • The REPL has a new and more reliable syntax highlighter #5137
  • The REPL now supports initial and cleanup commands #4933
  • The IDE experience has been improved in various ways: #5133, #5128, #5123, #4304, #5057
  • The VSCode plugin now uses the official scala-lang syntax highlighting plugin #5105

Language

  • Match Types are the latest attempt at solving type-level programming, their semantic is still in flux #4964
  • Tail-recursive methods can now be polymorphic #5112
  • Name-based unapplySeq is now supported #5078
  • Several improvement and addition to Macros and the Tasty reflect API #5189, #4991, #4976, #4904, #4895, #4887, #4896, #4894, #4856, #4874, #4823, #4859, #4822, #4780
  • Proof of concept: Macro based string interpolator #5096
  • Documentation can now be generated from TASTY files, this means we can generate documentation without retypechecking the entire project. It is the first step toward making documentation generation incremental #4789
  • Experimental support for generic Tuples has been implemented #4938
  • Label defs have been replaced by labelled blocks #5056, #4982, #5113
    • This fixes some long-standing issues with pattern matching, including stack overflows in the compiler with big pattern matches
    • It also makes it much easier for the (in progress) Scala.JS backend to output Javascript, since Javascript does not have goto but does have break.
  • The experimental local optimizations phases have been removed #4799

As well as many bug fixes and other improvements!
