0.10.0-RC1

Blog post with more details on the release: http://dotty.epfl.ch/blog/2018/10/10/10th-dotty-milestone-release.html

Notable Changes

Breaking changes

• We now require sbt 1.2.3 and sbt-dotty 0.2.4, see https://github.com/lampepfl/dotty-example-project

Platforms

• Java 9+ is now supported #5175, #5166, #3138
• Our Windows support has been improved #5130, #5171, #5179, #5170, #5156, #5125, #5085
• Compiling using the 2.13 standard library is almost here #4807
• Using mill instead of sbt is now possible, though still considered experimental: https://github.com/lampepfl/dotty-example-project/tree/mill

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• Label defs have been replaced by labelled blocks #5056, #4982, #5113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!
