What's new in this version:

Collections:
- Faster Vector concatenation
- New LinkedHashMap/LinkedHashSet implementation

Compatibility:
- Support JDK 20 and 21 by upgrading to ASM 9.5
- Fix crash reading JDK 21 classfiles
- Support Java 17 sealed in Java sources and classfiles
- Support Scala 3.3 in TASTy reader

Align with Scala 3:
- Accept implicit _, implicit (x: Int) in lambdas, like Scala 3 does
- Deprecate infix type args, as they are dropped in Scala 3
- Allow eta-expansion of methods with dependent types
- Abstract parent copy does not suspend case copy
- Don't GLB binders of type patterns, use the type directly
- Under -Xsource:3, warn that inherited members no longer take precedence over outer definitions in Scala 3
- Under -Xsource:3, adjust 2.13.9 change to ignore override type for whitebox macro expansion
- Under -Xsource:3, use narrowest type for pt of override
- Under -Xsource:3, warn about change to parenless lambda parens

Lints and warnings:
- Lint select from Unit, or Int that incurs widening
- Lint for integral divisions that are widened to a float
- Lint if args adapted to Unit and discarded
- Warn that implicit should have explicit type

Other notable changes:
- Disallow mixins where super calls bind to vals
- Make scalac's argument-file processing more like javac's in handling spaces and line breaks
- Bump JLine and JNA versions
- javabootclasspath supersedes jrt
- Report total errors on stderr
- Fix pathologically slow compilation of some pattern matches since 2.13.7
- Provide equals and hashCode on IterableWrapper again (fixing 2.13.9 regression)
- Improvements to -Vimplicits; errors now show complete implicit search tree
- -Vprint defaults to -Vprint:typer; phases may be prefixed with ~ to mean "before and after"
