Open dependabot[bot] opened this issue 4 years ago • 0 comments

Bumps scala-compiler from 2.12.2 to 2.12.4.

Release notes

Sourced from scala-compiler's releases.

Scala 2.12.4

Our benchmarks show a further 5–10% reduction in compile times since 2.12.3.

Improved Java 9 friendliness, with more to come!

#6097 Fix runtime reflection of empty package members under Java 9

#6098 Adapt to change in Java 9 classloader hierarchy

This release addresses (#6120) a privilege escalation vulnerability that was identified in the Scala compilation daemon CVE-2017-15288.

We'd like to highlight a few of the excellent contributions by @hrhino and @TomasMikula, previewing 2.13 improvements (available now under -Xsource:2.13):

#5867 Include the parts of a compound/refinement type in implicit scope

#6074 Resolve implicit instances for abstract types, according to the spec

#6069 Higher-kinded type variable unification

For Spark, with love:

#6101 Make Lazy* classes serializable

Preparing for simplification of named arguments in 2.13:

#6089 Deprecate assignments in argument position

Rather than pollute /tmp,

#6120 Move compilation daemon portfile under ~/.scalac/

For more details, check out all closed bugs and merged PRs.

As usual for minor releases, Scala 2.12.4 is binary compatible with the whole Scala 2.12 series.

Bump the scalaVersion setting in your sbt-based project

Scala 2.12.3

Changes

Compiler performance has improved significantly and is now automatically benchmarked after each change.

A new optimizer setting -opt-inline-from limits the classes from which the inliner will copy code. scalac -opt-inline-from:help provides detailed help.
