Release notes

Sourced from scala-library's releases.

Scala 2.12.7

Main highlights of this release:

• Add Scaladoc markdown tables (#6043)
• Fix equality of WrappedArray.ofRef (for Spark, #7156)
• Numerous compiler performance improvements (#7067, #6696, #7147)
• Improve performance of HashMaps, Any.## (#7265)

Further highlights:

• Improved Java 9+ support (#7089 ASM 6.2, #7240 Un-deprecate linesIterator)
• Support [**Repeatable**](https://github.com/Repeatable) Java annotations (#6846)
• Support cancellation of batch compilation (#6479)

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

Compiler performance has improved significantly again, and is mostly on par with 2.13. Concretely, you should see a 10% drop in compile times since 2.12.6, according to our compiler benchmarks.

As usual for minor releases, Scala 2.12.7 is binary compatible with the whole Scala 2.12 series.
