Scala 2.12.0-M3 is now available for download and on maven central.
We would like to highlight the following changes since M2:
* The REPL received a robust and flexible implementation of tab-completion (also coming to 2.11.8 in a few weeks)
* The @implicitAmbiguous annotation allows customizing the error message when an implicit search finds multiple ambiguous values
* The optimizer now attempts to inline invocations of higher-order methods if the argument function is statically known, eliminating polymorphic callsites
Best,
Lukas
