Scala 2.13 is getting closer and closer!
We've been polishing the improved and simplified Scala collections library that first shipped in 2.13.0-M4. We expect the API to remain stable now, though there may still be minor changes in RC1.
M5 is our feature-freeze release for 2.13. From here forward, we’ll close existing open loops but not embark on or accept new work.
The major collections changes already landed in M4. See the M4 release notes for a summary.
(excerpts from emails I sent my co-workers at Northwestern University)
Did some reading on Scala, Groovy, and JRuby. I'm interested in adding another language to the devel team's repertoire, a JVM-based language that interoperates smoothly with Java code so we could write new code in the new language without being forced to change existing code. I'm particularly interested in having a more powerful language than Java to use for
