Scala 2.12 and the road towards 3.0
summary
Scala 2.12 is Java 8 only and compiles traits directly to interfaces, using invokeDynamic for lambdas and a rewritten ASM backend, which cuts example jars from about 15MB to 9MB. The project doubles monthly downloads to over a million, ships roughly one release every six weeks, moved issue work from Jira to GitHub, runs a community build for compatibility checks, modularizes the compiler and libraries, and lays out milestones 2.13 → 2.14 → 3.0 with collection and macro rewrites.
