Scala 2.12 roadmap | The Scala Programming Language

Scala 2.10.5 (Q4 2014) will be the last 2.10 release. Were planning five 2.11.x releases in 2014, and a few more in 2015 (were still deciding on when to EOL 2.11.x). At Typesafe, 2.12 development will begin with infrastructure work in Q4 2014, with our development focus shifting to 2.12 in 2015.
