Looks like the announcement is still under work, e.g. you can visit 2.12.0-RC1 page [1] and 2.12.0-RC2 [2] but not 2.12.0 [3] yet, and both http://get-scala.org and http://scala-lang.org homepages point to 2.11.8 as the official version.

BTW, here's a list of packages available for 2.12.x [4], if you are planning to migrate (please do!). The package is on Maven [5] :-)

From the release notes [6] "This release is identical to 2.12.0-RC2" so anything on RC2 should just work.

BTW "2.12.1 will be out shortly (by the end of November) to address some known (but rare) issues in 2.12.0, and 2.11.9 is the last planned 2.11.x release (due by mid December). In the next few weeks, we at Lightbend will share our plans for Scala 2.13." [4]

Any news on the performance impact of the new trait encoding [1] , [2]? [1] http://www.scala-lang.org/blog/2016/07/08/trait-method-perfo... [2] https://bugs.openjdk.java.net/browse/JDK-8161334

If I remember correctly, for 2.12 the compiler will generate additional forwarder methods, which mitigates the performance issues, but increases file size again.

It's still a lot smaller than 2.11, but for instance the standard library of 2.12.0-RC1 was 900kB smaller than 2.12.0.
