With the Scala 2.9.0 RC3 now available and the release page http://www.scala-lang.org/node/7285 describing the great features that were added in that release, does anyone know what we can expect in 2.10 and future releases?

The best that page does is tease us with noting that there are some "teaser papers" will appear in this year's Onward! conference and in GPCE http://onward-conference.org/2011/

Scala 2.9.0.Final is available, to be more precise. –  Daniel C. Sobral May 21 '11 at 3:43
Thanks Daniel for pointing that out! –  Dakotah North May 23 '11 at 15:16

Some of the slides and videos from Scala Days 2011 are online at https://wiki.scala-lang.org/display/SW/ScalaDays+2011+Resources . The day one (June 2nd) keynote by Martin Odersky on the state of Scala may be of interest.

I'd be inclined to ask on their mailing list! Some observations:

  • Scala is in danger of becoming a Kitchen Sink of language features, this is not necessarily a good thing.

  • Scala's dynamic capabilities will be enhanced as the language folks figure out 'cool stuff' they can do with invokedynamic and MethodHandle coming into JDK7 (and therefore the JVM).

  • Speed! Watch as they take advantage of the JRockit merge and Hotspot improvements.

  • I expect to see the 3 'levels' of Scala start to be built into the language/compiler/whatever so that large development teams can use the smaller subset of the language as opposed to the 10,000 meters of rope that they can currently hang themselves with.

Meh, I don't actually really know :)

+1: "Scala is in danger of becoming a Kitchen Sink of language features". I am a big fan of Scala but I agree with your observation. I think every language should eventually be frozen and development effort should be put on libraries, tools, frameworks. IMO Scala as a language is already very rich (and complex). –  Giorgio May 25 '13 at 9:27

See http://stackoverflow.com/questions/5966068/scala-roadmap-post-2-9-0 for some answers, including STM, parallelization improvements, improved binary compatibility, more type-safe equality.
