Announcing the Release of Scala 2.10.3

Yesterday, the Scala team proudly announced the release of Scala 2.10.3, available for download from scala-lang.org or from Maven Central! This release marks the final in the 2.10.3-RC series, the team and contributors fixing 50 issues since 2.10.2! Since 2.10.3 is strictly a bug-fix release, here’s an brief overview of the most prominent new features and improvements as introduced in 2.10.0:

• Value Classes
  • A class may now extend AnyVal to make it behave like a struct type (restrictions apply).
  • http://docs.scala-lang.org/overviews/core/value-classes.html
• Implicit Classes
  • The implicit modifier now also applies to class definitions to reduce the boilerplate of implicit wrappers.
  • http://docs.scala-lang.org/sips/pending/implicit-classes.html
• String Interpolation

  • val what = "awesome";
    println(s"string interpolation is ${what.toUpperCase}!")

  • http://docs.scala-lang.org/overviews/core/string-interpolation.html
• Futures and Promises
  • Asynchronously fetch some JSON in Play Framework:

    for (
      req <- WS.url(restApiUrl).get()
    ) yield (req.json \ "users").as[List[User]]

  • http://docs.scala-lang.org/overviews/core/futures.html

 This is just a snippet of a long list of updates; head over to Scala-lang.org for more details on the announcement and a big thank you to all contributors!
