v2.11.12: Scala 2.11.12

Compare Source

Scala 2.11.12 is a maintenance release to allow running Scala 2.11 tooling on Java 9. Five pending backports were merged.

This release addresses (#​6108) a privilege escalation vulnerability that was identified in the Scala compilation daemon CVE-2017-15288.

We strongly encourage you to upgrade to the latest stable version of Scala 2.12.x, as the 2.11.x series is no longer actively maintained.

There is a known bug on Java 9 involving the repl: the workaround is to launch it as scala -nobootcp.

More general information about the Scala 2.11 series is available in the release notes for Scala 2.11.1.

Thanks to Lightbend for their continued sponsorship of the Scala core team’s efforts. Lightbend offers commercial support for Scala.

v2.11.11: Scala 2.11.11: all the way to eleven!

Compare Source

The 2.11.11 release concludes the 2.11.x series, with no further releases planned. Please consider upgrading to 2.12!

Do not use 2.11.9 or 2.11.10, which introduced significant regressions (see below). This also means this series goes to eleven. (No further, though.)

Changes

Significant changes since 2.11.8 include:

• #​5730, #​5846 Allow custom apply and unapply methods in case class companions. Also allows case class constructors and apply methods to be private. (In 2.11.11, -Xsource:2.12 is needed to enable these changes. In Scala 2.12.2, they are on by default.)
• #​5343 Add support for higher order unification under -Ypartial-unification (SI-2712)
• #​5341 Fix for higher-kinded GADT refinement
• #​5061 JMH-based benchmark framework for contributors
• #​5026 Upgrade to newer scala-xml (1.0.5)

2.11.11 resolves regressions introduced in 2.11.9 and 2.11.10: #​5730 (fixed by #​5828 and #​5846), #​5664 (fixed by #​5821). Special thanks to @​xuwei-k and @​sjrd for reporting and helping diagnose these.

For more information, check out all closed bugs and merged PRs.

As usual for minor releases, Scala 2.11.11 is binary compatible with the whole Scala 2.11 series (with the exception of 2.11.9, which should not be used to publish artifacts, see #​5821).

Scala 2.11 Notes

The release notes for Scala 2.11.0 have important information applicable to the whole 2.11 series.

Obtaining Scala

Scala releases are available through a variety of channels, including (but not limited to):

• Bump the scalaVersion setting in your sbt-based project
• Download a distribution from scala-lang.org
• Obtain JARs via Maven Central

v2.11.10: [Do not use] Scala 2.11.10, please upgrade to 2.11.11

Compare Source

Not suitable for use due to a regression caused by #​5730, fixed in 2.11.11 by #​5846.

v2.11.9: [Do not use] Scala 2.11.9, please upgrade to 2.11.11

This release contains a binary incompatible change introduce by #​5664 and fixed by the reversion in #​5821, which is available in 2.11.11 (yes, 2.11.10 was also flawed).

v2.11.8: Scala 2.11.8

Compare Source

We are pleased to announce the availability of Scala 2.11.8!

Significant changes since 2.11.7 include:

• The Scala REPL now has robust and flexible tab-completion (details below)
• An assortment of bugs have been fixed

Compared to 2.11.7, this release resolves 44 issues. We merged 175 pull requests.

As usual for minor releases, Scala 2.11.8 is binary compatible with other releases in the Scala 2.11 series.

The last planned 2.11.x release will be 2.11.9 in late 2016.

New tab-completion in the Scala REPL

The implementation of tab-completion in the Scala REPL has been rewritten and now uses the same infrastructure as for example Scala IDE and ENSIME.

There are a number of improvements:

• Reliable completion, also in partial expressions and syntactically incorrect programs: try class C { def f(l: List[Int]) = l.<TAB>
• CamelCase completion: try (l: List[Int]).rro<TAB>, it expands to (l: List[Int]).reduceRightOption
• Show desugarings performed by the compiler by adding //print: try for (x <- 1 to 10) println(x) //print<TAB>
• Complete bean getters without typing get: try (d: java.util.Date).day<TAB>
• Find members by typing any CamelCased part of the name: try classOf[String].typ<TAB> to get getAnnotationsByType, getComponentType and others
• Complete non-qualified names, including types: try def f(s: Str<TAB>
• Press tab twice to see the method signature: try List(1,2,3).part<TAB>, which completes to List(1,2,3).partition; press tab again to display def partition(p: Int => Boolean): (List[Int], List[Int])

Thanks to @​retronym and @​som-snytt for their fruitful collaboration on this work!
