Scala 2.10.1 is now available!

March 13, 2013

We are very happy to announce the final release of Scala 2.10.1!

The Scala team and contributors fixed 166 issues since 2.10.0!

In total, 242 RC1 pull requests, 7 RC2 pull requests, and 4 RC3 pull requests were opened on GitHub, of which 94.5% were merged after having been tested and reviewed.

Known Issues

Before reporting a bug, please have a look at these known issues.

Scala IDE for Eclipse

The Scala IDE with Scala 2.10.1-RC3 built right in is available through one of the following update-sites:

for Eclipse 3.7 (Indigo)
for Eclipse 3.8/4.2 (Juno) (Support for this version is experimental.)

Have a look at the getting started guide for more info.

New features in the 2.10 series

Since 2.10.1 is strictly a bug-fix release, here's an 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 get some JSON: for (req <- WS.url(restApiUrl).get()) yield (req.json \ "users").as[List[User]] (uses play!)
- http://docs.scala-lang.org/overviews/core/futures.html
Dynamic and applyDynamic
- x.foo becomes x.applyDynamic("foo") if x's type does not define a foo, but is a subtype of Dynamic
- http://docs.scala-lang.org/sips/pending/type-dynamic.html
Dependent method types:
- def identity(x: AnyRef): x.type = x // the return type says we return exactly what we got
New ByteCode emitter based on ASM
- Can target JDK 1.5, 1.6 and 1.7
- Emits 1.6 bytecode by default
- Old 1.5 backend is deprecated
A new Pattern Matcher
- rewritten from scratch to generate more robust code (no more exponential blow-up!)
- code generation and analyses are now independent (the latter can be turned off with -Xno-patmat-analysis)
Scaladoc Improvements
- Implicits (-implicits flag)
- Diagrams (-diagrams flag, requires graphviz)
- Groups (-groups)
Modularized Language features
- Get on top of the advanced Scala features used in your codebase by explicitly importing them.
- http://docs.scala-lang.org/sips/pending/modularizing-language-features.html
Parallel Collections are now configurable with custom thread pools
- http://docs.scala-lang.org/overviews/parallel-collections/overview.html
Akka Actors now part of the distribution
- scala.actors have been deprecated and the akka implementation is now included in the distribution.
- See the actors migration project for more information.
Performance Improvements
- Faster inliner
- Range#sum is now O(1)
- Update of ForkJoin library
- Fixes in immutable TreeSet/TreeMap
- Improvements to PartialFunctions
Addition of ??? and NotImplementedError
Addition of IsTraversableOnce + IsTraversableLike type classes for extension methods
Deprecations and cleanup
- Floating point and octal literal syntax deprecation
- Removed scala.dbc

Experimental features

Scala Reflection
- http://docs.scala-lang.org/overviews/reflection/overview.html
Macros
- http://docs.scala-lang.org/overviews/macros/overview.html

The API is subject to (possibly major) changes in the 2.11.x series, but don't let that stop you from experimenting with them! A lot of developers have already come up with very cool applications for them. Some examples can be seen at http://scalamacros.org/news/2012/11/05/status-update.html.

A big thank you to all the contributors!
