The fifth development milestone of Scala 2.11 brings the following goodness:
- Pattern matcher: extractors became name-based thanks to @paulp (#2848)
- @adriaanm continues his modularization effort: scala.xml and scala.util.parsing live in separate repositories now (#2855)
- more bits of experimental backend based on ASM by @magarciaEPFL (#2711)
- improvements to stacktrace printing in REPL by @som-snytt and @qerub (#2877 and #2824)
- clarification of Scala license (#2881)
Scala was released with slightly modified variant of 3-clause BSD license. The fact that this is not exactly 3-clause BSD license was causing problems for people adopting Scala because they would have to go through legal process that approves a new license in their organization.
We've clarified the situation but switching to standard wording of 3-clause BSD license. The intent and meaning of the license hasn't change because previous version was just reworded version of 3-clause BSD license.
Scala compiler artifact (due to scaladoc) depends on previous version (2.11.0-M4) of
scala-parser-combinators modules. If you depend on
scala-compiler (e.g. your are a macro writer) then you need to use extra care when upgrading to M5. See scala-partest#3 which discusses the problem in depth and offers a work-around for sbt-based builds.
When reporting a bug, please set the 'Affects Version' field to 2.11.0-M5 and add the
regression label where appropriate.
