ScalaSTM - 0.5

Changes between 0.4 and 0.5:
* Added scala.concurrent.stm.japi.STM, which makes it much cleaner to
  access ScalaSTM functionality from Java.

ScalaSTM - 0.4

Changes between 0.3 and 0.4:
* CommitBarrier added, which allows multiple atomic blocks (each on its
  own thread) to commit together.
* Small performance improvements.
* STMBench7 benchmark support added.
* Automatic selection of STMImpl in most cases.

Release 0.3

* Timeouts for retry
* Support for 2.9.0.RC1
* Bug fixes

ScalaSTM - 0.2 RELEASE NOTES

Changes between 0.1 and 0.2:

* Substantial performance improvements, especially for nested atomic
  blocks.

* TSet.View and TMap.View are integrated into the Scala collection
  class hierarchy, with factory companion objects and Builder and
  CanBuildFrom instances.

* A fix for whileCommitting handlers (issue scala-stm#3).

* TxnLocal can now be read and written from while-preparing and while-
  committing handlers.  Combining TxnLocal and life-cycle handlers is
  now more concise.

* Transaction statistics can be enabled for the default algorithm
  with the VM argument -Dccstm.stats=1 (details in the ScalaDoc for
  scala.concurrent.stm.ccstm.CCSTM).

Initial non-snapshot release. Includes

* the pluggable ScalaSTM API
  - foundational types: Ref, TArray
  - operations: atomic, orAtomic, retry
  - integrated concurrent collections: TMap, TSet

* CCSTM as a reference implementation
