ScalaSTM - 0.6-SNAPSHOT RELEASE NOTES
There are currently no changes between 0.5 and 0.6-SNAPSHOT.
Snapshot releases deployed to the scala-tools.org repository are tested
and functional, but may have changing APIs.
----
Changes between 0.4 and 0.5:
* Added scala.concurrent.stm.japi.STM, which makes it much cleaner to
access ScalaSTM functionality from Java.
----
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.
----
Changes between 0.2 and 0.3:
* Support for Scala 2.9.0.RC1.
* Bug fixes (see https://github.com/nbronson/scala-stm/issues/closed ).
* Timeouts for modular blocking. Set timeouts at the atomic block using
atomic.withRetryTimeout, or at the retry site using retryFor.
----
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 #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).
