* This can't go into 2.2.x since ScalaTest 1.9.2-SNAP2 has source incompatible changes and the dependecy in akka-multi-node-node-testkit would force people to upgrade.
* UnreachableNodeJoinsAgain failed because of gated connection
* Removed default test value of retry-gate-closed-for, instead
default from reference.conf is used, i.e. 0s
* deadLetters logging love
* Rename config akka.event-handlers to akka.loggers
* Rename config akka.event-handler-startup-timeout to
akka.logger-startup-timeout
* Rename JulEventHandler to JavaLogger
* Rename Slf4jEventHandler to Slf4jLogger
* Change all places in tests and docs
* Deprecation, old still works, but with warnings
* Migration guide
* Test for the deprecated event-handler config
* Change build to propagate all system properties starting with 'akka.'
to multi-jvm and multi-node tests.
* Adjusted AkkaSpec and MultiNodeSpec to use load of the config, which
means that default overrides (system properties) are used.
* Improved DurableMailboxSpec for stand alone usage
* Changed build to publish DurableMailboxSpec in akka-mailboxes-common-test
* Changed documentation of durable mailboxes and added full example of
how to implement a durable mailbox, with test
- LoggingBus.startDefaultLoggers will register a forwarder actor for
UnhandledMessage, which republishes them as Debug message
- add tests and docs
- TestEventListener logs UnhandledMessage as Warning
* ActorTimeout (akka.actor.timeout) was used to all sorts of things.
* TestKit default-timeout
* TypedActor timeout for non void methods
* Transactor coordinated-timeout
* ZeroMQ new-socket-timeout
* And in various tests
* Changed signatures and constructor of MessageDispatcherConfigurator
* Changed Dispatchers.lookup, keep configurators instead of dispatchers
* Removed most of the Dispatchers.newX methods, newDispatcher is still there because of priority mailbox
* How should we make it easy to configure priority mailbox?
* Changed tons tests
* Documentation and ScalaDoc is not updated yet
* Some tests in ActorModelSpec are temporary ignored due to failure
