Ladies and gentlemen,
We, the Akka committers, are proud to announce the availability of Akka 2.0 RELEASE CANDIDATE 1 — the next generation of Akka!
Building on the experiences from the Akka 1 series, we take Akka to the next level — resilience by default, scale up and out by configuration, extensibility by design and with a smaller footprint.

Highlights of Akka 2.0 RELEASE CANDIDATE 1:
* 26 tickets closed in 8 days (190 files changed, 3765 insertions(+), 2041 deletions(-))
* Docs
– Http documentation updated
– Java documentation for 0MQ module
– JMM docs regarding Akka Futures
– Minor edits overall
* Routing
– Erronous resize resolved in Resizers
* Dispatchers
– BalancingDispatcher now has a config option for "attempt-teamwork"
– BalancingDispatcher race condition resolved
* Futures
– Future.blocking() now has a Java API in Futures.blocking()
– Future.blocking() now doesn't require an ExecutionContext
* Config
– Updated to latest HOCON version (configs are now Serializable)
– Added setting for shutting down the JVM on fatal problems (jvm-exit-on-fatal-error)
– Serializer config has changed to be more convenient for the best–effort search
Highlights of Akka 2.0 Milestone 4:
* 57 tickets closed in 13 days. (447 files changed, 20231 insertions(+), 15202 deletions(-))
* Docs
– Akka now has 337 pages of documentation (vs. 305 in M3) Available both as html and as pdf.
* Actor
– Default dispatcher based on new ForkJoinPool destined for Java8, extremely better scalability.
– ActorPath.fromString — easier creating of ActorPaths
– Remove FSM Ev()
* Futures
– Brand new Java API supporting all operations on Future
– Future.recoverWith — the "flatMap" of "recover"
– Future.fallbackTo — the harmonized name of what was previously or/orElse
– Promise.complete — now throws an IllegalStateException if already completed, use tryComplete for conditional complete
– Future.andThen — makes it possible to create ordered asynchronous side effects
– All callbacks are now friendlier to the type inferencer
* Remote
– Read timeout tracking now supports read timeouts, write timeouts and both, and can be turned off completely
– No need to configure nodename anymore
* Serialization
– Serialization now supports best–effort lookup of suitable Serializer, see docs for more info
* Misc
– Better Android compatibility
– Lots of minor bugfixes
– Lots of small performance improvements
– Reworked class loading strategy to be more unified
Highlights of Akka 2.0 Milestone 3:
* Almost 90(!) tickets closed in 3 weeks. (505 files changed, 13617 insertions(+), 8636 deletions(-))
* Docs – Akka now has 305 pages of documentation (vs. 254 in M2) Available both as html and as pdf.
* Patterns
– "Ask/?" being moved out to a Pattern" — for Scala add 'import akka.pattern.ask' (which will provide suitable implicit conversions to support nearly the same methods, check with 'import akka.migration.ask' first for deprecations; and for Java use akka.pattern.Patterns.ask().
– gracefulStop
– pipeTo
* Actor
– Removed timeout from Props
– Removed FaultHandler from Props
– Renamed FaultHandler to SupervisorStrategy to be more clear
– Improved SupervisorStrategy creation and parametrization
* ActorSystem
– ActorSystemImpl renamed to ExtendedActorSystem for Extensions
– Now has awaitTermination
– Can now be configured to only create threads that are daemons
* TypedActor
– TypedActorProps that is used with typedActorOf, instead of overloading
– Possibility to proxy any ActorRef (think Remote etc)
* Futures
– "orElse" is replaced with "or"
– "zip" has been added
– Reduced memory footprint per Future
* Remote
– Support for starting up Akka on a randomly chosen port
– Lots of optimizations
* Akka STM
– Now uses ScalaSTM instead of Multiverse directly
* IOActor
– Many improvements for 2.0
* Routers
– Custom Routers (create your own!)
– Remote Routers, any Router can now be remote
– Resizers, replaces the old Actor Pool API, add Resizer to Router to get Actor Pool functionality
– Resizers, configure them in config file
– Resizers, also usable from Java, so now there's a Java API for "Actor Pools"
* ømq
– This module is now ported from Akka 1.3 for Scala
* Akka FSM
– There is now documentation on how to use Akka FSM from Java!
* Migration
– We now have a draft of a migration package that will help you from 1.x to 2.0, try it out and give us feedback
And much, much more!
Highlights of Akka 2.0 Milestone 2:
* 70 closed tickets since M1
* More documentation, 254 pages vs 216 for M1
– Serialization API
– EventBus API
– Agents
– Dead Letters
– General docs improvements
* More samples (Remoting etc)
* Remoting
– Remote Death Watch
– Improved logging
– Improved performance
– More configuration options
* Routers
– Load from config
– BroadcastRouter
* Decoupled Futures from Dispatchers, use any old ExecutorService or Executor
* Akka now uses Scala STM
* Improved Java APIs
* Many minor improvements, bugfixes and tweaks
Highlights of Akka 2.0 Milestone 1:
* Asynchronous by design — most actor related operations are now asynchronous
* Removing all global state — introducing ActorSystem
* Mandatory Parental Supervision — fault-tolerant default and automatic
* Remote Supervision — children spawned on other nodes are supervised
* Actor Tree Hierarchy — file-system like addressing, with wildcards etc.
* Props — Actor configuration is immutable, sharable and reusable
* Futures & Promises — simpler and more powerful, blocking API refactored out
* Actor Routing — completely revamped, load balancing made much simpler
* Death Watch — react to the death of any actor
* Typed Actors — 0 dependency JDK Proxy based implementation
* EventBus API — publish-subscribe to anything you want
* Extensions — add new functionality to Akka
* Pluggable remote transport layer — Netty/TCP built–in
* General API unification and simplification — less to remember
* Simpler actor life-cycle semantics and management
* Slimmer footprint — around 2.7 million Actors per GB of memory
* Lots of performance and scalability improvements
Akka is released under the Apache V2 license.
