Akka.NET v1.3.14 Stable Release

1.3.14 July 29 2019

Maintenance Release for Akka.NET 1.3
You know what? We're going to stop promising that this is the last 1.3.x release, because even though we've said that twice... We now have another 1.3.x release.

1.3.14 consists of non-breaking bugfixes and additions that have been contributed against the Akka.NET v1.4.0 milestone thus far. These include:

• Akka.Cluster.Sharding: default "persistent" mode has been stabilized and errors that users have ran into during ShardCoordinator recovery, such as Exception in PersistentShardCoordinator ReceiveRecover;
• Akka.Remote: no longer disassociates when serialization errors are thrown in the remoting pipeline - the connection will now stay open;
• Akka.Cluster.Tools: mission-critical ClusterClient and ClusterClientReceptionist fixes;
• SourceLink debugging support for Akka.NET; and
• Akka.Persistence: Allow AtLeastOnceDelivery parameters to be set from deriving classes;
• Akka.Persistence.Sql: BatchingSqlJournal now preserves Sender in PersistCallback; and
• Akka: bugfix - coordinated shutdown timesout when exit-clr = on.

Akka.NET v1.4.0-beta1 Release

1.4.0-beta1 July 17 2019

First pre-release candidate for Akka.NET 1.4
Akka.NET v1.4 has a ways to go before it's fully ready for market, but this is the first publicly available release on NuGet and it contains some massive changes.

• Akka.Cluster.Sharding's default "persistent" mode has been stabilized and errors that users have ran into during ShardCoordinator recovery, such as Exception in PersistentShardCoordinator ReceiveRecover
• StreamRefs have been added to Akka.Streams, which allows streams to run across process boundaries and over Akka.Remote / Akka.Cluster.
• Akka.NET now targets .NET Standard 2.0, which means many annoying polyfills and other hacks we needed to add in order to support .NET Core 1.1 are now gone and replaced with standard APIs.
• Lots of small bug fixes and API changes have been added to Akka core and other libraries.

To follow our progress on the Akka.NET v1.4 milestone, click here.

We expect to release more beta versions in the future, and if you wish to get access to nightly Akka.NET builds then click here.

Akka.NET v1.3.11 Stable Release

1.3.11 December 17 2018

Maintenance Release for Akka.NET 1.3

Akka.NET v1.3.11 is a bugfix patch primarily aimed at solving the following issue: DotNetty Remote Transport Issues with .NET Core 2.1.

.NET Core 2.1 exposed some issues with the DotNetty connection methods in DotNetty v0.4.8 that have since been fixed in subsequent releases. In Akka.NET v1.3.11 we've resolved this issue by upgrading to DotNetty v0.6.0.

In addition to the above, we've introduced some additional fixes and changes in Akka.NET v1.3.11:

• Akka.FSharp: Akka.Fsharp spawning an actor results in Exception
• Akka.Remote: tcp-reuse-addr = off-for-windows prevents actorsystem from starting
• Akka.Remote: tcp socket address reuse - default configuration
• Akka.Cluster.Tools:
  Actor still receiving messages from mediator after termination
• Akka.Persistence: Provide minSequenceNr for snapshot deletion

Akka.NET v1.3.9 Stable Release

1.3.9 August 22 2018

Maintenance Release for Akka.NET 1.3

Akka.NET v1.3.9 features some major changes to Akka.Cluster.Sharding, additional Akka.Streams stages, and some general bug fixes across the board.

Akka.Cluster.Sharding Improvements
The Akka.Cluster.Sharding documentation already describes some of the major changes in Akka.NET v1.3.9, but we figured it would be worth calling special attention to those changes here.

Props Factory for Entity Actors

In some cases, the actor may need to know the entityId associated with it. This can be achieved using the entityPropsFactory parameter to ClusterSharding.Start or ClusterSharding.StartAsync. The entity ID will be passed to the factory as a parameter, which can then be used in the creation of the actor.

In addition to the existing APIs we've always had for defining sharded entities via Props, Akka.NET v1.3.9 introduces a new method overload for Start and StartAsync which allows users to pass in the entityId of each entity actor as a constructor argument to those entities when they start.

For example:

var anotherCounterShard = ClusterSharding.Get(Sys).Start(
	                        typeName: "AnotherCounter",
	                        entityProps: Props.Create<AnotherCounter>(),
	                        typeName: AnotherCounter.ShardingTypeName,
	                        entityPropsFactory: entityId => AnotherCounter.Props(entityId),
	                        settings: ClusterShardingSettings.Create(Sys),
	                        extractEntityId: Counter.ExtractEntityId,
	                        extractShardId: Counter.ExtractShardId);

This will give you the opportunity to pass in the entityId for each actor as a constructor argument into the Props of your entity actor and possibly other use cases too.

Improvements to Starting and Querying Existing Shard Entity Types
Two additional major usability improvements to Cluster.Sharding come from some API additions and changes.

The first is that it's now possible to look up all of the currently registered shard types via the ClusterSharding.ShardTypeNames property. So long as a ShardRegion of that type has been started in the cluster, that entity type name will be added to the collection exposed by this property.

The other major usability improvement is a change to the ClusterSharding.Start property itself. Historically, you used to have to know whether or not the node you wanted to use sharding on was going to be hosting shards (call ClusterSharding.Start) or simply communicated with shards hosted on a different cluster role type (call ClusterSharding.StartProxy). Going forward, it's safe to call ClusterSharding.Start on any node and you will either receive an IActorRef to active ShardRegion or a ShardRegion running in "proxy only" mode; this is determined by looking at the ClusterShardingSettings and determining if the current node is in a role that is allowed to host shards of this type.

• Akka.Cluster.Sharding: Sharding API Updates
• Akka.Cluster.Sharding: sharding rebalance fix
• Akka.Cluster.Sharding: log formatting fix
• Akka.Cluster.Sharding: RestartShard escapes into userspace

Akka.Streams Additions and Changes
In Akka.NET v1.3.9 we've added some new built-in stream stages and API methods designed to help improve developer productivity and ease of use.

• Akka.Streams: add CombineMaterialized method to Source
• Akka.Streams:
  KillSwitches: flow stage from CancellationToken
• Akka.Streams: Port KeepAliveConcat and UnfoldFlow
• Akka.Streams: Port PagedSource & IntervalBasedRateLimiter

Other Updates, Additions, and Bugfixes

• Akka.Cluster: cluster coordinated leave fix for empty cluster
• Akka.Cluster.Tools: bumped ClusterClient message drop log messages from DEBUG to WARNING
• Akka.Cluster.Tools: Singleton - confirm TakeOverFromMe when singleton already in oldest state
• Akka.Remote: RemoteWatcher race-condition fix
• Akka: fix concurrency bug in CircuitBreaker
• Akka: Fixed ReceiveTimeout not triggered in some case when combined with NotInfluenceReceiveTimeout messages
• Akka.Persistence: Optimized recovery
• Akka.Persistence: Allow persisting events when recovery has completed

Akka.NET v1.3.8 Stable Release

1.3.8 June 04 2018

Maintenance Release for Akka.NET 1.3

Akka.NET v1.3.7 is a minor patch consisting mostly of bug fixes as well as an upgrade to DotNetty v0.4.8.

DotNetty v0.4.8 Upgrade
You can read the release notes for DotNetty v0.4.8 here - but here are the major improvements as they pertain to Akka.NET:

1. DotNetty length-frame decoding is now fully-supported on .NET Core on Linux and
2. Socket shutdown code has been improved, which fixes a potential "port exhaustion" issue reported by Akka.Remote users.

If you've been affected by either of these issues, we strongly encourage that you upgrade your applications to Akka.NET v1.3.8 as soon as possible.

Updates and Additions

1. Akka.Streams: add PreMaterialize support for Sources
2. Akka.Streams: add PreMaterialize support for Sinks
3. Akka.Streams:
   Port Pulse, DelayFlow and Valve streams-contrib stages
4. Akka.FSharp: Unit test Akka.FSharp.System.create with extensions

Relevant documentation for Akka.Streams pre-materialization, for those who are interested: http://getakka.net/articles/streams/basics.html#source-pre-materialization

Bugfixes

1. Akka.Remote: ActorSelection fails for ActorPath from remotely deployed actors
2. Akka.Remote: WilcardCard ActorSelections that fail to match any actors don't deliver messages into DeadLetters
3. Akka.Cluster: SplitBrainResolver logs "network partition detected" after change in cluster membership, even when no unreachable nodes
4. Akka: SynchronizationLockException in user-defined mailboxes
5. Akka: UnhandledMessageForwarder crashes and restarted every time the app is starting

Akka.NET v1.3.7 Stable Release

1.3.7 May 15 2018

Maintenance Release for Akka.NET 1.3

Akka.NET v1.3.7 is a minor patch consisting mostly of bug fixes.

DotNetty stabilization
We've had a number of issues related to DotNetty issues over recent weeks, and we've resolved those in this patch by doing the following:

• Locking down the version of DotNetty to v0.4.6 until further notice
• Resolving memory leaks introduced with DotNetty in v1.3.6

We will be upgrading to DotNetty v0.4.8 in a near future release, but in the meantime this patch fixes critical issues introduced in v1.3.6.

Bugfixes

1. Akka.Persistence.Sql: Slow reading of big snapshots - this will require a recompilation of all Akka.Persistence.Sql-type Akka.Persistence plugins.
2. Akka.Fsharp: spawning an actor results in Exception in 1.3.6 release

See the full list of fixes for Akka.NET v1.3.7 here.
