v1.3.1 Changes
September 05, 2017🚀 Maintenance Release for Akka.NET 1.3
🛠 Updates and bugfixes:
- 🛠 Bugfix: Hyperion NuGet package restore creating duplicate assemblies for the same version inside Akka
- 📚 Various documentation fixes and updates
- 🛠 Bugfix: issue where data sent via UDP when
ByteStringpayload had buffers with length more than 1,UdpSenderonly wrote the first part of the buffers and dropped the rest. - 🛠 Bugfix: Akka.IO.Tcp failed to write some outgoing messages.
- 👌 Improved support for OSX & Rider
- 🛠 Bugfix: Akka.Persistence support for
SerializerWithStringManifestrequired by Akka.Cluster.Sharding and Akka.Cluster.Tools- Akka.Persistence.Sqlite and Akka.Persistence.SqlServer were unable to support
SerializerWithStringManifest, so using Akka.Cluster.Sharding with Sql plugins would not work.
- Akka.Persistence.Sqlite and Akka.Persistence.SqlServer were unable to support
- 🛠 Bugfix: Akka.Streams generic type parameters of the flow returned from current implementation of Bidiflow's JoinMat method were incorrect.
- 🛠 Bugfix:
PersistenceMessageSerializerwas failing with the wrong exception when a non-supported type was provided.
⚠ Akka.Persistence backwards compability warning:
- ⚡️ Akka.Persistence.Sql introduces an additional field to the schema used by Sql-based plugins to allow for the use of
SerializerWithStringManifestcalledserializer_id. It requires any previous Sql schema to be updated to have this field. Details are included in the Akka.Persistence.Sqlite plugin README.md file. Users of the Akka.Persistence.Sqlite plugin must alter their existing databases to add the fieldserializer_id int (4):
ALTER TABLE {your_event_journal_table_name} ADD COLUMN `serializer_id` INTEGER ( 4 ) ALTER TABLE {your_snapshot_table_name} ADD COLUMN `serializer_id` INTEGER ( 4 ) -
v1.3.0 Changes
August 11, 2017🔋 Feature Release for Akka.NET 🚀 Akka.NET 1.3.0 is a major feature release that introduces the significant changes to Akka.NET and its runtime.
👍 .NET Core and .NET Standard 1.6 Support 🚀 This release introduces support for .NET Standard 1.6 for our core libraries and .NET Core 1.1 for the MultiNode Test Runner standalone executable. All packages for Akka.NET are dual-released under both .NET 4.5 and .NET Standard 1.6.
🏗 As a side note: Akka.NET on .NET 4.5 is not wire compatible with Akka.NET on .NET Core; this is due to fundamental changes made to the base types in the CLR on .NET Core. It's a common problem facing many different serializers and networking libraries in .NET at the moment. You can use a X-plat serializer we've developed here: https://github.com/akkadotnet/akka.net/pull/2947 - please comment on that thread if you're considering building hybrid .NET and .NET Core clusters.
🚀 Akka.Persistence Released to Market ⚡️ Akka.Persistence has graduated from beta status to stable modules and its interfaces are now considered to be stable. We'll begin updating all of the Akka.Persistence plugins to stable and to add .NET Standard / .NET 4.5 support to each of them as well following this patch.
📚 DocFx-based Documentation Site 📚 Documentation is now generated using DocFx and compiled from within the Akka.NET project rather than a separate documentation repository.
API Changes This release does not maintain wire format compatibility with the previous release (v1.2.3) inside Akka.Remote; primarily this is due to having to upgrade from Google Protobuf2 to Protobuf3 in order to add .NET Standard support, but we've also taken the liberty of making other serialization improvements while we're at it. So be advised that during an upgrade from 1.2.* to 1.3.* there will be periods of network disruption between nodes using different versions of the service.
🐎 Akka.Remote Performance Improvements Akka.Remote's throughput has been significantly increased.

v1.2.0 Changes
April 11, 2017🔋 Feature Release for Akka.NET 🚀 Akka.NET 1.2 is a major feature release that introduces the following major changes:
Akka.Remote now uses DotNetty for its transport layer ⬆️ The biggest change for 1.2 is the removal of Helios 2.0 as the default transport and the introduction of DotNetty. The new DotNetty transport is fully backwards compatible with the Helios 1.4 and 2.* transports, so you should be able to upgrade from any Akka.NET 1.* application to 1.2 without any downtime. All of the
helios.tcpHOCON is also supported by the DotNetty transport, so none of that needs to updated for the DotNetty transport to work out of the box.👍 In addition, the DotNetty transport supports TLS, which can be enabled via the following HOCON:
akka { loglevel = DEBUG actor { provider = Akka.Remote.RemoteActorRefProvider,Akka.Remote } remote { dot-netty.tcp { port = 0 hostname = 127.0.0.1 enable-ssl = true log-transport = true ssl { suppress-validation = true certificate { # valid ssl certificate must be installed on both hosts path = "<valid certificate path>" password = "<certificate password>" # flags is optional: defaults to "default-flag-set" key storage flag # other available storage flags: # exportable | machine-key-set | persist-key-set | user-key-set | user-protected flags = [ "default-flag-set" ] } } } } }🔒 You can read more about Akka.Remote's TLS support here.
👀 See the complete DotNetty transport HOCON here.
Akka.Streams and Akka.Cluster.Tools RTMed Akka.Streams and Akka.Cluster.Tools have graduated from beta status to stable modules and their interfaces are now considered to be stable.
CoordinatedShutdown ⏱ One of the major improvements in Akka.NET 1.2 is the addition of the new
CoordinatedShutdownplugin, which is designed to make it easier for nodes that are running Akka.Cluster to automatically exit a cluster gracefully wheneverActorSystem.Terminateis called or when the process the node is running in attempts to exit.CoordinatedShutdownis fully extensible and can be used to schedule custom shutdown operations as part ofActorSystemtermination.📄 You can read more about how to use
CoordinatedShutdownhere.➕ Additional Changes 📚 In addition to the above changes, there have been a large number of performance improvements, bug fixes, and documentation improvements made to Akka.NET in 1.2. Read the full list of changes in Akka.NET 1.2 here.

v1.1.3 Changes
January 22, 2017🚀 Maintenance release for Akka.NET v1.1
🛠 Akka.NET v1.1.3 features some new libraries and an enormous number of bug fixes.
Akka.DistributedData Beta 🔀 First, we've introduced an alpha of a new module intended for use with Akka.Cluster: Akka.DistributedData. The goal of this library is to make it possible to concurrently read and write replicated copies of the same entity across different nodes in the cluster using conflict-free replicated data types, often referred to as "CRDTs." These replicas can eventually be merged together in a fully consistent manner and are excellent choices for applications that require a high level of availability and partition tolerance.
🚧 The library is still a bit of a work in progress at the moment, but you are free to use it via the following command:
PS> Install-Package Akka.DistributedData -pre🗄 Akka.Serialization.Wire Deprecated; Replaced with Akka.Serialization.Hyperion 👀 Wire recently changed its license to GPLv3, which is a poor fit for a technology like Akka.NET. Therefore, our default serializer beginning in Akka.NET 1.5 will be Hyperion instead. You can see how to set it up here: http://getakka.net/docs/Serialization#how-to-setup-hyperion-as-default-serializer

v1.1.2 Changes
September 21, 2016🚀 Maintenance release for Akka.NET v1.1
Akka.NET 1.1.2 introduces some exciting developments for Akka.NET users.
🔧 Mono Support and Improved IPV4/6 Configuration 🚀 First, Akka.NET 1.1.2 is the first release of Akka.NET to be production-certified for Mono. We've made some changes to Akka.Remote, in particular, to design it to work within some of the confines of Mono 4.4.2. For instance, we now support the following HOCON configuration value for the default Helios TCP transport:
helios.tcp { # Omitted for brevity transport-protocol = tcp port = 2552 hostname = "" public-hostname = "" dns-use-ipv6 = false enforce-ip-family = false }🏁
helios.tcp.enforce-ip-familyis a new setting added to thehelios.tcptransport designed to allow Akka.Remote to function in environments that don't support IPV6. This includes Mono 4.4.2, Windows Azure WebApps, and possibly others. When this setting is turned on anddns-use-ipv6 = false, all sockets will be forced to use IPV4 only instead of dual mode. If this setting is turned on anddns-use-ipv6 = true, all sockets opened by the Helios transport will be forced to use IPV6 instead of dual-mode.🚀 Currently, as of Mono 4.4.2, this setting is turned on by default. Mono 4.6, when it's released, will allow dual-mode to work consistently again in the future.
✅ We run the entire Akka.NET test suite on Mono and all modules pass.
Akka.Cluster Downing Providers 🔧 We've added a new feature to Akka.Cluster known as a "downing provider" - this is a pluggable strategy that you can configure via HOCON to specify how nodes in your Akka.NET cluster may automatically mark unreachable nodes as down.
0️⃣ Out of the box Akka.Cluster only provides the default "auto-down" strategy that's been included as part of Akka.Cluster in the past. However, you can now subclass the
Akka.Cluster.IDowningProviderinterface to implement your own strategies, which you can then load through HOCON: -
v1.1.1 Changes
July 15, 2016🚀 Maintenance release for Akka.NET v1.1
⬆️ Akka.NET 1.1.1 addresses a number of bugs and issues reported by end users who made the upgrade from Akka.NET 1.0.* to Akka.NET 1.1.
DNS improvements ⬆️ The biggest set of fixes included in Akka.NET 1.1.1 deal with how the Helios transport treats IPV6 addresses and performs DNS resolution. In Akka.NET 1.0.* Helios only supported IPV4 addresses and would use that as the default for DNS. In Akka.NET 1.1 we upgraded to using Helios 2.1, which supports both IPV6 and IPV4, but changed the default DNS resolution strategy to use IPV6. This caused some breakages for users who were using the
public-hostnamesetting inside Helios in combination with ahostnamevalue that used an IPV4 address.0️⃣ This is now fixed - Akka.NET 1.1.1 uses Helios 2.1.2 which defaults back to an IPV4 DNS resolution strategy for both inbound and outbound connections. We've also fixed the way we encode and format IPV6 addresses into
ActorPathandAddressstring representations (although we still have an issue with parsing IPV6 from HOCON.)If you need to use IPV6 for DNS resolution, you can enable it by changing the following setting:
akka.remote.helios.tcp.dns-use-ipv6 = true
