### [`v1.5.25`](https://togithub.com/akkadotnet/akka.net/blob/HEAD/RELEASE_NOTES.md#1525-June-14th-2024-)
[Compare Source](https://togithub.com/akkadotnet/akka.net/compare/1.5.24...1.5.25)
Akka.NET v1.5.25 includes a critical bug fix for logging and some other minor fixes.
**Logging Errors Introduced in v1.5.21**
Versions \[v1.5.21,v1.5.24] are all affected by [Akka.Logging: v1.5.21 appears to have truncated log source, timestamps, etc from all log messages](https://togithub.com/akkadotnet/akka.net/issues/7255) - this was a bug introduced when we added [the log-filtering feature we shipped in Akka.NET v1.5.21](https://getakka.net/articles/utilities/logging.html#filtering-log-messages).
This issue has been resolved in v1.5.25 and we've [added regression tests to ensure that the log format gets version-checked just like our APIs going forward](https://togithub.com/akkadotnet/akka.net/pull/7256).
Other fixes:
- [Akka.Router: sending a message to a remote actor via `IScheduledTellMsg` results in serialization error](https://togithub.com/akkadotnet/akka.net/issues/7247)
- [Akka.Discovery: Make Akka.Discovery less coupled with Akka.Management](https://togithub.com/akkadotnet/akka.net/issues/7242)

Akka.NET v1.5.22 is a patch release for Akka.NET with a few bug fixes and logging improvement.
- [Streams: Bump Reactive.Streams to 1.0.4](https://togithub.com/akkadotnet/akka.net/pull/7213)
- [Remote: Bump DotNetty.Handlers to 0.7.6](https://togithub.com/akkadotnet/akka.net/pull/7198)
- [Core: Resolve CVE-2018-8292 for Akka.Streams and Akka.Remote](https://togithub.com/akkadotnet/akka.net/issues/7191)
- [Core: Expose `BusLogging` `EventStream` as public API](https://togithub.com/akkadotnet/akka.net/pull/7210)
- [Remote: Add cross-platform support to the exception serializer](https://togithub.com/akkadotnet/akka.net/pull/7222)
**On Resolving CVE-2018-8292**
In order to resolve this CVE, we had to update `DotNetty.Handlers` to the latest version and unfortunately, this comes with about 10% network throughput performance hit. We are looking into possible replacement for `DotNetty` to improve this performance lost in the future (see [`#7225`](https://togithub.com/akkadotnet/akka.net/issues/7225) for updates).

Akka.NET v1.5.15 is a significant release for Akka.NET with some major feature additions and changes.
- [Introducing `Akka.Analyzers` - Roslyn Analysis for Akka.NET](https://getakka.net/articles/debugging/akka-analyzers.html)
- [Akka.Cluster.Sharding: perf optimize message extraction, automate `StartEntity` and `ShardEnvelope` handling](https://togithub.com/akkadotnet/akka.net/pull/6863)

- [Akka.Serialization: `INoSerializationVerificationNeeded` does not handle `IWrappedMessage` correctly](https://togithub.com/akkadotnet/akka.net/pull/7010)
**Akka.Analyzers**
The core Akka NuGet package now references [Akka.Analyzers](https://togithub.com/akkadotnet/akka.analyzers), a new set of Roslyn Code Analysis and Code Fix Providers that we distribute via NuGet. You can [see the full set of supported Akka.Analyzers rules here](https://getakka.net/articles/debugging/akka-analyzers.html).
**Akka.Cluster.Sharding Changes**
In [#6863](https://togithub.com/akkadotnet/akka.net/pull/6863) we made some major changes to the Akka.Cluster.Sharding API aimed at helping improve Cluster.Sharding's performance *and* ease of use. However, these changes *may require some effort on the part of the end user* in order to take full advantage:
- [`ExtractEntityId`](https://getakka.net/api/Akka.Cluster.Sharding.ExtractEntityId.html) and [`ExtractShardId`](https://getakka.net/api/Akka.Cluster.Sharding.ExtractShardId.html) have been deprecated as they *fundamentally can't be extended and can't benefit from the performance improvements introduced into Akka.NET v1.5.15*. It is **imperative** that you migrate to using the [`HashCodeMessageExtractor`](https://getakka.net/api/Akka.Cluster.Sharding.HashCodeMessageExtractor.html) instead.
- You no longer need to handle [`ShardRegion.StartEntity`](https://getakka.net/api/Akka.Cluster.Sharding.ShardRegion.StartEntity.html) or [`ShardingEnvelope`](https://getakka.net/api/Akka.Cluster.Sharding.ShardingEnvelope.html) inside your `IMessageExtractor` implementations, and in fact [`AK2001`](https://getakka.net/articles/debugging/rules/AK2001.html) (part of Akka.Analyzers) will automatically detect this and remove those handlers for you. Akka.NET automatically handles these two message types internally now.
**ClusterClient Serialization Changes**
In [#7032](https://togithub.com/akkadotnet/akka.net/pull/7032) we solved a long-standing serialization problem with the [`ClusterClient`](https://getakka.net/api/Akka.Cluster.Tools.Client.ClusterClient.html) where `Send`, `SendToAll`, and `Publish` were not handled by the correct internal serializer. This has been fixed by default in Akka.NET v1.5.15, but this can potentially cause wire compatibility problems during upgrades - therefore we have introduced a configuration setting to toggle this:
```hocon
```

### [`v1.5.9`](https://togithub.com/akkadotnet/akka.net/blob/HEAD/RELEASE_NOTES.md#159-July-18th-2023-)
[Compare Source](https://togithub.com/akkadotnet/akka.net/compare/1.5.8...1.5.9)
Akka.NET v1.5.9 is a maintenance release that introduces some performance improvements and internal code cleanup/modernization.
**Changes:**
- [Remoting: Make transport adapter component public](https://togithub.com/akkadotnet/akka.net/pull/6838)
**Improvements:**
- [Memory optimization, use `Array.Empty` instead of creating empty arrays](https://togithub.com/akkadotnet/akka.net/pull/6801)
- [Remoting: Log all wrapped message layers during errors](https://togithub.com/akkadotnet/akka.net/pull/6818)
- [Port #6805 and #6807, Improve Stream and Pattern.Backoff instance creation time performance](https://togithub.com/akkadotnet/akka.net/pull/6821)
- [DData: Harden LWWDictionary serialization null check](https://togithub.com/akkadotnet/akka.net/pull/6837)
**Code modernization:**
- [Use C# 9.0 target-typed new()](https://togithub.com/akkadotnet/akka.net/pull/6798)
- [Use C# 8.0 null-coalescing operator](https://togithub.com/akkadotnet/akka.net/pull/6814)
**Update dependency versions:**
- [Bump Google.Protobuf to 3.23.4](https://togithub.com/akkadotnet/akka.net/pull/6826)
- [Bump Akka.MultiNode.TestAdapter to 1.5.8](https://togithub.com/akkadotnet/akka.net/pull/6802)
- [Bump Microsoft.Data.SQLite to 7.0.9](https://togithub.com/akkadotnet/akka.net/pull/6835)
- [Bump Microsoft.Extensions.ObjectPool to 7.0.8](https://togithub.com/akkadotnet/akka.net/pull/6813)
- [Bump Xunit to 2.5.0](https://togithub.com/akkadotnet/akka.net/pull/6825)
**Akka.TestKit.Xunit Changes**
Due to breaking API change in Xunit 2.5.0, updating to Akka.NET 1.5.9 might break your unit tests. Some of the breaking change that we've noticed are:
- `AkkaEqualException` constructor has been changed due to changes in Xunit API. If you're using this class, please use the `AkkaEqualException.ForMismatchedValues()` static method instead of using the constructor.
- Testing for exception types by calling async code inside a sync delegate will not unwrap the `AggregateException` thrown. Either use async all the way or manually unwrap the exception.
- Xunit `Asset.Equal()` does not automatically check for collection item equality anymore, that means doing `Assert.Equal()` between two dictionary or list would not work anymore.
- Some Xunit classes have been changed from public to private. If you're using these classes, you will need to refactor your code.
- **FsCheck.Xunit:** Xunit Roslyn analyzer has become a bit too overzealous and insists that all unit test method can only return either void or Task and will raise a compilation error if you tried to return anything else. If you're using `FsCheck.Xunit`, you will need to use a pragma to disable this check: `#pragma warning disable xUnit1028`.

### [`v1.5.7`](https://togithub.com/akkadotnet/akka.net/blob/HEAD/RELEASE_NOTES.md#157-May-17th-2023-)
[Compare Source](https://togithub.com/akkadotnet/akka.net/compare/1.5.6...1.5.7)
Akka.NET v1.5.7 is a significant release that introduces a [major new reliable message delivery feature to Akka.NET and Akka.Cluster.Sharding](https://getakka.net/articles/actors/reliable-delivery.html): `Akka.Delivery`.
**`Akka.Delivery`**
Akka.Delivery is a reliable delivery system that leverages built-in actors, serialization, and persistence to help guarantee that all messages sent from one producer to one consumer will be delivered, in-order, even across process restarts / actor restarts / network outages.
Akka.Delivery's functionality is divded across four libraries:
- Akka - defines the base definitions for all messages, the `ProducerController` type, and the `ConsumerController` type;
- Akka.Cluster - contains the serialization definitions for Akka.Delivery;
- Akka.Persistence - contains the `EventSourcedProducerQueue` implementation, an optional feature that can be used to make the `ProducerController`'s outbound delivery queue persisted to the Akka.Persistence Journal and SnapshotStore; and
- Akka.Cluster.Sharding - contains the definitions for the `ShardingProducerController` and `ShardingConsumerController`.
We've documented how these features work in the following two detailed articles official website:
- "[Reliable Message Delivery with Akka.Delivery](https://getakka.net/articles/actors/reliable-delivery.html)"
- "[Reliable Delivery over Akka.Cluster.Sharding](https://getakka.net/articles/clustering/cluster-sharding-delivery.html)"

**SQL Transaction Isolation Level Setting**
In 1.5.3, we're introducing fine-grained control over transaction isolation level inside the `Akka.Persistence.Sql.Common` common library. This setting will be propagated to the rest of the SQL persistence plugin ecosystem and the `Akka.Hosting` package in their next release version.
Four new HOCON settings are introduced:
- `akka.persistence.journal.{plugin-name}.read-isolation-level`
- `akka.persistence.journal.{plugin-name}.write-isolation-level`
- `akka.persistence.snapshot-store.{plugin-name}.read-isolation-level`
- `akka.persistence.snapshot-store.{plugin-name}.write-isolation-level`
you can go to the [official Microsoft documentation](https://learn.microsoft.com/en-us/dotnet/api/system.data.isolationlevel?#fields) to read more about these isolation level settings.

```csharp
public interface IActorTelemetryEvent : INoSerializationVerificationNeeded, INotInfluenceReceiveTimeout
{
///
/// The actor who emitted this event.
///

```
These events will be consumed from popular Akka.NET observability and management tools such as [Phobos](https://phobos.petabridge.com/) and [Petabridge.Cmd](https://cmd.petabridge.com/) to help provide users with more accurate insights into actor workloads over time, but you can also consume these events yourself by subscribing to them via the `EventStream`:
```csharp
// subscribe to all actor telemetry events
Context.System.EventStream.Subscribe(Self, typeof(IActorTelemetryEvent));
```
**By default actor telemetry is disabled** - to enable it you'll need to turn it on via the following HOCON setting:
```hocon
akka.actor.telemetry.enabled = on
```
The performance impact of enabling telemetry is negligible, as you can [see via our benchmarks](https://togithub.com/akkadotnet/akka.net/pull/6294#issuecomment-1340251897).
**Fixes and Updates**

##### 1.4.41 August 31 2022
Akka.NET v1.4.41 is a minor release that contains some minor bug fix and throughput performance improvement for Akka.Remote
- [Akka: Fix AddLogger in LoggingBus](https://togithub.com/akkadotnet/akka.net/issues/6028)
Akka loggers are now loaded asynchronously by default. The `ActorSystem` will wait at most `akka.logger-startup-timeout` period long (5 seconds by default) for all loggers to report that they are ready before continuing the start-up process.
A warning will be logged on each loggers that did not report within this grace period. These loggers will still be awaited upon inside a detached Task until either it is ready or the `ActorSystem` is shut down.
These late loggers will not capture all log events until they are ready. If your logs are missing portion of the start-up events, check that the logger were loaded within this grace period.
- [Akka: Log Exception cause inside Directive.Resume SupervisorStrategy warning log](https://togithub.com/akkadotnet/akka.net/issues/6070)
- [DData: Add "verbose-debug-logging" setting to suppress debug message spam](https://togithub.com/akkadotnet/akka.net/issues/6080)
- [Akka: Regenerate protobuf codes](https://togithub.com/akkadotnet/akka.net/issues/6087)
All protobuf codes were re-generated, causing a significant improvement in message deserialization, increasing `Akka.Remote` throughput.

1.4.46->1.5.25Release Notes
akkadotnet/akka.net (Akka.TestKit)
### [`v1.5.25`](https://togithub.com/akkadotnet/akka.net/blob/HEAD/RELEASE_NOTES.md#1525-June-14th-2024-) [Compare Source](https://togithub.com/akkadotnet/akka.net/compare/1.5.24...1.5.25) Akka.NET v1.5.25 includes a critical bug fix for logging and some other minor fixes. **Logging Errors Introduced in v1.5.21** Versions \[v1.5.21,v1.5.24] are all affected by [Akka.Logging: v1.5.21 appears to have truncated log source, timestamps, etc from all log messages](https://togithub.com/akkadotnet/akka.net/issues/7255) - this was a bug introduced when we added [the log-filtering feature we shipped in Akka.NET v1.5.21](https://getakka.net/articles/utilities/logging.html#filtering-log-messages). This issue has been resolved in v1.5.25 and we've [added regression tests to ensure that the log format gets version-checked just like our APIs going forward](https://togithub.com/akkadotnet/akka.net/pull/7256). Other fixes: - [Akka.Router: sending a message to a remote actor via `IScheduledTellMsg` results in serialization error](https://togithub.com/akkadotnet/akka.net/issues/7247) - [Akka.Discovery: Make Akka.Discovery less coupled with Akka.Management](https://togithub.com/akkadotnet/akka.net/issues/7242) You can [see the full set of changes for Akka.NET v1.5.25 here](https://togithub.com/akkadotnet/akka.net/milestones/1.5.25). | COMMITS | LOC+ | LOC- | AUTHOR | | --- | --- | --- | --- | | 6 | 347 | 44 | Aaron Stannard | | 2 | 1197 | 1015 | Gregorius Soedharmo | ### [`v1.5.24`](https://togithub.com/akkadotnet/akka.net/blob/HEAD/RELEASE_NOTES.md#1524-June-7th-2024-) [Compare Source](https://togithub.com/akkadotnet/akka.net/compare/1.5.23...1.5.24) Akka.NET v1.5.24 is a patch release for Akka.NET that addresses CVE-2018-8292 and also adds a quality of life improvement to IActorRef serialization. - [Fix invalid serializer was being used when serialize-message is set to true](https://togithub.com/akkadotnet/akka.net/pull/7236) - [Add Serialization.DeserializeActorRef() QoL method](https://togithub.com/akkadotnet/akka.net/pull/7237) - Resolve CVE-2018-8292 in [this PR](https://togithub.com/akkadotnet/akka.net/pull/7235) and [this PR](https://togithub.com/akkadotnet/akka.net/pull/7238) | COMMITS | LOC+ | LOC- | AUTHOR | |---------|------|------|---------------------| | 3 | 35 | 22 | Gregorius Soedharmo | | 1 | 26 | 51 | Mike Perrin | | 1 | 15 | 2 | Aaron Stannard | You can [see the full set of changes for Akka.NET v1.5.24 here](https://togithub.com/akkadotnet/akka.net/milestones/1.5.24). ### [`v1.5.23`](https://togithub.com/akkadotnet/akka.net/blob/HEAD/RELEASE_NOTES.md#1523-June-4th-2024-) [Compare Source](https://togithub.com/akkadotnet/akka.net/compare/1.5.22...1.5.23) - [Fix missing `HandOverDone` handler in ClusterSingletonManager](https://togithub.com/akkadotnet/akka.net/pull/7230) - [Add push mode to `ShardedDaemonProcess`](https://togithub.com/akkadotnet/akka.net/pull/7229) | COMMITS | LOC+ | LOC- | AUTHOR | |---------|------|------|---------------------| | 2 | 299 | 44 | Aaron Stannard | | 1 | 47 | 49 | Gregorius Soedharmo | | 1 | 1 | 1 | Hassan Abu Bakar | You can [see the full set of changes for Akka.NET v1.5.23 here](https://togithub.com/akkadotnet/akka.net/milestones/1.5.23). ### [`v1.5.22`](https://togithub.com/akkadotnet/akka.net/blob/HEAD/RELEASE_NOTES.md#1522-June-4th-2024-) [Compare Source](https://togithub.com/akkadotnet/akka.net/compare/1.5.21...1.5.22) Akka.NET v1.5.22 is a patch release for Akka.NET with a few bug fixes and logging improvement. - [Streams: Bump Reactive.Streams to 1.0.4](https://togithub.com/akkadotnet/akka.net/pull/7213) - [Remote: Bump DotNetty.Handlers to 0.7.6](https://togithub.com/akkadotnet/akka.net/pull/7198) - [Core: Resolve CVE-2018-8292 for Akka.Streams and Akka.Remote](https://togithub.com/akkadotnet/akka.net/issues/7191) - [Core: Expose `BusLogging` `EventStream` as public API](https://togithub.com/akkadotnet/akka.net/pull/7210) - [Remote: Add cross-platform support to the exception serializer](https://togithub.com/akkadotnet/akka.net/pull/7222) **On Resolving CVE-2018-8292** In order to resolve this CVE, we had to update `DotNetty.Handlers` to the latest version and unfortunately, this comes with about 10% network throughput performance hit.
