Dear hakkers,

We are pleased to announce a new patch release of Akka 2.5. Some notable improvements and bug fixes in 2.5.13 are:

- Fixed issue that `ByteString.copyToArray` could drop bytes [16303](https://github.com/akka/akka/issues/16303), thanks to [@htmldoug](https://github.com/htmldoug)
- Fixed issue that `ReceiveTimeout` not triggered in some case when combined with `NotInfluenceReceiveTimeout` messages [#24770](https://github.com/akka/akka/issues/24770), thanks to [@newca12](https://github.com/newca12)
- Fixed issue with `RestartFlow.onFailuresWithBackoff` [#24726](https://github.com/akka/akka/issues/24726)
- Fixed issue with `SourceRef` and `SinkRef` timeout [#24934](https://github.com/akka/akka/issues/24934), thanks to [@svozniuk](https://github.com/svozniuk)
- Improved cleanup of Artery associations that could result in long term memory leaks, [#24973](https://github.com/akka/akka/issues/24973)
- Configurable SSLEngineProvider in remoting [#23732](https://github.com/akka/akka/issues/23732)
- More convenient Java API for `recover`, `recoverWith` and `recoverWithRetries` in Streams [#24888](https://github.com/akka/akka/issues/24888), thanks to [@satansk](https://github.com/satansk)

A total of 96 issues were closed since 2.5.12. The complete list can be found on the [2.5.13 milestone](https://github.com/akka/akka/milestone/129?closed=1) on github.

## API changes in Akka Typed

Some of the [improvements](https://github.com/akka/akka/issues?utf8=%E2%9C%93&q=is%3Aissue+label%3At%3Atyped+milestone%3A2.5.13+is%3Aclosed+) to Akka Typed resulted in three small API changes since 2.5.12 and it should be a straight forward find-replace migration.

1. `initialState` was renamed to `emptyState` in `PersistentBehavior`, [#24917](https://github.com/akka/akka/issues/24917)

2. `ActorMaterializer` moved [#24868](https://github.com/akka/akka/issues/24868)

Scala:

```auto
import akka.stream.typed.ActorMaterializer -> akka.stream.typed.scaladsl.ActorMaterializer

```

Java:

```auto
import akka.stream.typed.ActorMaterializer -> akka.stream.typed.javadsl.ActorMaterializerFactory

```

1. `akka-testkit-typed` renamed to `akka-actor-testkit-typed` [#25084](https://github.com/akka/akka/issues/25084)

Artifact:

```auto
akka-testkit-typed -> akka-actor-testkit-typed

```

Package:

```auto
akka.testkit.typed -> akka.actor.testkit.typed

```

Config:

```auto
akka.typed -> akka.actor.typed
akka.testkit.typed -> akka.actor.testkit.typed

```
