Akka.NET v1.5.31

1.5.31 November 11th 2024

Akka.NET v1.5.31 is a maintenance release that addresses several bugs and added new features.

• Persistence: Add logging for failed DeleteAsync() that was caused by failed SaveSnapshot()
• Persistence: Fix RecoveryTick timer leak
• Serialization.Hyperion: Fix serializer config bug
• Sharding: Fix potential ArgumentException during shard re-balancing
• Cluster: Fix multiple Member with the same Address crashing ClusterDaemon
• Core: Fix Stash filtering out identical Envelopes
• Streams: Fix ShellRegistered message deadletter log
• Sharding: Make lease release in Shard.PostStop be blocking instead of using detached async task
• Cluster.Tools: Add missing singleton detection feature for easier infrastructure debugging

Upgrade Advisory

There is a slight change in how actor Stash behavior. In previous behavior, Stash will filter out any messages that are identical (see explanation below) when it is prepended with another. It will not do so now, which is the actual intended behavior.

This change will affect Akka.Persistence users or users who use the Stash.Prepend() method in their code. You will need to add a de-duplication code if your code depends on sending identical messages multiple times to a persistence actor while it is recovering.

Messages are considered as identical if they are sent from the same sender actor and have a payload message that Equals() to true against another message. Example payload types would be an object pointing to the same memory address (ReferenceEquals() returns true), value types (enum, primitives, structs), and classes that implements the IEquatable interface.

Akka.NET v1.5.30

1.5.30 October 1st 2024

Akka.NET v1.5.29 introduced an interface change on the IScheduler that unfortunately caused a lot of other plugins to break due to API compatibility issues. v1.5.30 rolls back that change but still fixes the underlying bug in Akka.Persistence's handling and serialziation of timestamps without any interface changes. v1.5.29 will be deprecated from NuGet.

• DData: Remove Hyperion dependency
• Streams: Fix SelectAsync race condition bug
• Core: Add new IWithTimers API to allow sender override
• Persistence: Fix SnapshotMetadata default timestamp value (DateTimeKind.Utc bug)
• Core: Fix AskTimeoutException message formatting bug
