Bump Akka.Hosting.TestKit and Akka.TestKit.Xunit2

[dependabot]

Updated Akka.Hosting.TestKit from 1.5.58 to 1.5.60.

Release notes

Sourced from Akka.Hosting.TestKit's releases.

1.5.60

1.5.60 February 10th 2026

New Features

• Add OpenTelemetry trace correlation support for LoggerFactoryLogger - enables proper trace correlation for logs emitted from actor code. Solves the problem that Activity.Current doesn't flow across actor mailbox boundaries because it uses AsyncLocal<T>. When using Akka.NET 1.5.59+, LogEvent.ActivityContext captures trace context at log creation time and flows it through to OpenTelemetry LogRecords via the new AkkaTraceContextProcessor. Register with options.AddAkkaTraceCorrelation() in your OpenTelemetry logging configuration.
• Add WithContext() integration tests for MEL logger - confirmed that Akka.NET 1.5.60's WithContext() logging context enrichment works automatically with LoggerFactoryLogger. Context properties set via the core WithContext() API flow through to Microsoft.Extensions.Logging state dictionaries via TryGetProperties() without any code changes needed.

Bug Fixes

• Fix WithDefaultLogMessageFormatter<T>() rejecting built-in formatters - SemanticLogMessageFormatter and DefaultLogMessageFormatter have private constructors (they use singleton Instance properties), but the validation only accepted public parameterless constructors. These built-in types are now correctly accepted.

Deprecations

• WithDefaultLogMessageFormatter<T>() is now marked [Obsolete] — SemanticLogMessageFormatter is the default as of Akka.NET 1.5.58 and no longer needs to be set explicitly. The method still works for custom ILogMessageFormatter implementations.

Updates

• Bump Akka version from 1.5.59 to 1.5.60

1.5.60-beta1 January 29th 2026

Beta Release

This is a beta release for testing the OpenTelemetry trace correlation feature that was merged after 1.5.59.

New Features

• Add OpenTelemetry trace correlation support for LoggerFactoryLogger - enables proper trace correlation for logs emitted from actor code. Solves the problem that Activity.Current doesn't flow across actor mailbox boundaries because it uses AsyncLocal<T>. When using Akka.NET 1.5.59+, LogEvent.ActivityContext captures trace context at log creation time and flows it through to OpenTelemetry LogRecords via the new AkkaTraceContextProcessor. Register with options.AddAkkaTraceCorrelation() in your OpenTelemetry logging configuration.

1.5.59 January 2026

New Features

• Add OpenTelemetry trace correlation support for LoggerFactoryLogger - enables proper trace correlation for logs emitted from actor code. Solves the problem that Activity.Current doesn't flow across actor mailbox boundaries because it uses AsyncLocal<T>. When using Akka.NET 1.5.59+, LogEvent.ActivityContext captures trace context at log creation time and flows it through to OpenTelemetry LogRecords via the new AkkaTraceContextProcessor. Register with options.AddAkkaTraceCorrelation() in your OpenTelemetry logging configuration.

Bug Fixes

• Fix semantic logging not capturing named placeholders as structured properties - resolved issue #​701 where named placeholders like {Event} in log messages were not captured as searchable structured properties. Made all LoggerConfigBuilder properties optional and refactored message formatting code.
• Fix TestKit startup timeout race condition - resolved race condition in TestKit.InitializeAsync() where CancellationTokenSource.Register() threw exceptions on the timer thread, causing unhandled exceptions that crashed the test host process. Also increased default startup timeout from 10s to 30s for CI environments.

Updates

• Bump Akka version from 1.5.58 to 1.5.59
• Added OpenTelemetry package dependency (1.9.0+) for trace correlation support

1.5.58 January 9th 2026

Updates

• Bump Akka version from 1.5.57 to 1.5.58

1.5.57 December 16th 2025

New Features

• Add semantic logging support for Akka.NET 1.5.56+ - enables Microsoft.Extensions.Logging to receive properly structured state dictionaries instead of pre-formatted strings. When using Akka.NET 1.5.56+, log messages now include structured properties from the semantic logging API along with Akka metadata (ActorPath, Timestamp, Thread, LogSource). Fully backwards compatible with older Akka.NET versions.

Updates

• Bump Akka version from 1.5.55 to 1.5.57

Updates

• Bump Akka version from 1.5.55 to 1.5.57

1.5.55.1 October 27th 2025

Enhancements

• Expose options in journal and snapshot builders - resolved issue #​690 by adding Options property to AkkaPersistenceJournalBuilder and AkkaPersistenceSnapshotBuilder. Extension methods can now access configuration details without requiring options as explicit parameters, eliminating redundant option passing for connectivity health checks and other plugin-specific features

1.5.55 October 26th 2025

New Features

• Support custom health check registrations on Journal and Snapshot Builders - added API to support custom health check registrations for Akka.Persistence plugins, related to issue #​678
• Add support for custom certificate validation callbacks - integrated the new CertificateValidationCallback feature from Akka.NET v1.5.55, allowing users to provide custom certificate validation logic for SSL/TLS connections. Enables advanced scenarios including certificate pinning, subject/issuer matching, custom business validation rules, and advanced mTLS scenarios

Enhancements

• Add customizable tags parameter to health check methods - resolved issue #​679 by adding new overload allowing custom tags for health checks while maintaining backward compatibility
• Made it easier to customize failureState and tags for all health checks - simplified health check configuration API for all health checks

Updated Akka.TestKit.Xunit2 from 1.5.58 to 1.5.60.

Release notes

Sourced from Akka.TestKit.Xunit2's releases.

1.5.60

1.5.60 February 9th, 2026

Akka.NET v1.5.60 is a maintenance release with a bug fix and a new feature for structured logging.

Bug Fixes

• Fix TestActor initialization race in parallel test startup - Fixes a race condition where TestActor could receive messages before its initialization was complete when tests were run in parallel, causing intermittent test failures.

New Features

• Add logging context enrichment and scopes - Fixes issue #​7535. Adds WithContext() and BeginScope() extension methods to ILoggingAdapter for structured logging context enrichment. Context properties are automatically included in log output and forwarded to downstream logging providers like Serilog and NLog. See documentation.

  var log = Logging.GetLogger(Sys, "example");
  
  // Enrich a logger with additional structured context
  var enrichedLog = log
      .WithContext("Tenant", "foo")
      .WithContext("Partition", 12);
  
  enrichedLog.Info("Processing {Offset}", 42);
  // Output: [INFO][...][akka://sys/user/a][Tenant=foo][Partition=12] Processing 42
  
  // Create a temporary logging scope
  using (var scope = log.BeginScope("RequestId", "REQ-123"))
  {
      scope.Log.Info("Handling request {RequestId}", "REQ-123");
  }

1.5.59

1.5.59 January 27th, 2026

Akka.NET v1.5.59 is a maintenance release with critical bug fixes and new features for observability.

Critical Bug Fixes

• Fix MergeSeen to filter Seen against current Members - Fixes issue #​8009. Resolves a cluster gossip serialization failure that could occur with the error "Unknown address in cluster message" when the Seen table contained addresses of members that had already left the cluster.

Bug Fixes

• Fix logger initialization continuation race in LoggingBus - Fixes a race condition during logger initialization that could cause logging failures during actor system startup.
• Fix Inbox.AwaitResult throwing AggregateException instead of TimeoutException - Inbox.AwaitResult now correctly throws TimeoutException when a timeout occurs, rather than wrapping it in an AggregateException.
• Fix DeferAsync async handler nesting bug in CommandAsync - Fixes issue #​7998. Resolves an issue where DeferAsync with an async handler would throw "RunTask calls cannot be nested" when called from CommandAsync.
• Fix AwaitAssertAsync logic causing premature timeout - Fixes AwaitAssertAsync in Akka.TestKit to correctly wait for the full timeout duration before failing assertions.

New Features

• Add ActivityContext capture to LogEvent for trace correlation - Log events now automatically capture the current System.Diagnostics.ActivityContext when created, enabling correlation between Akka.NET logs and distributed traces in observability platforms like OpenTelemetry, Application Insights, and Jaeger.
• Add BroadcastHub startAfterNrOfConsumers parameter - Fixes issue #​8017. Port from Apache Pekko - adds a startAfterNrOfConsumers parameter to BroadcastHub.Sink<T>() that delays broadcasting until the specified number of consumers have subscribed:

  // Wait for 3 consumers before starting to broadcast
  var sink = BroadcastHub.Sink<int>(startAfterNrOfConsumers: 3, bufferSize: 256);

Improvements

• CoordinatedShutdown: clearly log the reason why we're exiting - CoordinatedShutdown now logs the specific reason for shutdown at INFO level, making it easier to diagnose why an actor system terminated.
