Akka.NET v1.5.57-beta1 is a beta release containing a significant new feature for structured/semantic logging.

New Features:

• Add native semantic logging support with property extraction - Fixes issue #7932.

Key capabilities include:
  • New LogMessage.PropertyNames and GetProperties() APIs for property extraction
  • SemanticLogMessageFormatter as the new default formatter
  • Performance optimized with 75% allocation reduction compared to the previous implementation
  • Zero new dependencies and fully backward compatible
  • EventFilter support for semantic templates in unit tests
