Release highlights:

  • The performance and stability of the message store has improved dramatically. Query durations, even for long-term stores, have improved by more than a factor of 10.
  • Support for Waku Peer Exchange - a discovery method for resource-restricted nodes.
  • Messages can now be marked as "ephemeral" to prevent them from being stored.
  • Zerokit is now the default implementation for spam-protected relay with RLN.

The full list of changes is below.

  • Continued refactoring of several protocol implementations to improve maintainability and readability.
  • Cleaned up nwaku imports and dependencies.
  • Refactored and organised nwaku unit tests.
