Changelog

  • [BREAKING] Changed GetBlockByNumber to accept a BlockRequest (with optional include_proof flag) and returns a response containing the block and an optional block proof (#1864).
  • Network monitor now auto-regenerates accounts after persistent increment failures instead of staying unhealthy indefinitely (#1942).
