 - Fix a bug where `GetBlockPendingUpdates` fails to report pending updates to the finalization
   committee parameters.
+- Run GRPC queries in dedicated threads. This improves node resource management
+  and increases responsiveness of the GRPC server in cases of high number of
+  concurrent queries. To support this a new option `--grpc2-max-threads`
+  (environment variable `CONCORDIUM_NODE_GRPC2_MAX_THREADS`) is
+  added which specifies the number of threads that the node should use for
+  processing gRPC requests. If not set this defaults to the number of (logical)
+  CPUs.
+- The option `--grpc2-max-concurrent-streams` now defaults to `200` from the
+  previous unbounded value. This makes the node defaults safer.
