This occurred in a mixed version ClusterSet; where the primary Cluster is on version 8.3.0; or higher; and the replicas were on versions lower than 8.3.0. The check for group_replication_view_change_uuid was incorrectly performed on the primary Cluster instead of the target Replica Cluster.

It was not possible to remove the instance with remove_instance(); either.$$$$$$add_instance() did not properly handle clone-related errors and did not stop Group Replication if errors were detected.$$$$$$As of this release; add_instance() handles clone-related errors; reverts the state of the target instance and stops Group Replication on that instance. (Bug #36657628)$$$$$$Running AdminAPI operations against MySQL 5.7 instances resulted in an error; due to an attempt to run a query on a non-existent Performance Schema table.$$$$$$As of this release; error handling is included to account for such issues. (Bug #36652642)$$$$$$It was possible to define duplicate instance definitions in the replicationSources list of the Cluster.add_replica_instance() operation.

The operation fails with an informative error. (Bug #36614218)$$$$$$AdminAPI commands which add or rejoin instances to Clusters using Clone did not check the existing members for compatibility. If no compatible members were available; Group Replication fell back to incremental recovery which can fail if Clone was the only supported provisioning method. An unexpected and unhelpful error was returned.$$$$$$As of this release; the following commands have been updated to check compatibility and provide appropriate feedback:$$$$$$ReplicaSet.add_instance()$$$$$$ReplicaSet.rejoin_instance()$$$$$$Cluster.add_replica_instance()$$$$$$Cluster.rejoin_instance()$$$$$$ClusterSet.create_replica_cluster()$$$$$$For a donor to be considered compatible for a recipient:$$$$$$They must be running on the same operating system.$$$$$$They must be running on the same platform.$$$$$$The versions must be compatible:$$$$$$Both must be version 8.0.17; or higher.$$$$$$If both are version 8.0.37; or higher; only their major and minor versions need match.

AdminAPI Bugs Fixed$$$Rebooting a replica cluster from complete outage could result in the cluster rejoining the ClusterSet; but not the instance members of the replica cluster. This happened only if the primary cluster was under heavy load or the replica cluster was missing transactions from the ClusterSet. (Bug #35444244)$$$$$$If the X Protocol port was changed for a cluster member and that member restarted; the AdminAPI did not update the metadata with the new port number; leading to connection errors and so on.$$$$$$As of this release; cluster.status() checks for port changes and cluster.rescan() updates the metadata with the new port number. (Bug #35410360)$$$$$$During a failover of a ClusterSet replication channel; the ClusterSet.status() value clusterSetReplicationStatus reported ERROR and globalStatus returned OK_NOT_REPLICATING. Errors and warnings relating to misconfigured or stopped channels were also returned. These statuses and errors were misleading as the channel was attempting to connect to another source or replica.$$$$$$As of this release; clusterSetReplicationStatus returns CONNECTING; and globalStatus returns OK while a channel connection attempt is ongoing.
