MySQL 8.0.24来了。但，略失望。。。

Group Replication’s allowlist of hosts from which an incoming Group Communication System connection can be accepted, can now be updated while Group Replication is still running. You can therefore add new members to a group controlled by an allowlist without needing to stop and restart Group Replication. The allowlist is specified by the group_replication_ip_allowlist system variable on each group member.

Replication: When MySQL Server counted the number of GTIDs in a set, it was possible for the return value to wrap, returning an incorrect result. This could lead to an incorrect decision to use state transfer from the binary log for Group Replication’s distributed recovery, when a remote cloning operation would have been more efficient. The logic has now been corrected. (Bug #32086209)

It is now possible to use START REPLICA SQL_THREAD and STOP REPLICA SQL_THREAD statements for the group_replication_applier channel when Group Replication is stopped. This enables an operator to apply any remaining unapplied transactions on a server that left the group, without having to rejoin the server to the group. (Bug #32027612, Bug #32414767)
