V4.1.0 BP2

Fixed the issue of session information synchronization and the issue that the nodes to which the DELETE and UPDATE statements are routed are taken as coordinators during an upgrade.
Fixed the issue of session information synchronization in the case of error packets.
Fixed the issue where internal SQL statements are not routed based on the specified IP addresses.
Fixed the issue where disconnection occurs when an SQL statement is executed after xa_start hold.
Fixed the issue that the parsing module of ODP may cause memory leaks.
Fixed the issue where ODP is disconnected and does not try to connect to the IP addresses of other OBServer nodes if an invalid IP address 0.0.0.0:0 is specified for the target_db_server+IP address mode when both the mock and target_db_server+IP address routing modes are supported.
Fixed the issue that in IP address-based routing at the global level, if the first IP address belongs to a log replica, ODP does not retry to connect to an available IP address when a core dump occurs.
Fixed the issue that if the specified IP address belongs to ODP in IP address-based routing, the client is hung due to cyclical forwarding by ODP.
Fixed the issue that disconnection occurs when the specified IP address is 127.0.0.1 in IP address-based routing.
Fixed the issue where connection establishment fails if only last_insert_id is modified.
Fixed the issue where performance jitter occurs in business SQL statements when CPU resources are exhausted due to configuration changes.

Fixed the issue where the cluster is disconnected when the PREPARE stmt1 FROM @A statement is executed.
Fixed the issue that the behavior in random routing is not as expected.
Fixed the issue of request routing where only the partitioning key is specified for a subpartitioned table in the SQL request.

The recovery time objective (RTO) is reduced to a value less than 8s.
The OceanBase 2.0 protocol is optimized to reduce the statements for synchronization.
An error packet will be sent to the client if ODP actively disconnects from the client.
