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.
