Major changes
Added support for OceanBase Database V4.3.5.0.
Bug fixes
Fixed the issue where, after a binlog server goes down, the disaster recovery mechanism may fail, leading to misjudgment of multi-node failures and repeated attempts to restart, which can cause the Binlog cluster to crash.
Fixed the issue where data in the binlog index file is discontinuous in large transaction scenarios.
Fixed the issue where binlog instance management actions (such as creation, recovery, startup, or deletion) may trigger repeated scheduling on multiple nodes after a single failure.
Fixed the issue of duplicate calculation for the binlog monitoring metric binlog_instance_convert_fetch_storage_rps.
Fixed the issue where releasing connections after concurrent access to the MetaDB may cause the binlog server to crash.
