4.3.0

Many enhancements are added to this version for easier configuration and \ 
administration. A new cluster membership mechanism is introduced to dynamically \ 
adjust the Watchdog cluster size. This allows the leader Watchdog node to retain \ 
the quorum/VIP even when some of watchdog nodes get Shutdown or disconnected. \ 
New PostgreSQL 14 SQL parser is imported. The Snapshot Isolation Mode is now \ 
ready for production. New sample configuration for the mode is provided in the \ 
configuration example section.
