Replication 15.7.1 includes several changes to improve
usabilty.
Reduce Replication Definitions for Customized Function Strings in Warm Standby and MSA Environments
In a replication system containing only Adaptive Server databases, you do not need to create replication definition for a primary table or stored procedure in a warm standby environment or multisite availability (MSA) environment if the sole purpose of the replication definition is to specify a customized function string for the replicate table or stored procedure.
Simplified Upgrade
Replication Server offers a simplified process for upgrading user databases and RSSDs.
