Notable bug fixes
- Process advancing: the partition cleanup job no longer deletes advance events that are accepted while cleanup is running. Event insertion and cleanup now coordinate through database row locks, on both PostgreSQL and Oracle, so a process advance can no longer be lost to a concurrent cleanup.
- Process advancing: advancing workers no longer pause for cooldown while work is still queued, and event completion is retried after a database deadlock instead of leaving an already-processed event marked as in progress.
- Process designer: deleting an action no longer fails with a server error when one of its business rules calls a reusable function.
