Hotfix 19 (CPVS61019)
CPVS61019 (widely known as Hotfix 19) is the most current patch for PVS 6.1. It contains both server and target binaries and it’s essentially a full reinstall of PVS. Yes, it does require reverse imaging to upgrade your targets but in turn you get a whole lotta fixes from Stream Process to HA failover and Console performance improvements. Highly recommended!
