HUD has published the 2.0 version of the UPCS-V protocol. This new version revises the previous 1.5 version with some substantive changes as to what constitutes a deficiency as well as grammar edits, formatting edits, and language clarifications. In addition to the protocol itself, HUD has also published a “UPCS-V Protocol Change Tracker” which documents all the changes from the 1.5 version of the protocol to the 2.0 version of the protocol.
