Thanks! Usually there's an email when something new gets posted to My Tesla; must have missed it.
The Cruise Control section of this new v6.0 manual still doesn't mention the fact that moving the cruise control level up will continue to accelerate long after you let go of the lever, until you reach a +5 mph increase in speed from where you started. Freaked me out the first time I used it, as I thought it was going to keep accelerating right into the back of the truck ahead of me. There's a 1 mph increment as well, but you have to barely tap the stalk to get that behavior, and it isn't documented. The wording specifically says "move the cruise control lever up (increase) or down (decrease) until your desired speed is reached." To me, that sounds like you should be able to take your hand off the lever once you reach the desired speed to maintain that speed, but unfortunately it doesn't behave that way. Hopefully this will get clarified in a future update.
