What you need to do
Nothing, unless you own a T8506 or T85L0 smart lock — see below.
Lock controls on two more models
The Lock and Unlock buttons were only offered on the T8531, the one lock model whose command has been pressed on real hardware. The T8506 and T85L0 now get them too, so their owners can tell us whether the command actually moves the bolt.
These two are unverified. Test at the door, with it open and your key on you, and do not rely on the buttons until someone confirms them. The worst realistic outcome is a lock that ignores a command it does not recognise. Report what happens in #1099 — if the bolt does not move, the buttons come off again.
Every other lock model is unchanged: recognised, and represented by nothing until one of its owners can confirm it.
