While Libinput 1.0 was planned to happen around versions 0.13~0.14 of this input handling project for X.Org and Wayland (and Mir coming up too), we're now up to version 0.21, but it looks like 1.0 is finally coming up soon.

Peter mentioned while announcing Libinput 0.21, "This should've been the 1.0RC1 but we had way too many changes after 0.20 to be comfortable claiming we're stable now. So here's another 0.x release, hopefully the last one."

Libinput 0.21 has some additions to the API, libinput switched internally to using micro-seconds for all time-stamps, thumb detection has been better tuned, and there's also a number of device-specific hardware handling updates.

The libinput 0.21 release announcement with details on all of the changes can be found over on the Wayland-devel list.
