The first RC for libinput 1.10 is now available.

The 1.9 development cycle was a fairly quiet one with few big features and
most of the actual bugfixes have found their way into the 1.9.4 release

The biggest feature is the dropping of the touchpad hysteresis. Previously,
we employed a hysteresis to avoid pointer wobbles. A side-effect of that
hysteresis was that small pointer motion wasn't as reactive as it should be.
A previous attempt in 2016 to drop it failed (too many devices still needed
it) so this time round we have a different approach: we analyse the event
sequence from the touchpad and if we find it doesn't wobble, we disable the
hysteresis for good. In most cases, this happens fast enough that you won't
even notice, resulting in a more reactive pointer.

A new button debouncing code fixes the occasional issues seen with stuck
buttons. That code has already made it into 1.9.3 though, so you're likely
already running it anyway.

Touchpad tapping now handles palm detection where applicable, resting a palm
on a touchpad while tapping should not confuse libinput anymore. Previously,
palm touches were treated like any other touch, causing unexpected 2 and
3-finger clicks.

Some of the newer Wacom tablets (and older, worn-out ones) can have a
leftover pressure on tip up. This caused libinput to miss out on the
proximity event, leading to a constantly in-proximity tool. A new threshold
for proximity out fixes this.

As usual, the git shortlog is below.
