A new release of libinput, 0.20.0, is now available. 

The big new addition in this release is support for touchpad gestures,
implemented by Hans de Goede. Two types of gestures are supported: swipe and
pinch. Swipe is triggered by a movement of 3+ fingers in the same
direction, pinch is triggered by two fingers moving towards or away from
each other and/or a rotation around a logical center.
Both gestures, once triggered, can move around the touchpad, making it
possible to use them for fine-grained motion.

The gestures follow a begin/update/end cycle, similar to touch events. The
new events are 
Gesture support is a new capability on the device:
Please refer to the API documentation for more information.

Note that gesture handling in libinput does merely interpret and pass on the
gestures, it is up to the caller to act on them.

Edge scrolling is now possible on clickpads too and thus available on all
touchpads. Thumb detection was added, it is now possible to rest the thumb
on a clickpad while moving a pointer without interference.

libinput now requires touchpads to have a resolution. If the kernel device
does not set it and none of the hwdb rules do either, libinput assigns a
default resolution to the device. This may have an effect on your touchpad,
please file a bug if you notice anything untoward. On the positive side it
removes the magic numbers sprinkled through the code.
