libinput 1.3 is now available. 

The main addition over 1.2 is support for so-called tablet pads, i.e.
the actual tablet part of a graphics tablet. This concludes the graphics
tablet work in libinput, we are now feature-complete.
Since the rc2 we only had a documentation change, so below is the
announcement for 1.3rc1.

Tablet pads feature three input sources - buttons, rings and strips. Rings
and strips provide data in degrees and normalized, respectively, with a
similar "source" system as we already offer for pointer axis sources.
Buttons are just that, a sequential list of buttons starting at index 0 -
this is a notable departure from the linux/input.h event codes we use in the
pointer and the tablet tool interface.

The second notable addition are middle buttons for touchpads with a software
button area. Previously, a middle button could be triggered by pressing with
a finger in the left and right button area simultanously. Unfortunately, too
many touchpads are unable to reliably detect both fingers. The middle button
area is always available when software buttons are enabled and encompasses
the center 15-20mm on the touchpad.

We already had middle button scrolling available on trackpoints, with this
release middle button emulation now works as well. Thus, scrolling is
available on trackpoints that don't have a physical middle button.

Finally, touchscreens that have a fuzz value set on the kernel device are
now defuzzed in libinput, thus stopping pointer wobbles previously seen when
holding the finger still. Note that libinput does not *set* the fuzz value,
it merely uses it. Employ a udev rule or hwdb entry to set this on your
device if needed.

The git shortlog is from 1.2.x to make it look more interesting.
