The first RC for libinput 1.4 is now available.

The main feature merged in this cycle is mode support for graphics tablets.
On many tablets, buttons, rings and strips can be used in virtualised modes,
reflected by physical LEDs on the touchpad. For example, a ring may send
scroll events when in mode 0 but zoom events in mode 1.
A broader explanation of this feature is available here:
Note that the backend implementation of pad modes is effectively
nonexistent. We are currently working on the kernel patches to clean up the
LED system for Wacom tablets, until this is in place all tablets will simply
feature a single mode and group.

We now support rotation on some relative devices. This is particularly
useful for trackballs that may be permanently placed at a nonzero rotation angle.
See libinput_device_config_rotation_set_angle() in the libinput
documentation for more info.

A feature that has found its way into the 1.3.x stable series is the
re-introduction of touchpad hysteresis handling to stop pointer wobbles. Too
many devices do not handle input coordinates reliably enough and playing
whack-a-model with each laptop model was simply not good enough.

The mouse and lens cursor tools on tablets are now accelerated like a normal
1000dpi mouse when used for relative coordinates. Styli's relative
coordinates remain non-accelerated.

Aside from that we had the usual fixes, and, like always, mostly in the
touchpad code.

As usual, the git shortlog is below.
