[ANNOUNCE] libinput 1.8.901

Wed Sep 27 06:03:45 UTC 2017

The first RC for libinput 1.9 is now available.

The 1.9 development cycle added quite a few new features so expect
libinput's behaviour to have changed, ideally for the better.

The autotools build system is no more, we are now using meson exclusively.
Building and installing libinput is now usually running
   meson builddir && ninja -C builddir install
More detailed build instructions are available here:
https://wayland.freedesktop.org/libinput/doc/latest/building_libinput.html

Touchpads can now use pressure-based palm detection if the hardware supports
it. A new tool "libinput measure touchpad-pressure" is available to measure
the presure values for your touchpad. This should be stored in a hwdb entry.
If your touchpad doesn't have an entry yet please file a bug with the
tool's output attached so we can make this work for everyone.

On touchpads with ABS_MT_TOUCH_MAJOR/MINOR we can now use those for touch
detection (especially if per-touch pressure is not available). The Apple
touchpads already use this but unfortunately the values are basically random
and every touchpad needs a custom hwdb entry. Please use the
"libinput measure touch-size" tool to find out the right thresholds and file
the required bugs.

Touchpads now ignore extra fingers while the pointer-controlling finger
is moving. This avoids accidentally triggering two-finger scrolling when
lightly touching the touchpad or placing a thumb on the touchpad while
moving.

Trackpoints ("pointingsticks", "that red thing between g and h") have had
their pointer acceleration re-done. The new approach basically punts
most of the acceleration curve to the firmware to avoid unexpected
double-acceleration. libinput merely applies a more-or-less linear factor on
top of that curve based on a device-specific range. As the two items
above, the range is hardware specific and needs a per-device entry. The tool
to measure this is "libinput measure trackpoint-range".

Pointer devices now have button debouncing automagically enabled. 
Ghost button release/press events due to worn out or bad-quality switches
are transparently discarded and the device should just work.

The tablet-mode switch on hybrid laptop/tablet devices (e.g. Lenovo Yoga)
now disables the touchpad, trackpoint and internal keyboard to avoid fake
touches when the tablet is placed on a lap or just held with the fingers
on those devices.

Aside from those main features, the usual bunch of fixes, cleanups,
unicorns, etc.
