A new release of libinput, 0.21.0, is now available. 

This should've been the 1.0RC1 but we had way too many changes after 0.20 to
be comfortable claiming we're stable now. So here's another 0.x release,
hopefully the last one.

A new addition to the API is the configuration option to toggle
disable-while-typing. It's still enabled by default, but can now be disabled
for the use-cases where it is problematic (games, for example). The API is
the usual quartett of configuration options:

The second addition to the API is the ability to get the time in
microseconds from an event:
libinput switched internally to use µs for all timestamps which will help
those devices that have a sampling frequency of more than 1000Hz. Many
thanks to Jonas Ådahl for implementing this feature.

Thumb detection, added for 0.20 has seen fine-tuning to reduce the number of
misdetection. Likewise, the gesture code has seen a bunch of changes to tune
the reliability of gesture detection, especially on semi-mt touchpads.
Scrolling is now more reactive too, with reduced thresholds before scrolling
kicks in.

We've also merged a bunch of device-specific device handling to work around
quirks and deficiencies in some touchpad hardware.

Note that if your distribution is on kernel 4.1.x, you should add this patch
here to your distribution's package unless kernel dbf3c37086 is in your tree

As usual, the git shortlog is below.
