- Update to version 1.7.99.1:
- libevdev support:
The evdev backend on Linux now uses libevdev. We recommend
to use libevdev 1.1-rc1 or later as the synaptics driver is
very likely to trigger SYN_DROPPED and we've fixed a bunch
of issues in libevdev 1.1.
- Support for T440, T540, X240, Helix, Yoga:
The bulk of the changes is to support this set of Lenovo
touchpads. These touchpads don't have separate physical
buttons for the trackstick and need to be emulated as
software-button by the driver.
- TouchpadOff behaviour change:
Synaptics has a property "Synaptics Off" to disable events.
Previously, this disabled any event from the touchpad.
Now, physical button clicks are allowed even when the
touchpad is disabled.
- mtdev was dropped:
There are no touchpad drivers in the kernel tree that
use protocol A, so using mtdev is just a computationally
expensiv and memory-wasting noop.
- As per upstream change, swap pkgconfig(mtdev) BuildRequires for
pkgconfig(evdev) >= 1.0.99.1
- Rebase n_xf86-input-synaptics-wait.diff for this release

- Update to version 1.7.4:
One fix: closing the fd again if the device cannot be enabled
properly, and two reverts: scrollbuttons and circular pad
support are making a comeback. Apparently there are still a
few laptops out there that require either feature.
