[ANNOUNCE] libinput 1.18.901

Wed Sep 1 04:50:50 UTC 2021

libinput 1.18rc1 is now available.

This release brings two new features and the correspoding API additions: hold
gestures and high-resolution wheel scrolling (which changes the scroll APIs).

Hold gestures are a new type of gestures that are triggered by holding one or
more fingers on a touchpad without significant movement. They add to the
existing pinch and swipe gestures and allow for the implementation of
hold-to-click. Where callers implement kinetic scrolling, hold gestures can be
used to stop scrolling - since the gesture is triggered on a finger(s) down
after a scroll motion, that event can be used to stop scrolling.
Many thanks to José Expósito for the new gestures.

High-resolution wheel scrolling has been long in the making and the solution
ends up replacing the existing pointer axis API. Three new events are
available: LIBINPUT_EVENT_POINTER_SCROLL_WHEEL,
LIBINPUT_EVENT_POINTER_SCROLL_FINGER, and
LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS. These events **replace** the
existing LIBINPUT_EVENT_POINTER_AXIS events, i.e. if you are processing the
new events simply discard the old events.

The FINGER and CONTINUOUS events are very similar to the previous event, the
WHEEL event supporst a new API: libinput_event_pointer_get_scroll_value_v120().
That function returns the value of a scroll movement in multiples or fractions
of 120. For example, a high-resolution scroll event that triggers 4 events
instead of just 1 per 15 degree rotation will generate 4 events with a value
of 30 each.

Many thanks to José Expósito for taking those patches and pushing them over
the line so they could be merged.

The documentation has been updated for the new APIs,
please see https://wayland.freedesktop.org/libinput/doc/latest/.

The rest of the changes is the usual mix of janitorial patches and
device-specific quirks.
