A new release of libinput, 0.14.0, is now available.

libinput now provides middle button emulation for physical buttons and, for some devices, a configuration interface to enable said emulation. The API is the usual quartett of configuration queries: libinput_device_config_middle_emulation_is_available() libinput_device_config_middle_emulation_set_enabled() libinput_device_config_middle_emulation_get_enabled() libinput_device_config_middle_emulation_get_default_enabled()

A new tool "libinput-list-devices" was added. This tool lists the locally recognised devices and their respective configuration options and configuration defaults. Example output:

Device:         SynPS/2 Synaptics TouchPad
Kernel:         /dev/input/event4
Group:          9
Seat:           seat0, default
Size:           97.33x62.40mm
Capabilities:   pointer
Tap-to-click:   disabled
Left-handed:    disabled
Nat.scrolling:  disabled
Calibration:    n/a
Scroll methods: *two-finger
Click methods:  *button-areas clickfinger

Note that due to the design of libinput, this tool can only show the default configurations, not the current configuration of each device.

The pointer acceleration range has been widened to allow for greater deceleration and greater acceleration. Since we retain the [-1, 1] range, you may see a slight slowdown or speedup. To get the previous behaviour, use the value: current setting * 2.0/3.0.

Five (or more) finger tapping is now handled correctly, though note we only send events for up to three fingers. libinput now supports multi-tap and drag, so e.g. three taps will execute a triple-click.

Palm detection now avoids accidental tapping, see http://wayland.freedesktop.org/libinput/doc/latest/palm_detection.html

And of course the usual bugfixing, including letting libinput handle more devices such as keyboards with scroll wheels or devices that only consist of a wheel.

As usual, the shortlog is below.

Hans de Goede (8): Fix scroll-threshold check for edge-scrolling to use normalized coordinates Add a delta_coords type and use it were applicable Add a normalized_length helper function and use this where applicable Add a normalized_is_zero helper function Change tp_filter_motion to normalized_coords Rename delta_coords to device_float_coords Change vector_get_direction input to a normalized_coords struct filter: Make acceleration range wider
