libinput 1.29-rc1 (1.28.901) is now available. This release brings a large number of internal changes, so we're going through the release-candidate process to iron out potential issues before the proper release. Expect the final 1.29 release in the next few weeks, depending on how much testing feedback we get.
The vast majority of patches this cycle were internal rework but we do have
a few notable user-visible changes.
For scroll wheel mice we have a new heuristic for detecting inadvertent scroll
wheel movement. This should improve scroll wheel responsiveness for most
devices.
Some Asus "ASUE ..." touchpads had quite jerky motion and cursor jumps. This
was caused by (kernel-triggered) key repeat events that weren't fully ignored
by libinput. This issue is fixed now.
Virtual devices (e.g. those created by uinput) are now detected in libinput and
some internal features are disabled (currently the scroll wheel heuristics and
tablet smoothing). If a device is software-controlled anyway we can punt these
heuristics to said software.
A new set of configuration options are available with
libinput_tablet_tool_config_eraser_button_set_button and
libinput_tablet_tool_config_eraser_button_set_mode
and the corresponding get/get_default calls. An eraser button on a tablet tool
is one hardcoded (in the firmware, as per MS specs) to emulate the pen going
out of proximity and immediately re-entering proximity as eraser - as if the
pen was inverted to use the eraser end.
With the new configuration options users can now opt to have those eraser
buttons send an actual button event instead.
The biggest internal change is the implementation of an internal plugin
pipeline. Kernel evdev event frames are now passed through a pipeline of
plugins that can modify and/or emulate additional events and frames in the
process. This allowed us to move a few internal features to plugins, making
them more self-contained and easier to maintain. There is no public plugin
interface yet, we're hoping to ship one in the next version once we know the
internal pipeline works fine.
This rework came on top of a few code modernisation features such as finally
using __attribute__((cleanup)), improvements to the test suite and use of
clang-format for consistency in the code.
The mtdev dependency is now optional but should generally be left enabled to
support kernel multitouch protocol A devices.
And of course we have the usual assortment of device-specific quirks and fixes.
