libei 0.2 is now available. libei is a library to send Emulated Input (EI) to a matching Emulated Input Server (EIS) which can receive those events with libeis, also part of this project.
libei uses GitLab releases, for tarballs please see: https://gitlab.freedesktop.org/libinput/libei/-/releases/0.2 This is a development snapshot and neither API nor ABI should be considered stable. Anyone using libei or libeis must keep both in sync, there are no accommodations made for libei/libeis from different versions and the wire protocol may break at any time. Please see the API documentation here: https://libinput.pages.freedesktop.org/libei/ The git shortlog is below: David Edmundson (1): tools/demo-server: create a seat in uinput mode David Redondo (3):
