For consistency with upstream naming, the lirc-utils package was renamed to lirc. The wpc8769l kernel drivers were dropped and can be obtained by installing [lirc-wpc8769l from the AUR].
Note that 0.9.2 is a major release and comes along with several upstream and packaging changes. In particular, the `irexec.service` systemd unit was removed. Please edit and copy the template `/usr/share/lirc/contrib/irexec.service` if you want to keep using that service.
