Hello,
obarun repository is now up to date. Some change come with this update :
Mesa, mesa-vdpau, opencl-mesa, libva-mesa-driver, vulkan-intel, vulkan-radeon aren't maintained anymore. You need to install those package from Archlinux extra repo. To do this for example for mesa package, simply :
$ sudo pacman -S extra/mesa
do the same for all your needed packages.
Skalibs, execline, s6, s6-linux-utils, s6-networking, s6-portable-utils, s6-rc have a new release. You can find those package on testing repo. It's a good idea to test it as soon as possible. simply enable the obarun-testing repo on your pacman.conf.
