After about a month of development (mostly over the weekends), Manjaro OpenRC 16.10.2 ISO has been released. It was originally not intended as a development edition, but become one since I noticed that it failed to boot in EFI mode both in Virtualbox as well as on bare metal,
and was unable to fix it (has been fixed).
Major changes are the inclusion of Linux 4.8 to better support newer hardware like AMD Polaris, and the inclusion of Pulseaudio for better out of the box support for multiple audio devices (more of that in the release announcement).
Minor changes include switching the icon theme to elementary-xfce-icons (shoutout to oberon2007 for adding it to the community packages), and adding hardinfo for graphical system information, and ffmpegthumbnailer for video thumbnails.
