This is the third ("C") version of the completely reworked ebusd (since October 2014).
Some nice features were added, see ChangeLog and Wiki for details.
Debian install packages for amd64, i386, and armhf (Raspberry Pi), as well as binaries for freetz (FritzBox) are attached.
For Arch Linux, simply run makepkg in the contrib/archlinux/ebusd/ directory.
