This is the sixth release of ebusd 3 and the fourteenth (="O", therefor Orange) since ebusd was completely reworked.
The major new features include support for eBUS adapter 3 in enhanced mode allowing arbitration to be done in hardware, a new tool for flashing the adapter 3 PIC, as well as support for Cygwin builds.
See ChangeLog and Wiki for details.
Debian 9 (Stretch) install packages for amd64, i386, armhf (Raspberry Pi), and arm64 (Raspberry Pi 64 bit) are attached and also available in the Debian repository as described here.
For Debian 10/Buster, you can use the stretch image as well.
Variants of each binary with MQTT support have an additional "mqtt0" (for libmosquitto0) or "mqtt1" (for libmosquitto1) suffix in the name. Those without MQTT support don't have such a suffix.
For Arch Linux, simply run makepkg in the contrib/archlinux/ebusd/ directory.
The latest release is also available as Docker image on the hub with tag ebusd:latest.
