This is the fourth release of ebusd 3 and the twelfth (="M", therefor Mango) since ebusd was completely reworked.
Besides some bug fixes, the major new features include more options for MQTT broker connection (publish all instead of changes only, setting the client ID and protocol version, log library events) and using single quotes for TCP client command arguments.
See ChangeLog and Wiki for details.
Debian install packages for amd64 (9/Stretch and 8/Jessie), i386 (8/Jessie), and armhf (Raspberry Pi on 9/Stretch, 8/Jessie, and 7/Wheezy) are attached and are also made available in the Debian repository as described here.
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.
