This is the eighth release of ebusd 3 and the sixth (="Q", therefor Quince) since ebusd was completely reworked.
The major new features are more data types, support for verbose output publishing in MQTT and newer MQTT broker versions, as well as added and extended HTTP JSON endpoints.
See ChangeLog and Wiki for details.
Debian 11 (Bullseye), 10 (Buster), and 9 (Stretch) install packages for amd64, 386, armv7 (Raspberry Pi 2/3/4), and arm64 (Raspberry Pi 3/4 64 bit) are attached and will also be made available soon in the Debian repository as described here.
Variants of each binary with MQTT support have an additional "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 multi-architecture Docker image on the hub with tag ebusd:latest.
