This is the seventh release of ebusd 3 and the fivteenth (="P", therefor Plum) since ebusd was completely reworked.
The major new features are the multi-architecture Docker image as well as the still new support for eBUS adapter 3 in enhanced mode allowing arbitration to be done in hardware.
See ChangeLog and Wiki for details.
Debian 10 (Buster), 9 (Stretch), and 8 (Jessie) install packages for amd64, i386, armel (Raspberry Pi 1/Zero), armhf (Raspberry Pi 2/3/4), and arm64 (Raspberry Pi 3/4 64 bit) are attached and also available 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.
