• birth & last will message on topic systemctl/[hostname]/status ("online" / "offline", https://github.com/fphammerle/systemctl-mqtt/issues/38)
• command-line option --monitor-system-unit [unit_name] enables reports on topic systemctl/[hostname]/unit/system/[unit_name]/active-state (https://github.com/fphammerle/systemctl-mqtt/issues/56)
• automatic discovery in home assistant:
  • availability status
  • entity button.[hostname]_logind_lock_all_sessions
  • entity button.[hostname]_logind_poweroff
  • entity button.[hostname]_logind_suspend
  • entity sensor.[hostname]_unit_system_[unit_name]_active_state for each command-line parameter --monitor-system-unit [unit_name]
• command-line option --log-level {debug,info,warning,error,critical}
• suggest polkit rule when poweroff & locking fails due to org.freedesktop.DBus.Error.InteractiveAuthorizationRequired (https://github.com/fphammerle/systemctl-mqtt/issues/67)
• declare compatibility with python3.11, python3.12 & python3.13

Changed

• disable retain flag on topic systemctl/[hostname]/preparing-for-shutdown
• migrated from dbus-python to pure-python jeepney (removes indirect dependency on libdbus, glib, PyGObject and pycairo, fixes https://github.com/fphammerle/systemctl-mqtt/issues/39)
• migrate from paho-mqtt to its async wrapper aiomqtt
• automatic discovery in home assistant:
  • replaced component-based (topic: <discovery_prefix>/binary_sensor/<node_id>/preparing-for-shutdown/config) with device-based discovery (<discovery_prefix>/device/<object_id>/config)
  • replaced command-line option --homeassistant-node-id with --homeassistant-discovery-object-id
  • renamed entity binary_sensor.[hostname]_preparing_for_shutdown to binary_sensor.[hostname]_logind_preparing_for_shutdown
  • disabled "retain" flag for discovery messages (to avoid reappearing ghost devices)
• container image / dockerfile:
  • upgraded alpine base image from 3.13.1 to 3.21.0 including upgrade of python from 3.8 to 3.12
  • support build without git history by manually setting build argument SETUPTOOLS_SCM_PRETEND_VERSION
• changed default log level from debug to info

Fixed

• apparmor profile for architectures other than x86_64/amd64 (ImportError: Error loading [...]/_gi.cpython-38-aarch64-linux-gnu.so: Permission denied)
• fatal org.freedesktop.DBus.Error.InteractiveAuthorizationRequired when attempting to lock sessions
• container image / dockerfile:
  • split pipenv install into two stages to speed up image builds
  • chmod files copied from host to no longer require o=rX perms on host
  • added registry to base image specifier for podman build
  • added --force flag to rm invocation to avoid interactive questions while running podman build

Removed

• compatibility with python3.5, python3.6, python3.7 & python3.8

Internal

• pipeline:
  • build container image for armv6 & arm64 (in addition to amd64 & armv7)
  • push container images to ghcr.io
  • create tags & labels for container image via docker/metadata-action

0.5.0 - 2020-11-06

Added

• MQTT message on topic systemctl/hostname/lock-all-sessions instructs all sessions to activate screen locks (functionally equivalent to command loginctl lock-sessions)

• docker image:
  • upgrade paho-mqtt to no longer suppress exceptions occuring in mqtt callbacks ( https://github.com/eclipse/paho.mqtt.python/blob/v1.5.1/ChangeLog.txt#L4 )
  • build stage: revert user after applying chown workaround for inter-stage copy
