# dbus-broker - Linux D-Bus Message Broker
## CHANGES WITH 23:
* Expose supplementary groups as `UnixGroupIDs` as defined by the dbus
specification in 0.53.
* Fix an issue where the launcher incorrectly reported success even
though it could not parse the bus configuration.
* Fix an issue where the launcher was unnecessarily verbose about trying
to start masked units. It will now only log once per unit.
* Fix an issue where transient systemd unit names were not correctly
escaped.
* The broker now uses the peer-pid from `SO_PEERCRED` on the controller
socket, rather than relying on `getppid()`. This allows creating the
broker from intermediate processes without having any credentials of
the intermediate leak into the broker.
