++
++ CAN bus
++ -------
++
++ - Introduced categorized logging to the module which can be enabled
++ by the "qt.canbus" and "qt.canbus.plugins.<pluginname>" filters.
++
++ - Added description, serial number and channel to QCanBusDeviceInfo, as
++ far as supported by the various plugins.
++
++ - [QTBUG-63294] QCanBusFrame::isValid() now checks for invalid CAN FD
++ payload lengths. E.g. 24 is a valid CAN FD payload length, but 28
++ is not. Frames with invalid data field size may therefore be discarded
++ by QCanBusDevice::writeFrame() as it is impossible to transmit them on
++ a real CAN bus.
++
++ - All CAN bus plugins that don't support CAN FD now also discard CAN FD
++ frames with payload length <= 8.
++
++ - Added a J2534 Pass-Thru CAN bus plugin.
++
++ - [QTBUG-67030] Fixed a receive problem in the VectorCAN plugin. When
++ multiple channels were open, only the first one could receive frames.
++
++ MOD bus
++ ------
++
++ - [QTBUG-66648] Ensure that QModbusDevice::close() handles being already
++ unconnected. Before, an unconnected device could hang in closing state
++ forever.
