SIINEOS
-------

* General:
	- Base system updated to Debian GNU/Linux 10.3 release

	- Increased USB gadget announced power consumption to 400 mA
	- Strip more unused files from the filesystem image to improve size and performance
	- Allow QML apps to listen on TCP ports < 1024 (e.g. for Modbus TCP server)
	- Reduce power consumption and thermal emissions of hardware by dynamically scaling CPU frequency based on workload
* Kernel:
