		Additionally, this release adds many improvements for documentation, build
		infrastructure, and testing.

		Major enhancements included with the release:

		* Introduced the Unified Kernel; the nano and micro kernel were removed.
		* The legacy API is still supported but deprecated. All legacy tests were moved
		to tests/legacy.
		* Added Unified Kernel documentation.
		* The legacy API is still supported but deprecated.
		* Legacy tests and samples were moved to tests/legacy and samples/legacy.
		* Unified kernel documentation was added and legacy nanokernel/microkernel
		documentation was removed.
		* Added support for several ARM Cortex-M boards
		* Added support for USB mass storage and access to the filesystem.
