+
+Version 1.6 adds resource leasing and non desktop output management.
+
+ • A “Lease” is a collection of crtcs and outputs which are made
+   available to a client for direct access via kernel KMS and DRM
+   APIs. This is done by passing a suitable file descriptor back to
+   the client which has access to those resources. While leased, those
+   resources aren't used by the X server.
+
+ • A “non-desktop” output is a device which should not normally be
+   considered as part of the desktop environment. Head-mounted
+   displays and the Apple "Touch Bar" are examples of such
+   devices. A desktop environment should be able to discover which
+   outputs are connected to such devices and, by default, not present
+   normal desktop applications on them. This is done by having
+   RRGetOutputInfo report such devices as Disconnected while reporting
+   all other information about the device correctly.
