+1.6. Introduction to version 1.6 of the extension
+
+Version 1.6 adds resource leasing.
+
+ • 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.
+
+Version 1.6 adds EDID-based output 'grabbing'.
+
+ • An 'Output Grab' matches a set of EDID Manufacturer ID and product
+   codes. For outputs with matching EDID values, the connected status
+   of the output is only visible to the grabbing client. Other clients
+   will see the output as disconnected. Attempts to configure the
+   grabbed output by other clients will fail.

+	follows:
+
+	• Crtcs are reported as having no 'possible-outputs' and all
+	  other values reported as if the crtc were disabled.
+
+	• Outputs are reported as having no crtcs they can be
+	  connected to, no clones they can share a crtc with, will
+	  report a connection status of Disconnected, and will show
+	  the current crtc as Disabled.
+
+	The lease remains in effect until the file descriptor is
+	closed, even if the client holding the lease disconnects from
+	the X server.
