 This patch publishes the active fullscreen window on the root window so other
 programs can react to it. It applies to dwm 6.8.
 
-dwm sets `_DWM_FULLSCREEN` to the window id of the fullscreen client when it
-enters fullscreen, and removes the property when it leaves or is unmanaged. A
-compositor, notification daemon or GameMode helper can watch it with:
+dwm sets `_DWM_FULLSCREEN` to the window id of the selected fullscreen client.
+It removes the property when the selected client is not fullscreen. Focus and
+fullscreen changes update the property, so it remains correct across tags,
+monitors, client exits, and multiple fullscreen clients. A compositor,
+notification daemon or GameMode helper can watch it with:
 
 	xprop -root -spy _DWM_FULLSCREEN
 
 No configuration and no spawned commands.
 
-Assumes one fullscreen client at a time. With two, the property tracks the
-most recent one to enter.

 ## Testing
 
-Applies and builds against dwm 6.8. Runtime tested under Xvfb: the property
-is set on enter and cleared on exit and on unmanage.
