+    - Customize handling of floating windows' move/resize/restack requests

+      applications (Steam, rxvt-unicode, anything that tries to restore
+      absolute position of floats).

     - The history file is not extraneously read and written anymore if
       the `historySize` is set to 0.

+      flicker and also fixes disappearing menus in the Steam client and
+      possibly a few other client applications.
