 # NXAGENT_SHAPE                    Old shape code
 # NXAGENT_SHAPE2                   New shape code
 # NXAGENT_FIXKEYS                  Force the release of pressed key when losing focus
 # NXAGENT_CLIPBOARD                Enables clipboard cut and paste function between X servers.
-# NXAGENT_RANDR_MODE_PREFIX        Prefix for RandR modes (i.e., nx_<x>x<y>) (default: nx_)

 # NXAGENT_RANDR_XINERAMA_CLIPPING  cut off invisible window parts in xinerama mode (you probably do not want this)
 # NXAGENT_TIMESTAMP                print duration for some routines
+# NXAGENT_ONSTART                  communicate about startup phase to the original nxclient by NoMachine via selections
+# NXAGENT_WAKEUP=<milliseconds>    Specifies a timeout that makes WaitForSomething() return earlier than normal which
+#                                  enables nxagent to close the splash window at the right time and/or improve connection
+#                                  handling for the xdmcp option. This value has no effect because the code uses
+#                                  NX_TRANS_WAKEUP in os/WaitFor.c instead.
+# NXAGENT_ARTSD                    enable special handling of MCOPGLOBALS property used by artsd.
+# NXAGENT_RENDER_CLEANUP           cleanup padding bits/bytes of glyphs to possibly increase compression rate
