+	* Clearify that %U may result in either local paths or file: URLs
+	* Deprecate %d, %n, %D and %N. They aren't usable on Gnome and
+	you can do the same with dirname and basename in a script.
+	* Clearify that %f, %u, %F or %U should only be used once.
+	* Clearify that these codes should be ignored if there is no file
+	to open.
+	* Forbid the use of field codes in quoted arguments.
+	* Clearify that %F and %U should only be used as a stand alone argument.
+	* Bumped version to 1.0
