I've just got round to updating my gizmo plugin to 13.11.05.0205 from an older 64 bit version (i can dig the version out if important). I am getting script error's in the console for all the xp.get and xp.set functions in previously working code. I have managed to figure out that by changing these to dref API functions clears the errors. I haven't changed every reference in my multi file scripts yet as I just want to be sure that xp functions will not function with these newer gizmo versions any longer and that dref is the new kid on the block and should be used in new script. I know dref has been in the API for a while now but when and why did xp cease, or did it? The API only seems to be current for 12.09.16.1422.
