…he 'levelsOfUndo' limit was reached. The userInfo dictionary associated to the notification contains the to-be-dropped action for the GCUndoManagerActionKey key. Two notifications are, in fact, posted: GCUndoManagerWillDropUndoActionNotification when dropping undo actions, or GCUndoManagerWillDropRedoActionNotification when dropping redo actions. The latter is only posted when setting 'levelsOfUndo' to a number greater than the current count of the redo stack.

Hi Sean,
Thanks for your latest changes. The only difference in my fork now is just revision 50e7189, which posts a notification when actions are about to be dropped because the undo limit has been reached. I'm using it to release some internal data structures in my application when I'm sure they are not going to be needed any more because the possibility of undoing expired. It's helping my housekeeping a good deal, but I don't know if it would be interesting for a generality of users, though.
Thanks!
