The 
asterisk, added both in FC (→GE) and FE (→EE), cannot be authentic. The notation of A implies that the pedal depressed on the 3rd beat of b. 68 should be held to the end of the Prelude; moreover, both the sonic effect of such pedalling and no final mark are typical of Chopin and are to be found in the endings of a number of his compositions. The individual sources slightly differ in the placement of this , hence we assume that there are two slightly different versions.
The pedalling in the last bar is an arbitrary revision of EE.
