The earlier pedal release, marked in A (→GE) and still earlier – in EE1, are written in the sources transferring the original version of the bass motif in bars 25-26 (with single notes). Relation of pedalling with the sound of the bass progression seems to be quite likely, hence in the main text we give 
at the end of the bar, in accordance with FE, in which Chopin introduced an improved version of the bass.
