The visible evolution of the accompanying part generally consisted in an each time earlier introduction of the diminished seventh chord – in As on the last beat of bar 93, in AI – a crotchet earlier, in the version intended for print – already in bar 92. In both earlier autographs, the bars are an exact repetition of bars 76-77 (also in the melodic line); in turn, in the final version, Chopin clearly differentiated between the mood of the phrase's climax – for the first time, the diminished chord naturally introduces a D
major cadence; for the second time, the harmonic course is dramatically suspended on this chord, whereas the descending phrase in the R.H. carefully avoids any associations with the D major key.
In FE, there is no 
raising g1 to g1 in bar 93, which became necessary after a 5th flat in the key signature was added – cf. bars 64-96. The inadvertence was corrected in EE. The sign was added – unnecessarily – also in GE2no2.
