The gcrotchet, struck in bar 159 and sustained as a minim in bar 160, was added by Chopin in the last proofreading of FE (→EE). This kind of diversification of subsequent appearances of repeating musical ideas belonged to Chopin's favourite composer tricks.
The proofreading also embraced a change of the graphic layout of the text – the 3rd quaver in the R.H. was moved to the upper stave.

composition: Op. 35, Sonata in B♭ minor, Mvt I

In GC and FE (→EE1) there is no flat lowering c2 to c2 in the L.H. The obvious inaccuracy was corrected in GE & EE2.
