FE2 added a cautionary  before g1, undoubtedly justified after g1 appearing in this edition at the end of the previous bar. Similarly in EE3, where the cautionary  was added both in the R.H. and in the L.H. before g.

In the majority of the sources, there are inaccuracies concerning the notation of accidentals, not having an impact on the interpretation of the text. In AI, A (→CDP) and FE, there are no naturals before the 3rd note in the L.H. (a) and the 4th note in the R.H. (e1), while in EE1, there is no  before the 3rd note in the R.H. (c2). GE and EE2 (→EE3) have the correct text. In some of the sources, there are additional cautionary accidentals – naturals before A in the middle of the bar and a1 in the last group in AI and before c3 in GE3 (→#GE4).

The flat raising d2 to d2 was added only in EE2 (→EE3) and GE2 (→GE3). There is no doubt that Chopin committed a mistake here, in face of the  before d1 in the L.H.
