In A (→FE) there is no  before the last note of the roulade, raising d4 to d4. That inaccuracy, typical of Chopin, was corrected in FC (→GE) and EE. However, in FC the added  covered the small notehead, as a result of which GE1 interpreted the note as a small protuberance on a ledger line below that note, which resulted in c4. The mistake, patent in this harmonic context, was corrected in GE2 (→GE3).

The absence of a  must be Chopin's oversight (this bar is written in A at the end of the line, which promotes inaccuracies). In the main text we suggest adding the mark analogously to the 1st half of the bar, since the authenticity of the  mark added in FC (→GE) and FE (→EE) at the end of the bar is questionable.

In A this bar is added on a stave below; the place in which it should be inserted is also marked. The addition of the bar could have been related to the changes of the rhythmic values of the final cadence, which was initially a bar longer.
In FC the bar was marked in an abridged manner as repetition of the previous one.
