The g note was added (in pencil) in GC (→GE). Therefore, it is highly likely an addition introduced by Chopin in the last phase of corrections in Stichvorlage manuscripts. The version was adopted in EE3.

Same as in bar 5,  in EE is the original version – in GC one can see correction of  to  performed with Chopin's hand. Here, however, Chopin forgot to introduce a new indication in the base text to FE or resigned from repeating the indication, remembering the entry in bar 5. The second possibility, however, seems to be less likely due to dim. in bars 7-8.

The  sign was added in GC probably by Chopin. GE extended it, so it filled both bars, in this version it was added also in EE2.

FE and EE have no sharps returning f2 and f at the beginning of the 2nd half of the bar. This patent oversight was corrected by Chopin in GC (→GE), when he added the necessary signs.
