In A the bottom note of the 4th quaver was corrected by Chopin from g to a (similarly in bars 2, 5, 6 and 22). In the 1st bar, the result of this correction is not that obvious, at the first sight, and the version of EE proves that probably the copyist preparing the base text for this edition misinterpreted Chopin's intention.

Chopin doubled the bass progression in the bottom octave in the proofreading of FE (cf. bar 19, in which Chopin also reinforced the bass note, adding an octave). The change, which is certainly to be considered to be final, was also introduced – in the form of added quavers under notes – in EE2 (→EE3).
The missing staccato dot (as well as accent) in FE is most probably a result of an imprecisely performed proofreading.
