In the main text we give the  hairpins on the basis of A. The marks, written by Chopin's hand and coherent with the indications of the analogous phrase in bars 25-26, do not raise any doubts. Moving the  mark under the stave in FE (→GE,EE) could have been a result of graphic difficulties (lack of space), yet this extension cannot be explained in this way. Perhaps Chopin introduced the mark in a proofreading of FE, as he wanted to prepare the beginning of the longer crescendo in bars 29-31 more clearly.

..

FE (→EE,GE1GE2GE3) has an additional  before g1 in the 1st chord. The unnecessary accidental was removed only in GE4 (→GE5). The layout of sharps in FE allows to claim that the  before gwas initially misprinted instead of the  raising b1 to b1. While proofreading this place, Chopin added only the necessary accidental, leaving the erroneous, yet not influencing the text, unchanged.

f1 & f1 in A

Our suggestion based on FE

g1 & f1 in GE & EE4

..

In A the last note in the 1st half of bar 32 is f1, after which three naturals follow: before f2 in the next chord and before f1 at the end of this and next bars. In a proofreading of FE (→GE,EE) Chopin changed fto g1 and deleted the already unnecessary  before f2. In FE (→EE2EE3) the accidental before the last note in bar 32 was also removed, however, the remaining traces suggest that it was a  and not a . The assumption is confirmed by fappearing in this place in GE (and EE4). In the main text we give the undoubtedly final notation of FE.

e1-f1-d1 in A

e1-f1-d1 in FE (→GE1GE1aGE2, →EE2EE3)

e1-f1-d1 in GE3 (→GE4GE5) & EE4

..

Chopin changed the original version (written in A) while proofreading FE (→GE1GE2, →EE2EE3). At the time of proofreading, the unnecessary  before e1 in the 2nd half of the bar was left. This may have incited the reviser of GE3 (→GE4GE5) to change e1 to e1 in the chord at the beginning of the bar (this totally arbitrary version was also repeated in EE4).
We add a cautionary  before f1 on the 2nd semiquaver.
