Slurs of different lengths in GC

7 slurs in FE1 (→FE2)

8 slurs in FE3 (→FE4) & EE

3 slurs in GE1

Slurs of different lengths in GE2

..

Same as in the previous bars, the slurring of GC is very careless in these bars. GE1 printed only three slurs, which was completed in GE2, almost literally reproducing GC. The remaining editions contain correct slurs, only FE1 (→FE2) overlooked the slur at the transition between bars 217 and 218.

d1 in GC (→GE), FE3 (→FE4) & EE

No d1 in FE1 (→FE2)

..

No d1 notes in the 3rd and 4th chords in the R.H. is certainly a mistake of the engraver of FE1 (→FE2), corrected by Chopin in FE3 (→FE4) and the base text to EE.

b. 219

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

The  raising c2 to c2 at the end of bar appears only in FESch (written in), FE4 and EE2. The absence of this accidental constitutes an undoubted oversight by Chopin in [A] – cf. e2 and not e2 in an analogous passage in bars 91-92.
