 in A

GE (→FE→EE)
..

The  in A is written on the lower staff, so it clearly relates to A flat1 of the L.H. In GE (→FE→EE) the marking is placed higher, between the staves, so it is not clear what it applies to. In the main text we preserve the notation of A, as in GE there are no signs that the marking was moved.

Long accents in A

Short accents in GE (→FE→EE)
..

In GE (→FE→EE), both accents over the crotchets in the right hand were interpreted as short ones, despite their considerable size in A (cf. short accents in bars 62-64).

b. 61

composition: Op. 27 No 2, Nocturne in D♭ major

..

In GE, the four last notes of the R.H.: e flat1-f1-e flat1-d flat1, are placed - against their rhythmic values - precisely above the four last semiquavers of the L.H. (e flat-c1-g flat-A flat). FE and EE have those notes placed correctly.

The slur of A

GE (→FE→EE)
..

In  A, the slur of the lower voice is drawn precisely to reach f2 ​in bar 66. Despite that fact, in GE (→FE→EE)  the slur ends on the last semiquaver of bar 65. It is very unlikely that the correction was actually made by Chopin, as there are no traces of introducing any changes in GE.

Crotchet stems in A (→GE2) in bar 68

 No stems in GE1

Extended duration of d flat notes begins from bar 67 in FE (→EE)
..

In A, Chopin notated the extended values of d flat notes only in bar 68 (which was overlooked in GE1, and supplemented in #Wn2). In the proofing of FE (→EE) the composer added crotchet stems and dots to five notes, in the manner analogous to  bars 63-65.
