b. 65

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

 in A (→GE)

No hairpins in FE (→EE)

..

The  present in A (→GE) disappeared in FE (→EE). As it seems unlikely that anybody introduced any corrections in that particular place, the hairpins were probably omitted by mistake.

b. 65

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

..

Before the last semiquaver A (→GEFEEE) has a cautionary (?)  before g flat2. We remove that sign, as being unnecessary in that context.

b. 65-66

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

The slur of A

GE (→FEEE)

..

In  A, the slur of the lower voice is drawn precisely to reach f2 ​in bar 66. Despite that fact, in GE (→FEEE)  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.

b. 66-67

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

No accents in A (→GEFE)

Accents in EE

..

We add accents above d flat3 and c3. Those two figures end the line in A and Chopin probably simply forgot to write those two accents here, but wrote accents for the following three analogous figures in a new line. The missing accents were added in EE. Cf. the note about  slurs.

b. 66-67

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

No slurs over the quavers in A (→GEFEEE)

Slurs suggested by the editors

..

We suggest supplementing two-quaver motifs in bars 66-67 with slurs, just like Chopin marked it in A in bar 68. The notation of bars 66-67 in A  contains a number of omissions which, analysed jointly, point to the composer's weakened concentration. In GE (→FEEE) bars 66-68 only have slurs running from grace notes, which surely stems from careless reproduction of the notation of A, and not from the introduced changes.
