Moving the moment of introducing e1 after eis another change of this type – cf. bar 66 and 70. However, in this place, Chopin eventually opted for an earlier introduction of the altered note.

b. 78

composition: Op. 64 No 2, Waltz in C♯ minor

Slur in AI

No sign in A (→FEGE,EE)

According to us, the little slur of AI, although not included in the version prepared for print, may be considered a specification of the final notation of the Waltz.

b. 79-80

composition: Op. 64 No 2, Waltz in C♯ minor

..

There is no  before the top most note of the chord in bar 79 in A (→GE1op), necessary before gdue to the notation in the four-flat key signature. The sign was added in the remaining GE. In bar 80, Chopin did not write a  before the lowest note of the last chord in A. The sign, although only cautionary in this context, is undoubtedly justified in this place and it was added in GE.

b. 80-81

composition: Op. 64 No 2, Waltz in C♯ minor

..

The slurring of AI, in the same way as in bars 65-72, is related to the regular four- and eight-bar structure of the phrases – one slur ends on the last quaver in bar 80, whereas the next one begins from the minim in bar 81. The slurring of A corresponds to the moved, more freely shaped phrases. In fact, the first slur does not go beyond bar 80, yet its shape clearly suggests leading it to a1 in bar 81. This is how it was interpreted in FE and in the remaining editions; these are also the slurs we give in the main text. Since both authentic slurrings are clearly linked to the rhythmic structure of the phrases, corresponding variants are included in the next note on rhythm.

In As, in which the second half of this section (bars 81-96) is written only in the form of alternative versions of the first one (bars 65-80), the bar is to be interpreted as identical to bar 65 (except for the bass note at the beginning). However, it cannot be excluded that it is an inaccuracy of notation and that Chopin provided there for a version with an agrace note, like it is in AI.
The slurring is discussed in the adjacent note.
