b. 79

composition: Op. 50 No. 2, Mazurka in A♭ major

No arpeggio signs in A1 (→FEEE)

Arpeggio signs in GE

..

Just like in b. 63, in the main text we include the arpeggios added by Chopin in the proofreading of GE1 (→GE2) or still in [A2].

b. 79

composition: Op. 50 No. 2, Mazurka in A♭ major

..

Just like in b. 63, in the main text we add a  before D. In turn, we do not include the  before the d semiquaver present in A1 (→FEEE). In GE there are no cautionary signs in this bar.

b. 81-82

composition: Op. 50 No. 2, Mazurka in A♭ major

Short & long accent in A1, literal reading

2 short accents in FE (→EE)

No accents in GE

..

The accents on the 3rd beat of these bars were most probably removed in the proofreading of FE, which is proven by small characteristic traces left. Since Chopin replaced them with the cresc. indication and , we do not include them in the main text.
The issue of the length of the accents: see b. 60-64.

b. 81-82

composition: Op. 50 No. 2, Mazurka in A♭ major

No markings in A1 (→FEEE)

cresc. in GE

..

Just like in b. 65-66, in the main text we give the cresc. indication in b. 81 and  in b. 82, added by Chopin probably in the proofreading of GE1 instead of the removed accents on the 3rd beat of those bars.

b. 83

composition: Op. 50 No. 2, Mazurka in A♭ major

No repeat in A1 & EE

Repeat in FE & GE

..

The repeat sign of the section that comes to an end here is an addition introduced by Chopin in the last stage of proofreading of FE as well as in GE or – which seems more likely – still in [A2]
