b. 152-165

Slur in FE0

Long slur in FE1

Four slurs in FEG (→GE1)

Four slurs in EE

Five slurs in GE2 (→GE3)

..

The slurring in bars 159-164 is clearly incomplete in FE0, which may be a result of Chopin's inaccuracies in [A], errors of the engraver or both. Chopin then changed and completed the slurs in FEG, the base text to EE and proofreading of FE1, yet in all of them differently. In total, it gives three different authentic slurring versions. In the main text we give the version written by Chopin's hand in FEG (→GE1), as in the case of FE and EE, there is a slight possibility that Chopin proofreading was overlaid with certain mistakes, manners or revisions of the engravers.
It is not entirely clear what the motivation of the reviser of GE2 (→GE3) was at the time of breaking the slur between bars 159 and 160.

b. 173

composition: Op. 42, Waltz in A♭ major

d1-e1 in FE (→FEGGE1)

d1-e1-g1 in EE & GE2 (→GE3)

..

The d1-e1 second featured in FE and GE1 is the original version, which is proven by the comparison with the remaining four analogous places in bars 49, 81, 113 and 269. In three out of five places Chopin added to it a gnote in FEG (→GE). In EE the completed version with the d1-e1-g1 chord is in all five places, which also proves Chopin's proofreading. Therefore, the fact of leaving the original version of the discussed bar in FE and GE1 must be considered as Chopin's oversight.
