While proofreading FE1, Chopin changed and clarified the articulation indications in the entire meno mosso fragment. The main change concerned including the 2nd half of the penultimate bar under a slur ending each of the four-bar sections, at the same time deleting staccato dots under an extended slur (bars 71-72, 75-76, 79-80, 87-88, 91-92, 95-96). Moreover, Chopin corrected a few other places too, striving for a more consistent staccato articulation indication in analogous situations than in A – see bars 70-71.
Both FE2 and GE1 repeated the version of FE1 without changes, although GE1 is not free from inaccuracies. In turn, EE and later GE added articulation almost to the shape presented in the main text (not including additional revisions, as in the 2nd half of bar 95 in EE and minor errors).
