The cautionary  before the grace note was written by Chopin in GC (→GE) and probably in the base text to EE. In GE2 (→GE3) a  was added also before the top note of the octave, d3. In the main text we include both signs.

Quavers with mordent in EE1

The version of GC (→GE) and FE, identical with the version of analogous bar 51, is most probably earlier (omission of mordent in FE is almost certainly a mistake). Lack of corrections in GC proves that the version of this copy was also in the autograph rewritten by the copyist. The version with quavers only present in EE1 must have been introduced by Chopin instead of the previous one in the manuscript being the base text to this edition. Therefore we give this version as the later one in the main text. This type of breaking a longer rhythmic value is a characteristic for Chopin way of enriching the melodic line at the time of repeating phrases (cf., e.g., Mazurkas in A major, Op. 7 No. 4, bars 25-32, G minor, Op. 24 No. 1, bars 57 and 59C major, Op. 24 No. 2, bars 97-104C minor, Op. 50 No. 3, bars 77-88, A minor, Op. 59 No. 1, bars 3-6 and 27-30, Waltz in E major, Op. 18, bars 37-51).
EE2 (→EE3) introduced an analogous version to bar 51, most probably under the influence of FE.

The top note of the chord on the 2nd beat of the mar in FE is a b. The mistake was corrected in FED. The remaining sources feature the correct text.
