Chopin hesitated about the pitch of the last quaver. It is already the crossings-out in A that prove that the decision was changed twice – Chopin started with g2, changed it to d2, to return to g2. GE features a g2, however, in the proofreading of FE (→EE), Chopin changed it again to d2. It is the latest version that we give in the main text; yet both versions may be considered to be equal. It is interesting that there are no traces of similar hesitations to be found in an analogous situation, as far as the sound is concerned, 4 bars earlier.
