The R.H. bottom voice crotchet on the 2nd beat of the bar is written in AI as f1. Chopin changed it to g1 while writing AF – one can see a crossed-out f1 next to the note.
In EE – just like in b. 164 – cautionary naturals were added before b and a.

Without access to [AG], it is impossible to determine whether and which version Chopin considered to be final. The general concordance between AI and GE suggests that this version was created first; however, even if it was the case, it does not mean that an alternative idea – the version of AF – was already the final word, since there are numerous examples, supported by sources, of returns to original versions, which was poignantly described by George Sand. Therefore, having a choice between two equal authentic versions, in the main text we give the text of GE, which is the principal source adopted for the entire op. 50.
