In the main text we omit the cautionary 
to d
1, present in all sources. Chopin probably inserted it due to d1 in the next bar, yet the change of mode had already been indicated by the change of g1 to g1, hence the notation of both bars should be clear.
Two notes later we also omit the unnecessarily repeated 
to e1.
