In the main text we give the cresc. indication in b. 65 and the 
mark in b. 66, added by Chopin probably in the proofreading of GE1. The composer replaced with them the accents on the 3rd beat of those bars, present in A1 (→FE→EE). The change shows a version of dynamics with longer breath, closer related to the ascending melodic sequence, as superior to a regular mazurka accentation.
