In the main text we give the 
sign visible in FE (→GE,EE) in bar 77. However, we do not include the 
sign in bar 79, most probably added by revisers of GE and EE3 (→EE4). Leaving the end of a piece without the pedal release mark is quite often in Chopin's pieces and can offer some performance suggestions, cf., e.g., Etudes No. 7-9 or Nocturnes, Op. 27.
