At the beginning of the bar Chopin wrote in A (→GEFE,EE,IE) a cautionary  to a. In the main text we also include the cautionary  to f2 added in GE (→FE,EE,IE).

Whole-bar slur in A

Slur over quavers in GE (→FE,EE,IE)

..

Similarly as in bar 185, in the main text we keep the A slur. The version of the editions can be considered an acceptable variant.

[] suggested by the editors

..

The suggested position of the  mark, overlooked in the sources, is justified by an analogy with bar 185 (cf. also bar 266, 268 and 270).

in A

Longer  in GE (→FE,EE,IE)

..

First editions would often extend Chopinesque  hairpins (as part of revision). In the main text we reproduce the mark after A, although in this case the version of the editions can be considered equal – the mark certainly concerns the entire passage (cf. bar 370).
