• remove-duplicate-dict-key and remove-duplicate-set-key were enhanced to refactor dicts and sets in any context (previously they were only applied in assignments).

Fixed

• Comments will now show on the correct line where there are functions with docstrings. Addresses issue #211

• F-strings containing escaped characters will not be refactored into constant strings. Addresses issue #213.

• str-prefix-suffix now triggers in the correct way for applying endswith

• use-assigned-var: Do not apply if the variable is overwritten in a loop

• use-itertools-product will now combine nested products. Fixes issue #214.

• We now assume any and all write to their arguments, since they exhaust iterators. This fixes issue #210
