* Resolve E713 and E714 (not in/is tests). * Address UP018 (unnecessary str call). * UP045 requires Python 3.10+. * Address UP007 (X | Y for type annotations). * Address UP035 (import Callable from collections.abc). * Address UP006 (t.Dict -> dict). * Address UP009 (UTF-8 encoding comment). * Address UP034 (extraneous parantheses). * Address SIM910 (dict.get() with None default). * Address F401 (unused import). * Address UP020 (use builtin open). * Address B009 and B010 (getattr/setattr with constant name). * Address SIM300 (Yoda conditions). * UP029 isn't in use anyway. * Address FLY002 (static join). * Address B034 (re.sub positional args). * Address B020 (loop variable overrides input). * Address B017 (assert raise Exception). * Address SIM211 (if expression with false/true). * Address SIM113 (enumerate for loop). * Address UP036 (sys.version_info checks). * Remove unnecessary UP039. * Address SIM201 (not ==). * Address SIM212 (if expr with twisted arms). * Add changelog fragment. * Reformat.
