Pyflakes has been updated to >= 2.2.0, < 2.3.0 (See also #982)
pycodestyle has been updated to >= 2.6.0a1, < 2.7.0 (See also #983)

Add --extend-exclude option to add to --exclude without overwriting (See also #1211, #1091)
Move argument parsing from optparse to argparse (See also #939
Group plugin options in --help (See also #1219, #294)
Remove parsing of verbose from configuration files as it was not consistently applied (See also #1245, #245)
Remove parsing of output_file from configuration files as it was not consistently applied (See also #1246)
Resolve configuration files relative to cwd instead of common prefix of passed filenames. You may need to change flake8 subproject to cd subproject && flake8 . (See also #952)
Officially support python3.8 (See also #963)
--disable-noqa now also disables # flake8: noqa (See also #1296, #318)
Ensure that a missing file produces a E902 error (See also #1262, #328)
# noqa comments now apply to all of the lines in an explicit \ continuation or in a line continued by a multi-line string (See also #1266, #621)

Fix --exclude=./t.py to only match t.py at the top level (See also #1208, #628)

Only enable multiprocessing when the method is fork fixing issues on macos with python3.8+ (See also #955, #315) (note: this fix also landed in 3.7.9)
noqa is now only handled by flake8 fixing specific-noqa. Plugins requesting this parameter will always receive False (See also #1214, #1104)
Fix duplicate loading of plugins when invoked via python -m flake8 (See also #1297)
Fix early exit when --exit-zero and --diff are provided and the diff is empty (See also #970)
Consistently split lines when \f is present when reading from stdin (See also #976, #202)

python setup.py flake8 (setuptools integration) is now deprecated and will be removed in a future version (See also #935, #1098)
type='string' (optparse) types are deprecated, use type=callable (argparse) instead. Support for type='string' will be removed in a future version (See also #939)
