3.8.0a1 -- 2020-04-24

You can view the 3.8.0 milestone on GitHub for more details.

New Dependency Information

  • Remove dependency on entrypoints and add dependency on importlib-metadata (only for python<3.8) (See also 1297, 297)
  • 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)

Features

  • 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)

Bugs Fixed

  • Fix --exclude=./t.py to only match t.py at the top level (See also 1208, 628)
  • Fix --show-source when a file is indented with tabs (See also 1218, 719)
  • Fix crash when --max-line-length is given a non-integer (See also 939, 704)
  • Prevent flip-flopping of indent_char causing extra E101 errors (See also 949, pycodestyle#886)
  • 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)

Deprecations

  • 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)
  • %default in plugin option help text is deprecated, use %(default)s instead. Support for %default will be removed in a future version (See also 939)
  • optparse-style action='callback' setting for options is deprecated, use argparse action classes instead. This will be removed in a future version (See also 939)
