What's New in Pylint 2.4.0?

Release date: 2019-09-24

• New check: import-outside-toplevel

  This check warns when modules are imported from places other than a
  module toplevel, e.g. inside a function or a class.

• Handle inference ambiguity for invalid-format-index

  Close #2752

• Removed Python 2 specific checks such as relative-import,
  invalid-encoded-data, missing-super-argument.

• Support forward references for function-redefined check.

  Close #2540

• Handle redefinitions in case of type checking imports.

  Close #2834

• Added a new check, consider-using-sys-exit

  This check is emitted when we detect that a quit() or exit() is invoked
  instead of sys.exit(), which is the preferred way of exiting in program.

  Close #2925

• useless-suppression check now ignores cyclic-import suppressions,
  which could lead to false postiives due to incomplete context at the time
  of the check.

  Close #3064

• Added new checks, no-else-break and no-else-continue

  These checks highlight unnecessary else and elif blocks after
  break and continue statements.

  Close #2327

• Don't emit protected-access when a single underscore prefixed attribute
  is used inside a special method

  Close #1802
