Sourced from pylint's changelog.

What's New in Pylint 2.4.1?

Release date: 2019-09-25

• Exempt type checking definitions defined in both clauses of a type checking guard

  Close #3127

• Exempt type checking definitions inside the type check guard

  In a7f236528bb3758886b97285a56f3f9ce5b13a99 we added basic support
  for emitting used-before-assignment if a variable was only defined
  inside a type checking guard (using TYPE_CHECKING variable from typing)
  Unfortunately that missed the case of using those type checking imports
  inside the guard itself, which triggered spurious used-before-assignment errors.

  Close #3119

• Require astroid >= 2.3 to avoid any compatibility issues.

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
