============================
Release date: 2021-11-25

  was not analyzed properly inside typing guards.

• Fixed a false-positive regression for used-before-assignment for
  typed variables in the body of class methods that reference the same class

  Closes #​5342

• Specified that the ignore-paths option considers "" to represent a
  windows directory delimiter instead of a regular expression escape
  character.

• Fixed a crash with the ignore-paths option when invoking the option
  via the command line.

  Closes #​5437

• Fixed handling of Sphinx-style parameter docstrings with asterisks. These
  should be escaped with by prepending a "".

  Closes #​5406

• Add endLine and endColumn keys to output of JSONReporter.

  Closes #​5380

  are on the line following the parameter name. These were generating
  false positives for missing-param-doc.

  Closes #​5452

  or not in checks
