Changelog

3.0.5

=====

• Add warning when not passing option=value correctly to -o/--override-ini (2105).
  Also improved the help documentation. Thanks to mbukatov for the report and
  lwm_ for the PR.

• Now --confcutdir and --junit-xml are properly validated if they are directories
  and filenames, respectively (2089_ and 2078). Thanks to lwm for the PR.

• Add hint to error message hinting possible missing __init__.py (478). Thanks DuncanBetts.

• More accurately describe when fixture finalization occurs in documentation (687). Thanks DuncanBetts.

• Provide :ref: targets for recwarn.rst so we can use intersphinx referencing.
  Thanks to dupuy_ for the report and lwm_ for the PR.

• In Python 2, use a simple +- ASCII string in the string representation of pytest.approx (for example "4 +- 4.0e-06")
  because it is brittle to handle that in different contexts and representations internally in pytest
  which can result in bugs such as 2111. In Python 3, the representation still uses ± (for example 4 ± 4.0e-06).
  Thanks kerrick-lyft for the report and nicoddemus_ for the PR.

• Using item.Function, item.Module, etc., is now issuing deprecation warnings, prefer
  pytest.Function, pytest.Module, etc., instead (2034).
  Thanks nmundar for the PR.

• Fix error message using approx with complex numbers (2082).
  Thanks adler-j for the report and nicoddemus_ for the PR.

• Fixed false-positives warnings from assertion rewrite hook for modules imported more than
  once by the pytest_plugins mechanism.
  Thanks nicoddemus_ for the PR.

• Remove an internal cache which could cause hooks from conftest.py files in
  sub-directories to be called in other directories incorrectly (2016).
  Thanks d-b-w for the report and nicoddemus_ for the PR.

• Remove internal code meant to support earlier Python 3 versions that produced the side effect
  of leaving None in sys.modules when expressions were evaluated by pytest (for example passing a condition
  as a string to pytest.mark.skipif)(2103).
  Thanks jaraco for the report and nicoddemus_ for the PR.

• Cope gracefully with a .pyc file with no matching .py file (2038). Thanks
  nedbat.
