  <summary>Changelog</summary>
  
  
   ### 4.3.0
   ```
   =========================

Deprecations
------------

- `4724 &lt;https://github.com/pytest-dev/pytest/issues/4724&gt;`_: ``pytest.warns()`` now emits a warning when it receives unknown keyword arguments.

  This will be changed into an error in the future.



Features
--------

- `2753 &lt;https://github.com/pytest-dev/pytest/issues/2753&gt;`_: Usage errors from argparse are mapped to pytest&#39;s ``UsageError``.


- `3711 &lt;https://github.com/pytest-dev/pytest/issues/3711&gt;`_: Add the ``--ignore-glob`` parameter to exclude test-modules with Unix shell-style wildcards.
  Add the ``collect_ignore_glob`` for ``conftest.py`` to exclude test-modules with Unix shell-style wildcards.


- `4698 &lt;https://github.com/pytest-dev/pytest/issues/4698&gt;`_: The warning about Python 2.7 and 3.4 not being supported in pytest 5.0 has been removed.

  In the end it was considered to be more
  of a nuisance than actual utility and users of those Python versions shouldn&#39;t have problems as ``pip`` will not
  install pytest 5.0 on those interpreters.


- `4707 &lt;https://github.com/pytest-dev/pytest/issues/4707&gt;`_: With the help of new ``set_log_path()`` method there is a way to set ``log_file`` paths from hooks.



Bug Fixes
---------

- `4651 &lt;https://github.com/pytest-dev/pytest/issues/4651&gt;`_: ``--help`` and ``--version`` are handled with ``UsageError``.


- `4782 &lt;https://github.com/pytest-dev/pytest/issues/4782&gt;`_: Fix ``AssertionError`` with collection of broken symlinks with packages.
   ```
   
  
  
   ### 4.2.1
   ```
   =========================

Bug Fixes
---------

- `2895 &lt;https://github.com/pytest-dev/pytest/issues/2895&gt;`_: The ``pytest_report_collectionfinish`` hook now is also called with ``--collect-only``.


- `3899 &lt;https://github.com/pytest-dev/pytest/issues/3899&gt;`_: Do not raise ``UsageError`` when an imported package has a ``pytest_plugins.py`` child module.


- `4347 &lt;https://github.com/pytest-dev/pytest/issues/4347&gt;`_: Fix output capturing when using pdb++ with recursive debugging.


- `4592 &lt;https://github.com/pytest-dev/pytest/issues/4592&gt;`_: Fix handling of ``collect_ignore`` via parent ``conftest.py``.


- `4700 &lt;https://github.com/pytest-dev/pytest/issues/4700&gt;`_: Fix regression where ``setUpClass`` would always be called in subclasses even if all tests
  were skipped by a ``unittest.skip()`` decorator applied in the subclass.


- `4739 &lt;https://github.com/pytest-dev/pytest/issues/4739&gt;`_: Fix ``parametrize(... ids=&lt;function&gt;)`` when the function returns non-strings.


- `4745 &lt;https://github.com/pytest-dev/pytest/issues/4745&gt;`_: Fix/improve collection of args when passing in ``__init__.py`` and a test file.


- `4770 &lt;https://github.com/pytest-dev/pytest/issues/4770&gt;`_: ``more_itertools`` is now constrained to &lt;6.0.0 when required for Python 2.7 compatibility.


- `526 &lt;https://github.com/pytest-dev/pytest/issues/526&gt;`_: Fix &quot;ValueError: Plugin already registered&quot; exceptions when running in build directories that symlink to actual source.



Improved Documentation
----------------------

- `3899 &lt;https://github.com/pytest-dev/pytest/issues/3899&gt;`_: Add note to ``plugins.rst`` that ``pytest_plugins`` should not be used as a name for a user module containing plugins.


- `4324 &lt;https://github.com/pytest-dev/pytest/issues/4324&gt;`_: Document how to use ``raises`` and ``does_not_raise`` to write parametrized tests with conditional raises.


- `4709 &lt;https://github.com/pytest-dev/pytest/issues/4709&gt;`_: Document how to customize test failure messages when using
  ``pytest.warns``.



Trivial/Internal Changes
------------------------

- `4741 &lt;https://github.com/pytest-dev/pytest/issues/4741&gt;`_: Some verbosity related attributes of the TerminalReporter plugin are now
  read only properties.
