   ### 5.1.0
   ```
   =========================

Removals
--------

- `5180 &lt;https://github.com/pytest-dev/pytest/issues/5180&gt;`_: As per our policy, the following features have been deprecated in the 4.X series and are now
  removed:

  * ``Request.getfuncargvalue``: use ``Request.getfixturevalue`` instead.

  * ``pytest.raises`` and ``pytest.warns`` no longer support strings as the second argument.

  * ``message`` parameter of ``pytest.raises``.

  * ``pytest.raises``, ``pytest.warns`` and ``ParameterSet.param`` now use native keyword-only
    syntax. This might change the exception message from previous versions, but they still raise
    ``TypeError`` on unknown keyword arguments as before.

  * ``pytest.config`` global variable.

  * ``tmpdir_factory.ensuretemp`` method.

  * ``pytest_logwarning`` hook.

  * ``RemovedInPytest4Warning`` warning type.

  * ``request`` is now a reserved name for fixtures.


  For more information consult
  `Deprecations and Removals &lt;https://docs.pytest.org/en/latest/deprecations.html&gt;`__ in the docs.


- `5565 &lt;https://github.com/pytest-dev/pytest/issues/5565&gt;`_: Removed unused support code for `unittest2 &lt;https://pypi.org/project/unittest2/&gt;`__.

  The ``unittest2`` backport module is no longer
  necessary since Python 3.3+, and the small amount of code in pytest to support it also doesn&#39;t seem
  to be used: after removed, all tests still pass unchanged.

  Although our policy is to introduce a deprecation period before removing any features or support
  for third party libraries, because this code is apparently not used
  at all (even if ``unittest2`` is used by a test suite executed by pytest), it was decided to
  remove it in this release.

  If you experience a regression because of this, please
  `file an issue &lt;https://github.com/pytest-dev/pytest/issues/new&gt;`__.


- `5615 &lt;https://github.com/pytest-dev/pytest/issues/5615&gt;`_: ``pytest.fail``, ``pytest.xfail`` and ``pytest.skip`` no longer support bytes for the message argument.

  This was supported for Python 2 where it was tempting to use ``&quot;message&quot;``
  instead of ``u&quot;message&quot;``.

  Python 3 code is unlikely to pass ``bytes`` to these functions. If you do,
  please decode it to an ``str`` beforehand.



Features
--------

- `5564 &lt;https://github.com/pytest-dev/pytest/issues/5564&gt;`_: New ``Config.invocation_args`` attribute containing the unchanged arguments passed to ``pytest.main()``.


- `5576 &lt;https://github.com/pytest-dev/pytest/issues/5576&gt;`_: New `NUMBER &lt;https://docs.pytest.org/en/latest/doctest.htmlusing-doctest-options&gt;`__
  option for doctests to ignore irrelevant differences in floating-point numbers.
  Inspired by Sébastien Boisgérault&#39;s `numtest &lt;https://github.com/boisgera/numtest&gt;`__
  extension for doctest.



Improvements
------------

- `5471 &lt;https://github.com/pytest-dev/pytest/issues/5471&gt;`_: JUnit XML now includes a timestamp and hostname in the testsuite tag.


- `5707 &lt;https://github.com/pytest-dev/pytest/issues/5707&gt;`_: Time taken to run the test suite now includes a human-readable representation when it takes over
  60 seconds, for example::

      ===== 2 failed in 102.70s (0:01:42) =====



Bug Fixes
---------

- `4344 &lt;https://github.com/pytest-dev/pytest/issues/4344&gt;`_: Fix RuntimeError/StopIteration when trying to collect package with &quot;__init__.py&quot; only.


- `5115 &lt;https://github.com/pytest-dev/pytest/issues/5115&gt;`_: Warnings issued during ``pytest_configure`` are explicitly not treated as errors, even if configured as such, because it otherwise completely breaks pytest.


- `5477 &lt;https://github.com/pytest-dev/pytest/issues/5477&gt;`_: The XML file produced by ``--junitxml`` now correctly contain a ``&lt;testsuites&gt;`` root element.


- `5523 &lt;https://github.com/pytest-dev/pytest/issues/5523&gt;`_: Fixed using multiple short options together in the command-line (for example ``-vs``) in Python 3.8+.


- `5524 &lt;https://github.com/pytest-dev/pytest/issues/5524&gt;`_: Fix issue where ``tmp_path`` and ``tmpdir`` would not remove directories containing files marked as read-only,
  which could lead to pytest crashing when executed a second time with the ``--basetemp`` option.


- `5537 &lt;https://github.com/pytest-dev/pytest/issues/5537&gt;`_: Replace ``importlib_metadata`` backport with ``importlib.metadata`` from the
  standard library on Python 3.8+.


- `5578 &lt;https://github.com/pytest-dev/pytest/issues/5578&gt;`_: Improve type checking for some exception-raising functions (``pytest.xfail``, ``pytest.skip``, etc)
  so they provide better error messages when users meant to use marks (for example ``pytest.xfail``
  instead of ``pytest.mark.xfail``).


- `5606 &lt;https://github.com/pytest-dev/pytest/issues/5606&gt;`_: Fixed internal error when test functions were patched with objects that cannot be compared
  for truth values against others, like ``numpy`` arrays.


- `5634 &lt;https://github.com/pytest-dev/pytest/issues/5634&gt;`_: ``pytest.exit`` is now correctly handled in ``unittest`` cases.
  This makes ``unittest`` cases handle ``quit`` from pytest&#39;s pdb correctly.


- `5650 &lt;https://github.com/pytest-dev/pytest/issues/5650&gt;`_: Improved output when parsing an ini configuration file fails.


- `5701 &lt;https://github.com/pytest-dev/pytest/issues/5701&gt;`_: Fix collection of ``staticmethod`` objects defined with ``functools.partial``.


- `5734 &lt;https://github.com/pytest-dev/pytest/issues/5734&gt;`_: Skip async generator test functions, and update the warning message to refer to ``async def`` functions.



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

- `5669 &lt;https://github.com/pytest-dev/pytest/issues/5669&gt;`_: Add docstring for ``Testdir.copy_example``.



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

- `5095 &lt;https://github.com/pytest-dev/pytest/issues/5095&gt;`_: XML files of the ``xunit2`` family are now validated against the schema by pytest&#39;s own test suite
  to avoid future regressions.


- `5516 &lt;https://github.com/pytest-dev/pytest/issues/5516&gt;`_: Cache node splitting function which can improve collection performance in very large test suites.


- `5603 &lt;https://github.com/pytest-dev/pytest/issues/5603&gt;`_: Simplified internal ``SafeRepr`` class and removed some dead code.


- `5664 &lt;https://github.com/pytest-dev/pytest/issues/5664&gt;`_: When invoking pytest&#39;s own testsuite with ``PYTHONDONTWRITEBYTECODE=1``,
  the ``test_xfail_handling`` test no longer fails.


- `5684 &lt;https://github.com/pytest-dev/pytest/issues/5684&gt;`_: Replace manual handling of ``OSError.errno`` in the codebase by new ``OSError`` subclasses (``PermissionError``, ``FileNotFoundError``, etc.).
