==================


* Fix issue in assertion rewriting breaking due to modules silently discarding
other modules when importing fails
Notably, importing the ``anydbm`` module is fixed. (`2248`_).
Thanks `pfhayes`_ for the PR.

* junitxml: Fix problematic case where system-out tag occured twice per testcase
element in the XML report. Thanks `kkoukiou`_ for the PR.

* Fix regression, pytest now skips unittest correctly if run with ``--pdb``
(`2137`_). Thanks to `gst`_ for the report and `mbyt`_ for the PR.

* Ignore exceptions raised from descriptors (e.g. properties) during Python test collection (`2234`_).
Thanks to `bluetech`_.

* ``--override-ini`` now correctly overrides some fundamental options like ``python_files`` (`2238`_).
Thanks `sirex`_ for the report and `nicoddemus`_ for the PR.

* Replace ``raise StopIteration`` usages in the code by simple ``returns`` to finish generators, in accordance to `PEP-479`_ (`2160`_).
Thanks `tgoodlet`_ for the report and `nicoddemus`_ for the PR.

* Fix internal errors when an unprintable ``AssertionError`` is raised inside a test.
Thanks `omerhadari`_ for the PR.

* Skipping plugin now also works with test items generated by custom collectors (`2231`_).
Thanks to `vidartf`_.

* Fix trailing whitespace in console output if no .ini file presented (`2281`_). Thanks `fbjorn`_ for the PR.

* Conditionless ``xfail`` markers no longer rely on the underlying test item
being an instance of ``PyobjMixin``, and can therefore apply to tests not
collected by the built-in python test collector. Thanks `barneygale`_ for the
PR.

==================

* pytest no longer generates ``PendingDeprecationWarning`` from its own operations, which was introduced by mistake in version ``3.0.5`` (`2118`_).
Thanks to `nicoddemus`_ for the report and `RonnyPfannschmidt`_ for the PR.


* pytest no longer recognizes coroutine functions as yield tests (`2129`_).
Thanks to `malinoff`_ for the PR.

* Plugins loaded by the ``PYTEST_PLUGINS`` environment variable are now automatically
considered for assertion rewriting (`2185`_).
Thanks `nicoddemus`_ for the PR.

* Improve error message when pytest.warns fails (`2150`_). The type(s) of the
expected warnings and the list of caught warnings is added to the
error message. Thanks `lesteve`_ for the PR.

* Fix ``pytester`` internal plugin to work correctly with latest versions of
``zope.interface`` (`1989`_). Thanks `nicoddemus`_ for the PR.

Thanks `RonnyPfannschmidt`_ for the report and `nicoddemus`_ for the PR.

* Specifying tests with colons like ``test_foo.py::test_bar`` for tests in
subdirectories with ini configuration files now uses the correct ini file
(`2148`_). Thanks `pelme`_.

* Fail ``testdir.runpytest().assert_outcomes()`` explicitly if the pytest
terminal output it relies on is missing. Thanks to `eli-b`_ for the PR.

==================

* 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`_.

==================

* Import errors when collecting test modules now display the full traceback (`1976`_).
Thanks `cwitty`_ for the report and `nicoddemus`_ for the PR.

* Fix confusing command-line help message for custom options with two or more ``metavar`` properties (`2004`_).
Thanks `okulynyak`_ and `davehunt`_ for the report and `nicoddemus`_ for the PR.

* When loading plugins, import errors which contain non-ascii messages are now properly handled in Python 2 (`1998`_).
Thanks `nicoddemus`_ for the PR.

* Fixed cyclic reference when ``pytest.raises`` is used in context-manager form (`1965`_). Also as a
result of this fix, ``sys.exc_info()`` is left empty in both context-manager and function call usages.
Previously, ``sys.exc_info`` would contain the exception caught by the context manager,
even when the expected exception occurred.
Thanks `MSeifert04`_ for the report and the PR.

* Fixed false-positives warnings from assertion rewrite hook for modules that were rewritten but
were later marked explicitly by ``pytest.register_assert_rewrite``
or implicitly as a plugin (`2005`_).
Thanks `RonnyPfannschmidt`_ for the report and `nicoddemus`_ for the PR.

* Report teardown output on test failure (`442`_).
Thanks `matclab`_ for the PR.

* Fix teardown error message in generated xUnit XML.
Thanks `gdyuldin`_ for the PR.

* Properly handle exceptions in ``multiprocessing`` tasks (`1984`_).
Thanks `adborden`_ for the report and `nicoddemus`_ for the PR.

* Clean up unittest TestCase objects after tests are complete (`1649`_).
Thanks `d_b_w`_ for the report and PR.

``VersionConflict`` errors in plugins (`704`_).
Thanks `nicoddemus`_ for the PR.
