The ``4.6.X`` series will be the last series to support **Python 2 and Python 3.4**.
For more details, see our `Python 2.7 and 3.4 support plan <https://docs.pytest.org/en/latest/py27-py34-deprecation.html>`__.
Features
--------
- `4559 <https://github.com/pytest-dev/pytest/issues/4559>`_: Added the ``junit_log_passing_tests`` ini value which can be used to enable or disable logging of passing test output in the Junit XML file.
- `4956 <https://github.com/pytest-dev/pytest/issues/4956>`_: pytester's ``testdir.spawn`` uses ``tmpdir`` as HOME/USERPROFILE directory.
- `5062 <https://github.com/pytest-dev/pytest/issues/5062>`_: Unroll calls to ``all`` to full for-loops with assertion rewriting for better failure messages, especially when using Generator Expressions.
- `5063 <https://github.com/pytest-dev/pytest/issues/5063>`_: Switch from ``pkg_resources`` to ``importlib-metadata`` for entrypoint detection for improved performance and import time.
- `5091 <https://github.com/pytest-dev/pytest/issues/5091>`_: The output for ini options in ``--help`` has been improved.
- `5269 <https://github.com/pytest-dev/pytest/issues/5269>`_: ``pytest.importorskip`` includes the ``ImportError`` now in the default ``reason``.
- `5311 <https://github.com/pytest-dev/pytest/issues/5311>`_: Captured logs that are output for each failing test are formatted using the
ColoredLevelFormatter.
- `5312 <https://github.com/pytest-dev/pytest/issues/5312>`_: Improved formatting of multiline log messages in Python 3.
Bug Fixes
---------
- `2064 <https://github.com/pytest-dev/pytest/issues/2064>`_: The debugging plugin imports the wrapped ``Pdb`` class (``--pdbcls``) on-demand now.
- `4908 <https://github.com/pytest-dev/pytest/issues/4908>`_: The ``pytest_enter_pdb`` hook gets called with post-mortem (``--pdb``).
- `5036 <https://github.com/pytest-dev/pytest/issues/5036>`_: Fix issue where fixtures dependent on other parametrized fixtures would be erroneously parametrized.
- `5256 <https://github.com/pytest-dev/pytest/issues/5256>`_: Handle internal error due to a lone surrogate unicode character not being representable in Jython.
- `5257 <https://github.com/pytest-dev/pytest/issues/5257>`_: Ensure that ``sys.stdout.mode`` does not include ``'b'`` as it is a text stream.

- `5286 <https://github.com/pytest-dev/pytest/issues/5286>`_: Fix issue with ``disable_test_id_escaping_and_forfeit_all_rights_to_community_support`` option not working when using a list of test IDs in parametrized tests.
- `5330 <https://github.com/pytest-dev/pytest/issues/5330>`_: Show the test module being collected when emitting ``PytestCollectionWarning`` messages for
test classes with ``__init__`` and ``__new__`` methods to make it easier to pin down the problem.
- `5333 <https://github.com/pytest-dev/pytest/issues/5333>`_: Fix regression in 4.5.0 with ``--lf`` not re-running all tests with known failures from non-selected tests.
