   ### 4.0.1
   ```
   =========================

Bug Fixes
---------

- `3952 &lt;https://github.com/pytest-dev/pytest/issues/3952&gt;`_: Display warnings before &quot;short test summary info&quot; again, but still later warnings in the end.


- `4386 &lt;https://github.com/pytest-dev/pytest/issues/4386&gt;`_: Handle uninitialized exceptioninfo in repr/str.


- `4393 &lt;https://github.com/pytest-dev/pytest/issues/4393&gt;`_: Do not create ``.gitignore``/``README.md`` files in existing cache directories.


- `4400 &lt;https://github.com/pytest-dev/pytest/issues/4400&gt;`_: Rearrange warning handling for the yield test errors so the opt-out in 4.0.x correctly works.


- `4405 &lt;https://github.com/pytest-dev/pytest/issues/4405&gt;`_: Fix collection of testpaths with ``--pyargs``.


- `4412 &lt;https://github.com/pytest-dev/pytest/issues/4412&gt;`_: Fix assertion rewriting involving ``Starred`` + side-effects.


- `4425 &lt;https://github.com/pytest-dev/pytest/issues/4425&gt;`_: Ensure we resolve the absolute path when the given ``--basetemp`` is a relative path.



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

- `4315 &lt;https://github.com/pytest-dev/pytest/issues/4315&gt;`_: Use ``pkg_resources.parse_version`` instead of ``LooseVersion`` in minversion check.


- `4440 &lt;https://github.com/pytest-dev/pytest/issues/4440&gt;`_: Adjust the stack level of some internal pytest warnings.
