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

Bug Fixes
---------

- `3952 <https://github.com/pytest-dev/pytest/issues/3952>`_: Display warnings before "short test summary info" again, but still later warnings in the end.


- `4386 <https://github.com/pytest-dev/pytest/issues/4386>`_: Handle uninitialized exceptioninfo in repr/str.


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


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


- `4405 <https://github.com/pytest-dev/pytest/issues/4405>`_: Fix collection of testpaths with ``--pyargs``.


- `4412 <https://github.com/pytest-dev/pytest/issues/4412>`_: Fix assertion rewriting involving ``Starred`` + side-effects.

Trivial/Internal Changes
