+pytest 4.0.1 (2018-11-23)
+=========================
+
+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.
+
+
+- `#4425 <https://github.com/pytest-dev/pytest/issues/4425>`_: Ensure we resolve the absolute path when the given ``--basetemp`` is a relative path.
+
+
+
+Trivial/Internal Changes
+------------------------
+
+- `#4315 <https://github.com/pytest-dev/pytest/issues/4315>`_: Use ``pkg_resources.parse_version`` instead of ``LooseVersion`` in minversion check.
+
+
+- `#4440 <https://github.com/pytest-dev/pytest/issues/4440>`_: Adjust the stack level of some internal pytest warnings.
