+pytest 4.6.3 (2019-06-11)
+=========================
+
+Bug Fixes
+---------
+
+- `#5383 <https://github.com/pytest-dev/pytest/issues/5383>`_: ``-q`` has again an impact on the style of the collected items
+  (``--collect-only``) when ``--log-cli-level`` is used.
+
+
+- `#5389 <https://github.com/pytest-dev/pytest/issues/5389>`_: Fix regressions of `#5063 <https://github.com/pytest-dev/pytest/pull/5063>`__ for ``importlib_metadata.PathDistribution`` which have their ``files`` attribute being ``None``.
+
+
+- `#5390 <https://github.com/pytest-dev/pytest/issues/5390>`_: Fix regression where the ``obj`` attribute of ``TestCase`` items was no longer bound to methods.
+
+
+pytest 4.6.2 (2019-06-03)
+=========================
+
+Bug Fixes
+---------
+
+- `#5370 <https://github.com/pytest-dev/pytest/issues/5370>`_: Revert unrolling of ``all()`` to fix ``NameError`` on nested comprehensions.
+
+
+- `#5371 <https://github.com/pytest-dev/pytest/issues/5371>`_: Revert unrolling of ``all()`` to fix incorrect handling of generators with ``if``.
+
+
+- `#5372 <https://github.com/pytest-dev/pytest/issues/5372>`_: Revert unrolling of ``all()`` to fix incorrect assertion when using ``all()`` in an expression.
+
+
+pytest 4.6.1 (2019-06-02)
+=========================
+
+Bug Fixes
+---------
+
+- `#5354 <https://github.com/pytest-dev/pytest/issues/5354>`_: Fix ``pytest.mark.parametrize`` when the argvalues is an iterator.
+
+
+- `#5358 <https://github.com/pytest-dev/pytest/issues/5358>`_: Fix assertion rewriting of ``all()`` calls to deal with non-generators.
