+pytest 3.10.0 (2018-11-03)
+==========================
+
+Features
+--------
+
+- `#2619 <https://github.com/pytest-dev/pytest/issues/2619>`_: Resume capturing output after ``continue`` with ``__import__("pdb").set_trace()``.
+
+  This also adds a new ``pytest_leave_pdb`` hook, and passes in ``pdb`` to the
+  existing ``pytest_enter_pdb`` hook.
+
+
+- `#4147 <https://github.com/pytest-dev/pytest/issues/4147>`_: Add ``-sw``, ``--stepwise`` as an alternative to ``--lf -x`` for stopping at the first failure, but starting the next test invocation from that test.  See `the documentation <https://docs.pytest.org/en/latest/cache.html#stepwise>`__ for more info.
+
+
+- `#4188 <https://github.com/pytest-dev/pytest/issues/4188>`_: Make ``--color`` emit colorful dots when not running in verbose mode. Earlier, it would only colorize the test-by-test output if ``--verbose`` was also passed.
+
+
+- `#4225 <https://github.com/pytest-dev/pytest/issues/4225>`_: Improve performance with collection reporting in non-quiet mode with terminals.
+
+  The "collecting …" message is only printed/updated every 0.5s.
+
+
+
+Bug Fixes
+---------
+
+- `#2701 <https://github.com/pytest-dev/pytest/issues/2701>`_: Fix false ``RemovedInPytest4Warning: usage of Session... is deprecated, please use pytest`` warnings.
+
+
+- `#4046 <https://github.com/pytest-dev/pytest/issues/4046>`_: Fix problems with running tests in package ``__init__.py`` files.
+
+
+- `#4260 <https://github.com/pytest-dev/pytest/issues/4260>`_: Swallow warnings during anonymous compilation of source.
+
+
+- `#4262 <https://github.com/pytest-dev/pytest/issues/4262>`_: Fix access denied error when deleting stale directories created by ``tmpdir`` / ``tmp_path``.
+
+
+- `#611 <https://github.com/pytest-dev/pytest/issues/611>`_: Naming a fixture ``request`` will now raise a warning: the ``request`` fixture is internal and
+  should not be overwritten as it will lead to internal errors.
+
+
+
+Improved Documentation
+----------------------
+
+- `#4255 <https://github.com/pytest-dev/pytest/issues/4255>`_: Added missing documentation about the fact that module names passed to filter warnings are not regex-escaped.
+
+
+
+Trivial/Internal Changes
+------------------------
+
+- `#4272 <https://github.com/pytest-dev/pytest/issues/4272>`_: Display cachedir also in non-verbose mode if non-default.
+
+
+- `#4277 <https://github.com/pytest-dev/pytest/issues/4277>`_: pdb: improve message about output capturing with ``set_trace``.
+
+  Do not display "IO-capturing turned off/on" when ``-s`` is used to avoid
+  confusion.
+
+
+- `#4279 <https://github.com/pytest-dev/pytest/issues/4279>`_: Improve message and stack level of warnings issued by ``monkeypatch.setenv`` when the value of the environment variable is not a ``str``.

+Stepwise
+--------
+
+As an alternative to ``--lf -x``, especially for cases where you expect a large part of the test suite will fail, ``--sw``, ``--stepwise`` allows you to fix them one at a time. The test suite will run until the first failure and then stop. At the next invocation, tests will continue from the last failing test and then run until the next failing test. You may use the ``--stepwise-skip`` option to ignore one failing test and stop the test execution on the second failing test instead. This is useful if you get stuck on a failing test and just want to ignore it until later.
