Log message:
py-test4: added version 4.6.10

pytest 4.6.10:

Features
- New ``Config.invocation_args`` attribute containing the unchanged arguments \ 
passed to ``pytest.main()``.
  Remark: while this is technically a new feature and according to our `policy \ 
<https://docs.pytest.org/en/latest/py27-py34-deprecation.html#what-goes-into-4-6-x-releases>`_ \ 
it should not have been backported, we have opened an exception in this \ 
particular case because it fixes a serious interaction with ``pytest-xdist``, so \ 
it can also be considered a bugfix.

Trivial/Internal Changes
- Remove usage of ``parser`` module, deprecated in Python 3.9.

pytest 4.6.9:

Bug Fixes
- Fix assertion rewriting for egg-based distributions and ``editable`` installs \ 
(``pip install --editable``).

pytest 4.6.8:

Features
- JUnit XML now includes a timestamp and hostname in the testsuite tag.

Bug Fixes
- junitxml: Logs for failed test are now passed to junit report in case the test \ 
fails during call phase.

Trivial/Internal Changes
- Pin ``colorama`` to ``0.4.1`` only for Python 3.4 so newer Python versions can \ 
still receive colorama updates.

pytest 4.6.7:

Bug Fixes
- The XML file produced by ``--junitxml`` now correctly contain a \ 
``<testsuites>`` root element.
-  Properly ignore ``FileNotFoundError`` (``OSError.errno == NOENT`` in Python \ 
2) exceptions when trying to remove old temporary directories,
  for instance when multiple processes try to remove the same directory (common \ 
with ``pytest-xdist``
  for example).
