pytest 6.2.3 (2021-04-03)
=========================

Bug Fixes
---------

- pytest used to create directories under ``/tmp`` with world-readable
  permissions. This means that any user in the system was able to read
  information written by tests in temporary directories (such as those created by
  the ``tmp_path``/``tmpdir`` fixture). Now the directories are created with
  private permissions.

  pytest used silenty use a pre-existing ``/tmp/pytest-of-<username>`` \ 
directory,
  even if owned by another user. This means another user could pre-create such a
  directory and gain control of another user's temporary directory. Now such a
  condition results in an error.
