  <summary>Changelog</summary>
  
  
   ### 2.10.1
   ```
   -------------------

* Support for ``pytest-xdist`` 2.0, which breaks compatibility with ``pytest-xdist`` before 1.22.3 (from 2017).
  Contributed by Zac Hatfield-Dodds in `412 &lt;https://github.com/pytest-dev/pytest-cov/pull/412&gt;`_.
* Fixed the ``LocalPath has no attribute startswith`` failure that occurred when using the ``pytester`` plugin
  in inline mode.
   ```
   
  
  
   ### 2.10.0
   ```
   -------------------

* Improved the ``--no-cov`` warning. Now it&#39;s only shown if ``--no-cov`` is present before ``--cov``.
* Removed legacy pytest support. Changed ``setup.py`` so that ``pytest&gt;=4.6`` is required.
   ```
   
  
  
   ### 2.9.0
