   ### 2.8.1
   ```
   ------------------

* Fixed `348 &lt;https://github.com/pytest-dev/pytest-cov/issues/348&gt;`_ -
  regression when only certain reports (html or xml) are used then ``--cov-fail-under`` always fails.
   ```
   
  
  
   ### 2.8.0
   ```
   ------------------

* Fixed ``RecursionError`` that can occur when using
  `cleanup_on_signal &lt;https://pytest-cov.readthedocs.io/en/latest/subprocess-support.htmlif-you-got-custom-signal-handling&gt;`__ or
  `cleanup_on_sigterm &lt;https://pytest-cov.readthedocs.io/en/latest/subprocess-support.htmlif-you-got-custom-signal-handling&gt;`__.
  See: `294 &lt;https://github.com/pytest-dev/pytest-cov/issues/294&gt;`_.
  The 2.7.x releases of pytest-cov should be considered broken regarding aforementioned cleanup API.

  (match pytest-xdist master/worker terminology).
