2.8.1

------------------

* Fixed `348 <https://github.com/pytest-dev/pytest-cov/issues/348>`_ -
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 <https://pytest-cov.readthedocs.io/en/latest/subprocess-support.htmlif-you-got-custom-signal-handling>`__ or
`cleanup_on_sigterm <https://pytest-cov.readthedocs.io/en/latest/subprocess-support.htmlif-you-got-custom-signal-handling>`__.
See: `294 <https://github.com/pytest-dev/pytest-cov/issues/294>`_.
The 2.7.x releases of pytest-cov should be considered broken regarding aforementioned cleanup API.

(match pytest-xdist master/worker terminology).

Contributed by Thomas Grainger in `338 <https://github.com/pytest-dev/pytest-cov/pull/338>`_.
