<blockquote>
<h2>2.11.0 (2021-01-18)</h2>
<ul>
<li>Bumped minimum coverage requirement to 5.2.1. This prevents reporting issues.
Contributed by Mateus Berardo de Souza Terra in <code>[#433](pytest-dev/pytest-cov#433) &lt;https://github.com/pytest-dev/pytest-cov/pull/433&gt;</code>_.</li>
<li>Improved sample projects (from the <code>examples &lt;https://github.com/pytest-dev/pytest-cov/tree/master/examples&gt;</code>_
directory) to support running <code>tox -e pyXY</code>. Now the example configures a suffixed coverage data file,
and that makes the cleanup environment unnecessary.
Contributed by Ganden Schaffner in <code>[#435](pytest-dev/pytest-cov#435) &lt;https://github.com/pytest-dev/pytest-cov/pull/435&gt;</code>_.</li>
<li>Removed the empty <code>console_scripts</code> entrypoint that confused some Gentoo build script.
I didn't ask why it was so broken cause I didn't want to ruin my day.
Contributed by Michał Górny in <code>[#434](pytest-dev/pytest-cov#434) &lt;https://github.com/pytest-dev/pytest-cov/pull/434&gt;</code>_.</li>
<li>Fixed the missing <code>coverage context &lt;https://coverage.readthedocs.io/en/stable/contexts.html&gt;</code>_
when using subprocesses.
Contributed by Bernát Gábor in <code>[#443](pytest-dev/pytest-cov#443) &lt;https://github.com/pytest-dev/pytest-cov/pull/443&gt;</code>_.</li>
<li>Updated the config section in the docs.
Contributed by Pamela McA'Nulty in <code>[#429](pytest-dev/pytest-cov#429) &lt;https://github.com/pytest-dev/pytest-cov/pull/429&gt;</code>_.</li>
<li>Migrated CI to travis-ci.com (from .org).</li>
