<blockquote>
<h2>4.1.0 (2023-05-24)</h2>
<ul>
<li>Updated CI with new Pythons and dependencies.</li>
<li>Removed rsyncdir support. This makes pytest-cov compatible with
xdist 3.0.
Contributed by Sorin Sbarnea in
<code>[#558](pytest-dev/pytest-cov#558)
&lt;https://github.com/pytest-dev/pytest-cov/pull/558&gt;</code>_.</li>
<li>Optimized summary generation to not be performed if no reporting is
active (for example,
when <code>--cov-report=''</code> is used without
<code>--cov-fail-under</code>).
Contributed by Jonathan Stewmon in
<code>[#589](pytest-dev/pytest-cov#589)
&lt;https://github.com/pytest-dev/pytest-cov/pull/589&gt;</code>_.</li>
<li>Added support for JSON reporting.
Contributed by Matthew Gamble in
<code>[#582](pytest-dev/pytest-cov#582)
&lt;https://github.com/pytest-dev/pytest-cov/pull/582&gt;</code>_.</li>
<li>Refactored code to use f-strings.
Contributed by Mark Mayo in
<code>[#572](pytest-dev/pytest-cov#572)
&lt;https://github.com/pytest-dev/pytest-cov/pull/572&gt;</code>_.</li>
<li>Fixed a skip in the test suite for some old xdist.
Contributed by a bunch of people in
<code>[#565](pytest-dev/pytest-cov#565)
&lt;https://github.com/pytest-dev/pytest-cov/pull/565&gt;</code>_.</li>
</ul>
<h2>4.0.0 (2022-09-28)</h2>
<p><strong>Note that this release drops support for
multiprocessing.</strong></p>
<ul>
<li>
<p><code>--cov-fail-under</code> no longer causes <code>pytest
--collect-only</code> to fail
Contributed by Zac Hatfield-Dodds in
<code>[#511](pytest-dev/pytest-cov#511)
&lt;https://github.com/pytest-dev/pytest-cov/pull/511&gt;</code>_.</p>
</li>
<li>
<p>Dropped support for multiprocessing (mostly because <code>issue 82408
&lt;https://github.com/python/cpython/issues/82408&gt;</code>_). This
feature was
mostly working but very broken in certain scenarios and made the test
suite very flaky and slow.</p>
<p>There is builtin multiprocessing support in coverage and you can
migrate to that. All you need is this in your
<code>.coveragerc</code>::</p>
<p>[run]
concurrency = multiprocessing
parallel = true
sigterm = true</p>
</li>
<li>
<p>Fixed deprecation in <code>setup.py</code> by trying to import
setuptools before distutils.
Contributed by Ben Greiner in
<code>[#545](pytest-dev/pytest-cov#545)
&lt;https://github.com/pytest-dev/pytest-cov/pull/545&gt;</code>_.</p>
</li>
<li>
<p>Removed undesirable new lines that were displayed while reporting was
disabled.
Contributed by Delgan in
<code>[#540](pytest-dev/pytest-cov#540)
&lt;https://github.com/pytest-dev/pytest-cov/pull/540&gt;</code>_.</p>
</li>
<li>
<p>Documentation fixes.

<code>[#543](pytest-dev/pytest-cov#543)

and Colin O'Dell in
<code>[#525](pytest-dev/pytest-cov#525)
&lt;https://github.com/pytest-dev/pytest-cov/pull/525&gt;</code>_.</p>
</li>
<li>
<p>Added support for LCOV output format via
<code>--cov-report=lcov</code>. Only works with coverage 6.3+.
Contributed by Christian Fetzer in
<code>[#536](pytest-dev/pytest-cov#536)
&lt;https://github.com/pytest-dev/pytest-cov/issues/536&gt;</code>_.</p>
</li>
<li>
