<blockquote>
<h2>Version 7.6.8 — 2024-11-23</h2>
<ul>
<li>
<p>Fix: the LCOV report code assumed that a branch line that took no
branches
meant that the entire line was unexecuted. This isn't true in a few
cases:
the line might always raise an exception, or might have been optimized
away.
Fixes <code>issue 1896</code>_.</p>
</li>
<li>
<p>Fix: similarly, the HTML report will now explain that a line that
jumps to
none of its expected destinations must have always raised an exception.
Previously, it would say something nonsensical like, &quot;line 4 didn't
jump to
line 5 because line 4 was never true, and it didn't jump to line 7
because
line 4 was always true.&quot; This was also shown in <code>issue
1896</code>_.</p>
</li>
</ul>
<p>.. _issue 1896: <a
href="https://redirect.github.com/nedbat/coveragepy/issues/1896">nedbat/coveragepy#1896</a></p>
<p>.. _changes_7-6-7:</p>
<h2>Version 7.6.7 — 2024-11-15</h2>
<ul>
<li>Fix: ugh, the other assert from 7.6.5 can also be encountered in the
wild,
so it's been restored to a conditional.  Sorry for the churn.</li>
</ul>
<p>.. _changes_7-6-6:</p>
<h2>Version 7.6.6 — 2024-11-15</h2>
<ul>
<li>One of the new asserts from 7.6.5 caused problems in real projects,
as
reported in <code>issue 1891</code>_.  The assert has been removed.</li>
</ul>
<p>.. _issue 1891: <a
href="https://redirect.github.com/nedbat/coveragepy/issues/1891">nedbat/coveragepy#1891</a></p>
<p>.. _changes_7-6-5:</p>
<h2>Version 7.6.5 — 2024-11-14</h2>
<ul>
<li>
<p>Fix: fine-tuned the exact Python version (3.12.6) when exiting from
<code>with</code>
statements changed how they traced. This affected whether people saw the
fix for <code>issue 1880</code>_.</p>
</li>
<li>
<p>Fix: isolate our code more from mocking in the os module that in rare
cases
can cause <code>bizarre behavior &lt;pytest-cov-666_&gt;</code>_.</p>
</li>
<li>
<p>Refactor: some code unreachable code paths in parser.py were changed
to</p>
</li>
</ul>
