<blockquote>
<h1>3.0.2 (2023-08-27)</h1>
<h2>Bugs fixed</h2>
<ul>
<li>
<p>Using <code>None</code> as default value for arguments annotated as
<code>int</code> could crash Cython.
(Github issue :issue:<code>5643</code>)</p>
</li>
<li>
<p>Default values of fused types that include <code>complex</code> could
generate invalid C code
with <code>-DCYTHON_CCOMPLEX=0</code>.
(Github issue :issue:<code>5644</code>)</p>
</li>
<li>
<p>Using C++ enum class types in extension type method signatures could
generate invalid C code.
(Github issue :issue:<code>5637</code>)</p>
</li>
</ul>
<h1>3.0.1 (2023-08-25)</h1>
<h2>Features added</h2>
<ul>
<li>The error messages regarding exception declarations were improved in
order to give
better help about possible reasons and fixes.
(Github issue :issue:<code>5547</code>)</li>
</ul>
<h2>Bugs fixed</h2>
<ul>
<li>
<p>Memory view types in Python argument annotations no longer accept
<code>None</code>. They now
require an explicit <code>Optional[]</code> or a <code>None</code>
default value in order to allow <code>None</code>
to be passed. This was an oversight in the 3.0.0 release and is a
BACKWARDS INCOMPATIBLE
change. However, since it only applies to code using Python syntax, it
probably only
applies to newly written code that was written for Cython 3.0 and can
easily be adapted.
In most cases, we expect that this change will avoid bugs in user code
rather than
produce problems.
(Github issue :issue:<code>5612</code>)</p>
</li>
<li>
<p><code>nogil</code> functions using parallel code could freeze when
called with the GIL held.
(Github issues :issue:<code>5564</code>, :issue:<code>5573</code>)</p>
</li>
<li>
<p>Relative cimports could end up searching globally and find the same
package installed
elsewhere, potentially in another version.
(Github issue :issue:<code>5511</code>)</p>
</li>
<li>
<p>Attribute lookups on known standard library modules could
accidentally search
in the module namespace instead.
(Github issue :issue:<code>5536</code>)</p>
