<h1>Mypy Release Notes</h1>
<h2>Next Release</h2>
<h2>Mypy 1.16</h2>
<p>We’ve just uploaded mypy 1.16 to the Python Package Index (<a
href="https://pypi.org/project/mypy/">PyPI</a>).
Mypy is a static type checker for Python. This release includes new
features and bug fixes.
You can install it as follows:</p>
<pre><code>python3 -m pip install -U mypy
</code></pre>
<p>You can read the full documentation for this release on <a
href="http://mypy.readthedocs.io">Read the Docs</a>.</p>
<h3>Different Property Getter and Setter Types</h3>
<p>Mypy now supports using different types for a property getter and
setter:</p>
<pre lang="python"><code>class A:
    _value: int
<pre><code>@Property
def foo(self) -&amp;gt; int:
    return self._value

@foo.setter
def foo(self, x: str | int) -&amp;gt; None:
    try:
        self._value = int(x)
    except ValueError:
raise Exception(f&amp;quot;'{x}' is not a valid value for
'foo'&amp;quot;)
</code></pre>
<p></code></pre></p>
<p>This was contributed by Ivan Levkivskyi (PR <a
href="https://redirect.github.com/python/mypy/pull/18510">18510</a>).</p>
<h3>Flexible Variable Redefinitions (Experimental)</h3>
<p>Mypy now allows unannotated variables to be freely redefined with
different types when using the experimental
<code>--allow-redefinition-new</code>
flag. You will also need to enable <code>--local-partial-types</code>.
Mypy will
now infer a union type when different types are assigned to a
variable:</p>
<pre lang="py"><code># mypy: allow-redefinition-new, local-partial-types
<p>def f(n: int, b: bool) -&gt; int | str:
if b:
x = n
else:
&lt;/tr&gt;&lt;/table&gt;
</code></pre></p>
