<blockquote>
<h2>4.12.2</h2>
<ul>
<li>Fix regression in v4.12.0 where specialization of certain generics
with an overridden <code>__eq__</code> method would raise errors. Patch
by Jelle Zijlstra.</li>
<li>Fix tests so they pass on 3.13.0b2</li>
</ul>
<h2>4.12.1</h2>
<ul>
<li>Preliminary changes for compatibility with the draft implementation
of PEP 649 in Python 3.14. Patch by Jelle Zijlstra.</li>
<li>Fix regression in v4.12.0 where nested <code>Annotated</code> types
would cause
<code>TypeError</code> to be raised if the nested <code>Annotated</code>
type had unhashable
metadata. Patch by Alex Waygood.</li>
</ul>
<h2>4.12.0</h2>
<p>This release focuses on compatibility with the upcoming release of
Python 3.13. Most changes are related to the implementation of type
parameter defaults (PEP 696).</p>
<p>Thanks to all of the people who contributed patches, especially Alex
Waygood, who did most of the work adapting typing-extensions to the
CPython PEP 696 implementation.</p>
<p>There is a single change since 4.12.0rc1:</p>
<ul>
<li>Fix incorrect behaviour of <code>typing_extensions.ParamSpec</code>
on Python 3.8 and
3.9 that meant that
<code>isinstance(typing_extensions.ParamSpec(&quot;P&quot;),
typing.TypeVar)</code> would have a
different result in some situations depending on whether or not a
profiling
function had been set using <code>sys.setprofile</code>. Patch by Alex
Waygood.</li>
</ul>
<p>Changes included in 4.12.0rc1:</p>
<ul>
<li>Improve the implementation of type parameter defaults (PEP 696)
<ul>
<li>Backport the <code>typing.NoDefault</code> sentinel object from
Python 3.13.
TypeVars, ParamSpecs and TypeVarTuples without default values now have
their <code>__default__</code> attribute set to this sentinel
value.</li>
<li>TypeVars, ParamSpecs and TypeVarTuples now have a
<code>has_default()</code>
method, matching <code>typing.TypeVar</code>,
<code>typing.ParamSpec</code> and
<code>typing.TypeVarTuple</code> on Python 3.13+.</li>
<li>TypeVars, ParamSpecs and TypeVarTuples with
<code>default=None</code> passed to
their constructors now have their <code>__default__</code> attribute set
to <code>None</code>
at runtime rather than <code>types.NoneType</code>.</li>
<li>Fix most tests for <code>TypeVar</code>, <code>ParamSpec</code> and
<code>TypeVarTuple</code> on Python
3.13.0b1 and newer.</li>
<li>Backport CPython PR <a
href="https://redirect.github.com/python/cpython/pull/118774">#118774</a>,
allowing type parameters without default values to follow those with
default values in some type parameter lists. Patch by Alex Waygood,
backporting a CPython PR by Jelle Zijlstra.</li>
<li>It is now disallowed to use a <code>TypeVar</code> with a default
value after a
<code>TypeVarTuple</code> in a type parameter list. This matches the
CPython
implementation of PEP 696 on Python 3.13+.</li>
<li>Fix bug in PEP-696 implementation where a default value for a
<code>ParamSpec</code></li>
</ul>
</li>
</ul>
