releases</a>.</em></p>
<blockquote>
<h2>0.0.33</h2>
<h2>Release Notes</h2>
<p>Released on 2026-04-28.</p>
<h3>Notable changes</h3>
<ul>
<li>
<p>ty now prefers the declared type of an annotated assignment in more
situations (<a
href="https://redirect.github.com/astral-sh/ruff/pull/24802">#24802</a>).
Consider this example:</p>
<pre lang="py"><code>from some_library import untyped_function
<p>threshold: int | None = 0
result: str = untyped_function()
</code></pre></p>
<p>ty previously favored the <em>inferred</em> type of the right hand
side expression when <code>threshold</code> and <code>result</code> were
used. This is useful for <code>threshold</code>, as it allows something
like <code>threshold += 1</code> to work without an error: we know that
<code>threshold</code> could later become <code>None</code>, but
<em>right now</em>, we see that it is an <code>int</code>. However, for
<code>result</code>, the inferred type is <code>Unknown</code>. This is
<em>not</em> a useful type and it can lead to false negatives. Starting
with this release, ty will therefore prefer
the declared type <em>if the inferred and declared types are mutually
assignable</em>. In the above example, <code>threshold</code> will still
be inferred as <code>int</code> (or rather <code>Literal[1]</code>), but
<code>result</code> will now be inferred as <code>str</code>. If you
previously added <code>cast</code>s to work around this behavior, you
should be able to remove them after upgrading.</p>
