<h2>v2.12.0</h2>
<h2>Highlights</h2>
<h3>🛡️ Bounded response decompression</h3>
<p><code>httpx2</code> now decodes <code>gzip</code>,
<code>deflate</code>, Brotli, and Zstandard responses incrementally.
Each decode step emits at most 1 MiB, so streaming a highly compressed
response no longer requires materializing an entire inflated network
chunk in memory (<a
href="https://redirect.github.com/pydantic/httpx2/pull/1126">pydantic/httpx2#1126</a>).</p>
<h3>📦 Shared Zstandard API</h3>
<p>Python 3.13 and earlier now use <code>backports.zstd</code>, which
provides the same bounded incremental decompression API as
<code>compression.zstd</code> on Python 3.14 and later (<a
href="https://redirect.github.com/pydantic/httpx2/pull/1146">pydantic/httpx2#1146</a>).</p>
<h2>httpx2</h2>
<h3>Changed</h3>
<ul>
<li>Use <code>backports.zstd</code> for Zstandard decoding on Python
3.13 and earlier by <a
href="https://github.com/Kludex"><code>@​Kludex</code></a> in <a
href="https://redirect.github.com/pydantic/httpx2/pull/1146">pydantic/httpx2#1146</a></li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Bound peak memory while streaming compressed responses and close
response streams when decoding fails by <a
href="https://github.com/Kludex"><code>@​Kludex</code></a> in <a
href="https://redirect.github.com/pydantic/httpx2/pull/1126">pydantic/httpx2#1126</a></li>
</ul>
<h2>httpcore2</h2>
<p>No changes since <code>2.11.0</code>. Version bumped to stay in
lockstep with <code>httpx2</code>.</p>
<p><strong>Full Changelog</strong>: <a

<h2>v2.11.0</h2>
<h2>Highlights</h2>
<h3>🌐 Public origin API</h3>
<p><code>httpx2</code> now includes an immutable and hashable
<code>Origin</code> value object, available through
<code>URL.origin</code>. It provides normalized scheme, host, and
effective port comparisons without including URL paths, queries,
fragments, or credentials (<a
href="https://redirect.github.com/pydantic/httpx2/pull/1134">pydantic/httpx2#1134</a>).</p>
<h3>🛠️ Request compatibility and validation</h3>
<ul>
<li>Explicit <code>Transfer-Encoding</code> headers now take precedence
over body-derived <code>Content-Length</code> headers (<a
href="https://redirect.github.com/pydantic/httpx2/pull/1137">pydantic/httpx2#1137</a>).</li>
<li>Deprecated status code aliases are available again (<a
href="https://redirect.github.com/pydantic/httpx2/pull/1135">pydantic/httpx2#1135</a>).</li>
<li>Multipart part headers are validated before serialization (<a
href="https://redirect.github.com/pydantic/httpx2/pull/1142">pydantic/httpx2#1142</a>).</li>
</ul>
<h2>httpx2</h2>
<h3>Added</h3>
<ul>
<li>Add the public <code>Origin</code> value object and
<code>URL.origin</code> property by <a
href="https://github.com/Kludex"><code>@​Kludex</code></a> in <a
href="https://redirect.github.com/pydantic/httpx2/pull/1134">pydantic/httpx2#1134</a></li>
</ul>
<h3>Changed</h3>
<ul>
<li>Require Brotli 1.2.0 or later for the <code>brotli</code> extra by
<a href="https://github.com/Kludex"><code>@​Kludex</code></a> in <a
href="https://redirect.github.com/pydantic/httpx2/pull/1141">pydantic/httpx2#1141</a></li>
