dependabot[bot]GitHubdependabot[bot] <49699333+dependabot[bot]@users.noreply.github.com>John KennedyBumps [httpx2](https://github.com/pydantic/httpx2) from 2.10.0 to 2.12.0. <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/pydantic/httpx2/releases">httpx2's releases</a>.</em></p> <blockquote> <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>.
