httpx2 2.12.0

v2.12.0

on Python PyPI

Highlights

🛡️ Bounded response decompression

httpx2 now decodes gzip, deflate, 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 (#1126).

📦 Shared Zstandard API

Python 3.13 and earlier now use backports.zstd, which provides the same bounded incremental decompression API as compression.zstd on Python 3.14 and later (#1146).

httpx2

Changed

• Use backports.zstd for Zstandard decoding on Python 3.13 and earlier by @Kludex in #1146

Fixed

• Bound peak memory while streaming compressed responses and close response streams when decoding fails by @Kludex in #1126

httpcore2

No changes since 2.11.0. Version bumped to stay in lockstep with httpx2.
