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).

Changed
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.
