发布说明

发布于 2026-08-25。

Python

  • 更新 CPython 以使用 OpenSSL 3.5.8 和 libffi 3.4.8 #21295

增强

  • 报告文件系统块分配带来的缓存清理空间节省，并避免硬链接重复计数 (#21261)
  • 将关于无界 uv_build 要求的警告限制为源代码分发构建 (#21078)

  • 当基础解释器位于 bin 目录之外时，保留来自 tar-codec 源代码分发错误的虚拟环境提示 (#21146)

性能

  • 为 Linux x86-64 发布二进制文件启用配置文件引导优化 (#21001)
  • 为 Windows x86-64 发布二进制文件启用配置文件引导优化 (#21003)
  • 为 macOS ARM64 发布二进制文件启用配置文件引导优化 (#21002)
  • 为 Linux ARM64 发布二进制文件启用配置文件引导优化 (#21004)
  • 通过重用编码表示，加速同步包含许多已激活冲突项的项目 (#21148)

Release Notes

Released on 2026-08-25.

Python

  • Update CPython to use OpenSSL 3.5.8 and libffi 3.4.8 #21295)

Enhancements

  • Report cache-cleaning space savings from filesystem block allocation and avoid double-counting hard links (#21261)
  • Limit warnings about unbounded uv_build requirements to source-distribution builds (#21078)
  • Display byte counts below 1 KiB without a fractional part (#21237)

Preview features

  • Add uv workspace metadata --sync --exact to remove packages outside the selected resolution (#21117)
  • Add the artifact-hash-filtering preview feature to make uv pip compile --generate-hashes honor --only-binary and --no-binary (#21235)
  • Respect package-specific exclude-newer cutoffs when uv check selects its ty executable (#21227)
  • Preserve virtual-environment hints from tar-codec source-distribution errors when the base interpreter is outside a bin directory (#21146)

Performance

  • Enable profile-guided optimization for Linux x86-64 release binaries (#21001)
  • Enable profile-guided optimization for Windows x86-64 release binaries (#21003)
  • Enable profile-guided optimization for macOS ARM64 release binaries (#21002)
  • Enable profile-guided optimization for Linux ARM64 release binaries (#21004)
  • Speed up syncing projects with many activated conflict items by reusing their encoded representation (#21148)

Bug fixes

  • Allow explicit uv build and non-editable first-party workspace packages when no-build is enabled (#21294)
  • Reuse configured index credentials during uv tool upgrade when the tool receipt references the same index (#21275)
  • Ensure full 40-character Git commit pins resolve to the requested object instead of a SHA-named branch (#21224)
  • Prevent TLS segfaults in riscv64 musl release binaries (#21158)
  • Preserve dependencies selected by recursive extras when markers mix production and extra conditions (#21181)
  • Preserve version constraints from transitively referenced recursive extras (#21209)
  • Resolve repository-relative Git archive dependencies inside the checkout during the initial uv sync (#21264)
  • Return an error instead of panicking when a bearer token cannot be encoded as an HTTP header (#21282)
  • Do not misclassify package URLs ending in .py as local script paths (#21144)
  • Use directory creation times consistently across libc implementations for directory cache-keys entries (#21137)
  • Promote human-readable sizes to the next unit at rounding boundaries (#21136)

Other changes

  • Add Python 3.15 release-candidate Docker images (#21293)
  • Raise the minimum supported Rust version to 1.96 and update the repository toolchain to Rust 1.98 (#21258)
