中文处理结果

发布说明

发布于 2026-09-08。

预览功能

  • 导出 pylock.toml 文件时生成缺失的工件哈希，以确保符合 PEP 751 (#20146)
  • 当 pylock.toml 工件哈希表为空时发出警告，未来 uv 版本将拒绝此类文件 (#21462)

性能

  • 通过消除原子硬链接、符号链接和 reflink 替换的逐文件临时目录，加速覆盖现有文件的安装 (#21478)
  • 通过将逐文件临时目录替换为相邻临时文件，加速将复制的 wheel 合并到现有环境的安装 (#21468)
  • 通过用定位读取替换共享 ZIP 游标锁，加速本地 wheel 安装 (#21500)
  • 通过跨提取文件重用 ZIP 读取器和缓冲区，加速本地 wheel 安装 (#21499)
  • 当 uv pip install --no-deps 发现请求的包已安装时，避免传递依赖检查和不必要的解析 (#21523)

错误修复

  • 在读取源归档的元数据或运行其构建后端之前，根据 uv.lock 中记录的哈希验证源归档 (#21223)
  • 在 --verify-hashes 和 --require-hashes 下，验证使用 === 固定的注册表需求的提供的哈希 (#21543)
  • 当未提供精确的本地版本哈希时，将公共版本固定的哈希应用于匹配的本地版本 (#21544)
  • 支持从 UNC 路径（包括 WSL 路径）激活 PowerShell 虚拟环境 (#19159)
  • 去除 .python-version 和 .python-versions 文件中条目的周围空白 (#21529)
  • 抑制 uv add --no-sync、uv remove --no-sync 和 uv add --frozen 的 VIRTUAL_ENV 不匹配警告 (#21496)
  • 当 uv python list 无法查询解释器时发出警告并继续 (#21498)

文档

  • 恢复 exclude-newer 示例的 TOML 语法高亮 (#21534)

Release Notes

Released on 2026-09-08.

Preview features

  • Generate missing artifact hashes when exporting pylock.toml files to ensure they conform to PEP 751 (#20146)
  • Warn when pylock.toml artifact hash tables are empty, which will be rejected in a future uv release (#21462)

Performance

  • Speed up installs that overwrite existing files by eliminating per-file temporary directories for atomic hard-link, symlink, and reflink replacements (#21478)
  • Speed up installs that merge copied wheels into existing environments by replacing per-file temporary directories with adjacent temporary files (#21468)
  • Speed up local wheel installs by replacing the shared ZIP cursor lock with positioned reads (#21500)
  • Speed up local wheel installs by reusing ZIP readers and buffers across extracted files (#21499)
  • Avoid transitive dependency checks and unnecessary resolution when uv pip install --no-deps finds the requested packages already installed (#21523)

Bug fixes

  • Verify source archives against hashes recorded in uv.lock before reading their metadata or running their build backends (#21223)
  • Verify supplied hashes for registry requirements pinned with === under both --verify-hashes and --require-hashes (#21543)
  • Apply hashes from public-version pins to matching local versions when no exact local-version hash is provided (#21544)
  • Support PowerShell virtual environment activation from UNC paths, including WSL paths (#19159)
  • Trim surrounding whitespace from entries in .python-version and .python-versions files (#21529)
  • Suppress VIRTUAL_ENV mismatch warnings for uv add --no-sync, uv remove --no-sync, and uv add --frozen (#21496)
  • Warn and continue when uv python list cannot query an interpreter (#21498)

Documentation

  • Restore TOML syntax highlighting for exclude-newer examples (#21534)

Verifying GitHub Artifact Attestations

The artifacts in this release have attestations generated with GitHub Artifact Attestations. These can be verified by using the GitHub CLI:

gh attestation verify <file-path of downloaded artifact> --repo astral-sh/uv

You can also download the attestation from GitHub and verify against that directly:

gh attestation verify <file-path of downloaded artifact> --bundle <file-path of downloaded attestation>
