发布说明

发布于 2026-09-24。

Python

  • 新增 PyPy 3.11.16 和 3.12.14（#21847）
  • 将 GraalPy 3.13.0 更新至构建版本 25.4.4（#21847）

增强

  • 在 uv publish 错误信息中用反引号格式化上传 URL（#21934）

预览功能

  • 在 CPython 3.15 及更高版本上，通过 build-lazy-imports 预览功能以惰性导入方式运行构建后端钩子（#21967）
  • 通过 resolution-inputs 预览功能，从 uv.lock 中省略未使用的解析设置，并在检查锁文件新鲜度时忽略对这些设置的更改（#21913）

缺陷修复

  • 在直接 URL 元数据中保留带签名和编码的查询参数，避免重新安装未变更的包（#21971）
  • 在已安装包检查中，识别 1.0.0 满足 ===1，与解析行为保持一致（#21931）
  • 避免 Git 检出就绪标记与依赖中的 .ok 文件发生冲突（#21891）
  • 在解析始终为假的 python_version 标记的序列化形式时保留该标记（#21939）

Rust API

  • 恢复公开的 FlatDistributions 导出及其 BTreeMap 转换，供下游解析器使用（#21965）

文档

  • 使各个预览功能参考条目可按名称链接（#21950）

Release Notes

Released on 2026-09-24.

Python

  • Add PyPy 3.11.16 and 3.12.14 (#21847)
  • Update GraalPy 3.13.0 to build 25.4.4 (#21847)

Enhancements

  • Format upload URLs with backticks in uv publish errors (#21934)

Preview features

  • Run build-backend hooks with lazy imports on CPython 3.15 and later using the build-lazy-imports preview feature (#21967)
  • Omit unused resolution settings from uv.lock and ignore changes to them when checking lockfile freshness with the resolution-inputs preview feature (#21913)

Bug fixes

  • Preserve signed and encoded query parameters in direct-URL metadata to avoid reinstalling unchanged packages (#21971)
  • Recognize 1.0.0 as satisfying ===1 during installed-package checks, matching resolution (#21931)
  • Avoid collisions between Git checkout readiness markers and .ok files in dependencies (#21891)
  • Preserve always-false python_version markers when parsing their serialized form (#21939)

Rust API

  • Restore the public FlatDistributions export and its BTreeMap conversion for downstream resolvers (#21965)

Documentation

  • Make individual preview-feature reference entries linkable by name (#21950)
