发布说明

发布于 2026-09-29。

Python

  • 更新 CPython 以使用 OpenSSL 3.5.9（#22076）

增强

  • 对于仅包含 manifest 子表的锁文件，省略空的 [manifest] 表（#22070）

预览功能

  • 借助 resolution-inputs 预览功能，从 uv.lock 中省略冗余的运行时约束，包括涉及预发布版本的约束（#22004、#22068）

缺陷修复

  • 防止 uv python pin --rm 在未指定 --global 时删除全局 .python-versions 文件（#21992）
  • 修复已安装包检查错误地将后发布版本报告为与预发布版本的排他性下界不兼容的问题（#22049）
