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)

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)
