astral-sh/uv (uv)

v0.12.15

Compare Source

Released on 2026-09-15.

This release fixes a regression in 0.12.14 that lead to rejecting valid installation commands such as using
uv pip install --system in python:* docker images or when using uv pip install --target .. (#​21699)

Performance

• Speed up cold-cache resolution and HTTP cache revalidation by batching cache writes (#​21675)

Bug fixes

• Revert "Reject symlinked wheel installation destinations" (#​21699)

v0.12.14

Compare Source

Released on 2026-09-15.

Package-operation errors now use uv's standard diagnostics, with consistent hints and compact, labeled cause chains. (#​17110, #​21599, #​21603)

Package-operation exit codes now reflect the underlying cause: expected failures return 1, while recognized operational and internal failures return 2. (#​17110)

Enhancements

• Resume interrupted downloads with HTTP Range requests when supported (#​21570)
• Show underlying causes and hints in user warnings (#​21565)
• Show resolver hints for failed uv tool upgrade operations (#​21566)

Preview features

• Export multiple dependency selections from a shared lockfile in one uv export --batch invocation with the batch-export preview feature (#​21618)

Performance

• Speed up dependency resolution from local wheelhouses by reading wheel metadata in a single blocking task (#​21619)
• Speed up cold resolution against large package indexes by parsing Simple API responses in bounded background workers (#​21593)
• Speed up warm-cache resolution by decoding fresh HTTP cache entries in the cache-read task (#​21621)

Bug fixes

• Select releases that satisfy required-environments within each resolver fork instead of combining incompatible wheel coverage across forks (#​21672)
• Install packages with paths longer than MAX_PATH on Windows systems without long-path support enabled (#​21625)
• Prevent uv python install from overwriting valid unmanaged Python symlinks with relative targets on Unix (#​21639)
• Redact credentials and signatures from missing-path-segment URL errors (#​21616)
• Avoid exceeding the configured retry budget when cached HTTP responses fail revalidation (#​21640)
• Prefer bin/python over bin/python3 when discovering interpreters in Unix environments (#​21559)
• Suppress managed-Python fallback warnings under --quiet (#​21565)
• Keep failed uv tool upgrade errors visible with -q while suppressing them with -qq (#​21566)
