This release adds preliminary support for the PEP 751 `pylock.toml` format across export, compile, install, and sync commands, introduces several new environment variables and enhancements, and includes numerous bug fixes and documentation updates.

✨ New Features

  • Preliminary support for the `pylock.toml` file format (PEP 751) with export, compile, install and sync commands.
  • Added `UV_NO_EDITABLE` environment variable to globally set `--no-editable` on all invocations.
  • `uv export` now supports PEP 751 and can infer output type.
  • CLI now accepts `requirements.txt` verbatim as a format.
  • Added a brief sleep before sending SIGINT to child processes.
  • Upload time added to `uv.lock` files.
  • Git sources can be updated by name.
  • `uv init` caches the result of `which git`.
  • `--dry-run` now works with `--locked`/`--frozen` for `uv sync`.
  • `uv init` is resilient against broken git installations.
  • `uv run --with` now respects build constraints for dependencies.
  • `UV_INDEX` is split on all whitespace.
  • Build constraints are supported in `uv tool` and PEP723 scripts.
  • When searching for the uv binary, the suffix from the `uvx` binary is used.
  • Version formatting now uses cyan color.
  • Debug logs added for version file search.
  • Passwords are obfuscated in credentials debug messages.
  • Possible tokens are obfuscated in URL logs.

  • Preview feature: Build backend reference documentation and schema.
