Overview

External tool documentation for the version bump release script provided by the Wandb Weave repository.

Description

The bump_python_sdk_version.py script (step 1) runs bump-my-version bump pre_l ./weave/version.py --tag --commit to drop the pre-release tag from the version string. This transforms X.Y.Z-dev0 to X.Y.Z, creates a git commit, and adds a vX.Y.Z tag.

The pyproject.toml [tool.bumpversion] section defines the version parse regex and the pre_l part with values ["dev", "final"] where optional_value = "final".

Usage

Run with uv run scripts/bump_python_sdk_version.py to perform the release bump. Use --dry-run to preview changes.
