• This step references steps.cached-poetry-dependencies.outputs.cache-hit, but the preceding cache step has no id, so this output will be undefined. Add an id (for example id: cached-poetry-dependencies) to the cache action.

      if: steps.cached-poetry-dependencies.outputs.cache-hit != 'true'

## 2.0.0 (2025-07-04)

[Copilot]

The Ruff target-version is set only to Python 3.9 but this project now supports multiple versions; update it to include all supported versions, e.g., target-version = ["py39", "py310", "py311", "py312", "py313"].

Suggested change

	target-version = "py39"
	target-version = ["py39", "py310", "py311", "py312", "py313"]

[Copilot]

[nitpick] The package version is defined in both setup.py and pyproject.toml, which can drift out of sync. Consider centralizing version management (e.g., using version_files exclusively) to ensure a single source of truth.

Suggested change

version = "2.0.0"
