Known issues

gotchaDefault output uses conda channels; pip-only dependencies are included via pip section in environment.yml unless --pip-only flag is used.

fix

Use --pip-only flag or configure channels in your pyproject.toml.

affects: >=0.0.0

breakingConfiguration file option names changed from dash to underscore in v0.21.0. Old config keys with dashes no longer work.

fix

Replace dashes with underscores in config file keys (e.g., 'output-file' -> 'output_file').

affects: >=0.21.0

deprecatedPython 3.9 support was dropped. Requires Python >=3.10 as of v0.22.0.

fix

Upgrade Python to 3.10 or later.

affects: >=0.22.0
