About Hatch

A modern, extensible Python project manager.

What's new in 1.18.1

Added:
- Apply context formatting to the lock-filename environment option so fields such as {env_name} and {matrix:...} are resolved when computing the lock file path.
Fixed:
- Consolidate extras and feature resolution into a single code path, fixing regressions where environment and project extras could be dropped or resolved inconsistently, and always validate undefined features.
- Normalize hyphens in the plugin name when building environment option environment variable names in get_env_var(), so options for hyphenated plugins resolve to the correct variable.
