Breaking Changes

Issue #1

The `pathspec` dependency is now restricted to versions <1, which may break projects that relied on newer versions. Update your `pathspec` requirement to <1 or adjust code to be compatible.

Migration Steps

  1. 1
    If your project depends on `pathspec` >=1, downgrade the dependency to a version <1 or modify code to work with the older API.

Release Summary

This release restricts the `pathspec` dependency to versions below 1, introduces the `--collapse-foreach-matrix` CLI option, and updates the `flufl-lock` version bounds.
