Added

• Windows support by isolating platform-specific terminal code.

[0.11.0.0] - 2025-09-29

This is technically a breaking change, but if you don't use any opt-env-conf internals, nothing should break for you.

Changed

• ParserMany and ParserSome can now carry source locations. This is not likely to happen often because the Alternative class does not have a HasCallStack super class, but could still happen when using someNonEmpty.
