Compatibility notes

Version 2026100701 adds the missing people → person and children → child singularization rules, including compound suffixes such as salespeople and grandchildren. Lowercase, title-case, and uppercase forms of those suffixes retain their case. Other words continue to use the upstream cruet rules.

Older community binaries may retain the previous behavior until the fixed source is published.
