- Fixed navigation/link handling: correct <a href> generation, NavLink root URL behavior, relative=path support, and formAction pathnames for index routes
- Improved router behavior: useRoutes can return null, corrected initialEntries type, added basename/relative support for redirects, and ignored pathless layout routes for submissions
- Added UMD build for @remix‑run/router, fixed createURL in Firefox, and enhanced special‑character encoding/matching
