- Fix numerous ActiveSupport and ActiveRecord bugs: cache store options, enum conflict warnings, autosave handling, insert_all unique‑by guard, preload/eager load ordering, index comment preservation, and lock version bump for counter caches;
- Improve security: CSRF tokens now accept URL‑safe Base64 encoding while preserving backward compatibility, and signed/encrypted cookies can store false values;
- Add minor enhancements: update ActionView sanitization safe‑list, allow relative test paths with trailing slashes, and return 405 for unknown HTTP methods.
