3. Use "useCallback" to prevent double tracking when switching pages
4. Add links pre-fetching in marketing navigation
5. Add new pending state to MFA verification form
6. Pre-fetch sign-in/sign-up pages
7. Fix i18n when using regional languages
8. currency formatter should default to the region if it exists
9. Update packages
