What’s new

- Nearby Mass Times now searches a wider area, so you're less likely to see "tomorrow morning" when a real evening Mass is available a bit further away
- Today's Mass Readings now has a quick EN/ES switch right on the Today tab, so you can read in either language without leaving the screen
