New version 4.1.2 → 4.1.3

Explore Tidal Currents Further! You can now explore Tidal Currents beyond the weather forecast period, independently of your selected weather model. A new shortcut makes them easier to access from the Weather screen. Weather and SFO data can also be hidden for a clearer chart view. Anchor Watch Improvement: • Your existing trail is preserved when Anchor Watch starts. • Default radius is 30 m and remembers your last setting. • Smoother editing: no handle jumping or chart movement.
