subscription in the Navionics Boating application must register with their Navionics
credentials)
- Distance circles to help finding a good anchor position
- Drop anchor by tapping on map or by position or by bearing and distance
- Can be used for anchoring with shore lines by watching the heading rather than the position
- Tracks can be saves as GPX file for later processing
- Option to set up prohibited zones which will trigger an alert when entered. These can be used indepent of the anchor state

- Fixed the mirroring/proxy status occasionally showing as stale
- NMEA position input is now more reliable: connects properly when switched on mid-session, and falls back to GPS automatically if no data arrives

- New setting: automatically prefer NMEA position while under way, with automatic GPS fallback
- New: upload the system log and recorded track directly to support from the log screen, for faster help with problems
