NOTE:
Please note the following if you have enabled automatic logging in the background (indicated by the blue frame in the app):
Continued use of GPS in the background can drastically reduce battery life. In our experience, however, a full day of sailing can be done with it, nevertheless don't forget the 12V charging cable ;-)

New:
- Wind arrows now step up in 5-knot increments instead of Beaufort scales.

Fixed:
- If the location field was empty, the app now shows light text in Dark Mode.
- You can no longer enter more than one decimal point when logging engine hours.
- In the PDF, text in the last column no longer shifts when you set a long label to wrap over two lines.
- Stability improvements in the NMEA overview.
- An incorrect value for GPS accuracy via NMEA in the data sources is fixed.
- The first water and fuel tanks are no longer pre-filled in the first logbook entry if they do not exist.
