    Update Log

    The barometer will now work again in iOS 17.4 and later. Because of privacy changes in iOS 17.4 barometric data are bow tied to Motion and Fitness. In order to make it work you have to enable Fitnesstracking in your devices privacy settings under "Motion and Fitness". After restarting Anchor Sentry you have to go there again and enable Anchor Sentry, which will now have its own entry there, to access the data.

    - Fixed a color problem with the titlebar in iOS 15+.
    - Using the bearing/distance part of the anchoring dialog, once you start entering values manually in the bearing field, the compass updates will be suspended.
    - Other ships at anchor (on the server) no longer trigger a proximity alert if the last position update from the ship is older than 2 hours. It is then assumed that that ship left without properly raising anchor within the app.
