What’s New in Version 2.3.1

This version improves offline behaviour and fixes a few bugs.

  • Improved Extra Features subscription handling during offline use.
  • Map view: Make it possible to dismiss and hide error messages, such as the error message about no network. It got a bit silly in the long term when using the app offline for a longer while. Tap the error message and select “Dismiss” to make it go away!
  • Replaced alert popup views with a new pretty popup in many places to remove a deprecated UI component.
  • Fixed a bug where the app would crash when receiving a packet with a short destination callsign from a TNC. The Device Identification code got a bit upset about it.
  • Messaging: Show a correct “not logged in” error in case of “bad callsign” if not logged in. An initial login is required to create and synchronise callsigns and profiles; after that messaging will still work offline as before.
  • Tons of updates in translations: German, Icelandic, Japanese, Portuguese, Dutch, Simplified Chinese. Thank you to everyone who helped!

This will be the last version which supports iOS 11 – in case you have one of the two devices out there with iOS 11, please look into upgrading. Thanks!
