Ver. 0.2.0 (July 2025)

This release has been focused on developing a working Android app ("Celeste").
The app is approaching beta level and will soon be available to a test team.

The underlying navigation toolkit has been unchanged since the last release.

This release added a simple app which can be used as starting point for further app development (Android or iOS).

Ver. 0.1 (May 2025)

This is a major tag/release featuring the following:
