I just gave it a shot during lunch on Android and the app is missing the OSM data I added to my neighborhood, so I am assuming it's still using their old data and that they'll kick over to the OSM data as part of an update.
That's part of the puzzle, but it's (AFAIK) mostly for code review and bug tracking. I'm very much interested in the build tooling & automated testing (& probably also deployment) pieces.
This stuff is still in beta and not generally useful, but we have Harbormaster (Build/CI), Drydock (software resource management) and Releeph (release management) in the pipeline.
This page shows all 4 platform apps. What I am missing?
