We've done months of work on overhauling the Messaging app. It has been done in incremental portions with code review for each. It often goes back and forth several times before it gets merged. Why not look at the quite open development and code review process on GitHub?

Every release of GrapheneOS and GrapheneOS apps goes through internal testing followed by public Alpha channel testing and then public Beta channel testing before reaching the Stable channel. No update goes to Stable without internal, Alpha and Beta channel testing phases.

We've been heavily testing our Messaging overhaul as we've been doing it and we've been making a lot more tests than we used to. It's already in quite good shape and is ready for Alpha channel testing. That's what we're referring to.

What? The Messages overhaul has been going on in the background for months. They announced it near the end of the port rather than the start. What is wrong with that? It has nothing to do with AI.

You can check github and see this development has been going on for awhile.
