This will roll out to the official app stores and vger.app soon(tm), once I’m confident there are no major regressions. If you prefer not to switch to beta builds, just hang tight.
Please note that Piefed support is EXPERIMENTAL! There are still many things that don't work quite right, which I'm hoping to improve over the coming weeks.
The basics including scrolling home/all/local, viewing posts, blocking, commenting and voting should work well. However there are some known issues:
Can't sign up for a Piefed account in-app, only log in with an existing one
Subscribed communities list is empty (should be fixed soon!)
Inbox tab doesn't load
Comment search doesn't work
Profile upvoted/downvoted doesn't load
No moderation tools
Mark as read doesn't persist
Creating/editing posts is currently untested
...probably a bunch of other stuff too, please let me know below!
Behind the scenes, this interoperability is made possible thanks to aeharding/threadiverse, a new library I am working on to normalize various threadiverse-software APIs. It's open source so any project use it, but it's under heavy development right now. What's cool about this is in the future, adding support for mbin, or whatever else is possible!
Again, feel free to try it out and let me know if there are any more issues to be documented and fixed.
