The public timeline has been removed from #Holos. It is now a discovery timeline that you can tailor to your needs. You will first need to set keywords (which can be changed in settings later).
Now, with the Bloom filter, you won't even notice you're running an ActivityPub server on your device. Syncing data will be super fast.
We kept the ability to revert to legacy mode, but it won't be the default behavior in the next release.
