#Amethyst v1.00.0: Full Outbox

This version completes our migration to the outbox model, where the app dynamically manages the relay list used to pull posts from your follows' own relay lists. By default, the app will connect to relays that aren't in your lists through our embedded Tor. Normal usage will connect to hundreds of relays. Many of them will fail, and that's ok. Nostr has baked-in redundancy; these failures won't affect your experience.

New relay lists were added to the UI to help you manage how the app works. Specifically, you can now block relays and add trusted relays. Trusted relays will connect outside of Tor, which is faster, but allows those relays to see your IP. You should only add relays there if you trust the relay operator. Proxy relays (like filter.nostr.wine) can be added to the proxy list. After that, the app will only use those relays to download the content for your feeds, disabling the outbox model. DMs and other non-outbox functionality will still use their own relays. Broadcasting relays can be added to push your events out there. Every new event from the app will be sent to all broadcasting relays. Finally, the new Indexer list allows you to choose which relays to use to find users, like purplepages.es.

For users of our Quartz library, we have finished all of the work to change the library's mindset from a fixed list to a dynamic pool of relays. Now, each NIP has its own dedicated folder and defines its own tags and caching structures. This expansion allows us to add diverse functionalities such as relay clients, relay servers, event builders, Nostr filter builders, caching systems, deletion and event hint indexers, helper functions, and more—all specifically tailored to each individual NIP. This modular approach creates the space to develop each NIP independently and integrate them into Amethyst as distinct modules, while still sharing Amethyst's main relay and cache engine when necessary. We expect fewer breaking changes as we move forward with it. At some point, Quartz will move to its own repository and be converted to a Kotlin Multiplatform project for each NIP/module. This will allow us to build demo/testing applications for each NIP in the same repo.
