I've been working on my hobby project, nostr-java, a java library for creating, signing, publishing nostr events to relays.
We've added support for nip44, and done some refactoring on the nostr-java-api module, with the goal to make it even easier and simpler to use. The updates have been pushed onto the develop branch.
I've been thinking this morning about adding a caching layer, to speed up requests and reduce the load on relays. This will probably be the next major feature.
With nip44 in place, I can now focus on my nip46 implementation, another separate hobby project of mine, a remote signing tool inspired by nsecbunker.
