Many, many improvements to Relay and RelayPool performance (reduced atomic operations and switched to async concurrency), add NostrSigner trait, better methods and struct names (fetch_events instead of get_events_of, sync instead of reconcile, NostrConnect instead of Nip46Signer and so on), add LocalRelay and allow to easily serve it as hidden onion service with the embedded tor client, allow to keep track of negentropy sync progress, almost halved the weight of JavaScript SDK bindings (from ~6.3MB to ~3.6MB), some fixes and many more!
Note for Python, Kotlin, Swift and JavaScript devs: unfortunately I can't mark things as deprecated in bindings, so this release have many breaking changes, sorry :(
Note for devs who are using nostr-protocol (Python), org.rust-nostr:nostr (Kotlin), nostr-swift (Swift) or @rust-nostr/nostr (JavaScript) libraries: these packages are now deprecated. Only the nostr-sdk library will be released, which include everything that was in those libraries.
