Nostr Compass #12 is out. The Marmot Development Kit shipped v0.6.0 as its first public release with encrypted media, multi-language bindings, and over 200 merged PRs. Nostrability published outbox model benchmarks testing 14 relay selection algorithms across 15 clients, finding that Thompson Sampling with dead relay filtering pushes event recall above 90%. Wisp, a new Android client, went from first alpha to beta in eight days with 19 releases, Tor support, and NIP-55 signing. This issue also covers NIP-91 (AND filters) merging, Vector v0.3.1's 15x performance gains, and a Five Years of Nostr Februaries retrospective tracing the protocol from three relays to mesh networking. nostr:naddr1qqgrwdnxvyukxdnpv3jnjcehxdnrvq3qwav4fae3gyfy3xj298kxj2mj8phavz7vavps34przq02j7w902qqxpqqqp65wem3n2q
