This release expands NIP-15 marketplace support, preserves NIP-99 service listings. ## Highlights ### Channels To Stalls And Shops The biggest change in v0.2.0 is the move away from channels as a discovery model. What changed: - removed channels screens, models, viewmodels, factories, and channel-specific helpers
More…
- introduced stalls and shop-oriented browsing flows - added structured stall and product models - added stall cards, product cards, and a dedicated stall detail flow What this means: - discovery is now centered on marketplace activity instead of channel participation - sellers can present a shop or stall identity with products underneath it - buyers can move from a stall to its products more naturally ## Nostr Protocol Support ### NIP-15 Marketplace Expansion Hisa now leans much more heavily into NIP-15 for marketplace behavior. Included in this release: - support for stalls using kind `30017` - support for products using kind `30018` - stronger marketplace event parsing with improved JSON-content handling - improved stall and product publishing through `NostrStallUtils` - explicit stall detail routing with `stallId`, `ownerPubkey`, and `eventId` Result: - stalls and products are handled as first-class marketplace data - product loading is tied more cleanly to a specific stall - the marketplace model is more structured and easier to grow ### NIP-99 Service Listings Still Supported NIP-99 remains an important part of Hisa for service listings. Included in this release: - centralized NIP-99 feed loading through a shared repository-backed flow - shop ownership views filtered against the shared services feed - better metadata hydration for service publishers Result: - Hisa supports both shop-style marketplace discovery and service listings - the app keeps compatibility with its existing service-listing model while expanding marketplace support ### NIP-25 Reactions In Messaging Messaging now supports NIP-25 reactions. Included in this release: - support for kind `7` reactions - reaction-aware rendering in message bubbles and conversation previews Result: - conversations feel more expressive - lightweight feedback is easier without sending a full DM - Feb 28, 2026 0.1.9Release description: Short summary: Hisa v0.1.9 improves messaging reliability and UX, ships a NIP‑44 V2 crypto module, adds TabLoading for consistent tab skeletons, and prevents self-messaging on listings. Highlights NIP‑44 V2: complete crypto refactor with HKDF‑SHA256, modular API (nip44.encrypt() / nip44.decrypt()). Messaging reliability: DM buffering during initial load, coordinated EOSE + processing finalization, gift‑wrap (NIP‑59) hardening and dedup. Relay & subscriptions: improved EOSE handling, event dedup LRU cache, per‑channel load finalization. UI/UX: new TabLoadingPlaceholder + rememberTabLoadingVisibility() hook; bottom navigation redesign; My Shop and self‑messaging prevention. External signer & storage: safer external signer flows (launcher checks, fewer prompts), enhanced secure storage.
