-**Status**: Proof of Concept (v0.1.0)
+A complete, lightweight vector database compiled to WebAssembly with **22 integrated WASM modules**. Runs anywhere JavaScript runs: browsers, Node.js, Deno, Bun, Cloudflare Workers, Vercel Edge Functions.
 
-RvLite is a lightweight, standalone vector database that runs entirely in WebAssembly. It provides SQL, SPARQL, and Cypher query interfaces, along with graph neural networks and self-learning capabilities.
+## What's New in v0.3.0
 
-## 🎯 Vision
+- **22 WASM modules** integrated via feature flags (up from 1 in v0.2.0)
+- **Feature-gated Cargo.toml** with individual and composite feature sets
+- **12 new extension modules**: GNN, attention, delta, learning, math, hyperbolic, nervous system, sparse inference, DAG, router, HNSW, SONA
+- **Expanded CLI** with `modules`, `delta-*`, `math-*`, `hyperbolic-*`, `dag-*`, `nervous-*`, `sparse-*`, `router-*`, and `info` commands
+- **Updated TypeScript SDK** with typed interfaces for all 22 modules
+- **Composite feature sets**: `core-plus`, `ml`, `advanced-search`, `full`
