+## 🔥 MAJOR UPDATES: What's New in v0.51, v0.49 & v0.48
+
+### 🎯 **v0.51: Revolutionary Developer Experience** 
+
+**Problem-focused approach that gets you productive in seconds!**
+
+- ✅ **Problem-Solution Narrative** - Immediately understand why Brainy exists
+- ✅ **8-Line Quickstart** - Three search types in one simple demo  
+- ✅ **Streamlined Documentation** - Focus on what matters most
+- ✅ **Clear Positioning** - The only true Vector + Graph database
+
+### 🎯 **v0.49: Filter Discovery & Performance Improvements**
+
+**Discover available filters and scale to millions of items!**
+
+```javascript
+// Discover what filters are available - O(1) field lookup
+const categories = await brainy.getFilterValues('category')
+// Returns: ['electronics', 'books', 'clothing', ...]
+
+const fields = await brainy.getFilterFields()  // O(1) operation
+// Returns: ['category', 'price', 'brand', 'rating', ...]
+```
+
+- ✅ **Filter Discovery API**: O(1) field discovery for instant filter UI generation
+- ✅ **Improved Performance**: Removed deprecated methods, now uses pagination everywhere
+- ✅ **Better Scalability**: Hybrid indexing with O(1) field access scales to millions
+- ✅ **Smart Caching**: LRU cache for frequently accessed filters
+- ✅ **Zero Configuration**: Everything auto-optimizes based on usage patterns
+
+### 🚀 **v0.48: MongoDB-Style Metadata Filtering**
+
+**Powerful querying with familiar syntax - filter DURING search for maximum performance!**
+
+```javascript
+const results = await brainy.search("wireless headphones", 10, {
+  metadata: {
+    category: { $in: ["electronics", "audio"] },
+    price: { $lte: 200 },
+    rating: { $gte: 4.0 },
+    brand: { $ne: "Generic" }
+  }
+})
+```
+
+- ✅ **15+ MongoDB Operators**: `$gt`, `$in`, `$regex`, `$and`, `$or`, `$includes`, etc.
+- ✅ **Automatic Indexing**: Zero configuration, maximum performance
+- ✅ **Nested Fields**: Use dot notation for complex objects
+- ✅ **100% Backward Compatible**: Your existing code works unchanged
+
+### ⚡ **v0.46: Transformers.js Migration**
+
+**Replaced TensorFlow.js for better performance and true offline operation!**
+
+- ✅ **95% Smaller Package**: 643 kB vs 12.5 MB
+- ✅ **84% Smaller Models**: 87 MB vs 525 MB models
+- ✅ **True Offline**: Zero network calls after initial download
+- ✅ **5x Fewer Dependencies**: Clean tree, no peer dependency issues
+- ✅ **Same API**: Drop-in replacement, existing code works unchanged
