+## [1.6.0] - 2025-12-29
+
+### Added
+
+- **Memory System Implementation** - Complete three-tier memory architecture
+  - **Volatile Fetch Endpoints** - Scheduler-driven prefetch for ephemeral data
+    - `POST /volatile/fetch/{namespace}/{key}` - Fetch and cache external data
+    - Weather, news, and financial data providers integrated
+    - Auto-caching with namespace-specific TTLs
+  - **Unified Memory Routing** - LLM-based classification of web results
+    - Routes content to wiki (stable), volatile (ephemeral), file (documents), or prefetch (scheduled)
+    - Integrated into consolidation service post-processor
+  - **Document Recall in HybridRAG** - Paperless documents as fourth retrieval source
+    - Documents searched alongside wiki, volatile, and web in parallel
+    - New config: `enable_documents`, `document_limit`, `document_threshold`
+    - `paperless_id` field in results for document attribution
+    - `document_ms` timing in performance breakdown
+
+- **Scheduler Integration** - External scheduler service for prefetch task management
+  - `SchedulerClient` - Full REST API client for task CRUD operations
+  - `register_volatile_fetch()` convenience method for prefetch registration
+  - Consolidation service now creates scheduled tasks for prefetch-worthy content
+  - Health checks integrated into startup/shutdown lifecycle
+
+### Changed
+
+- HybridRAG now searches 4 sources in parallel (wiki, volatile, documents, web)
+- Consolidation service uses external scheduler instead of settings storage for prefetch
+
