+# Changelog
+
+All notable changes to Library Desk will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [1.1.0] - 2025-12-11
+
+### Added
+
+- **Smart Page Creation Endpoint** (`POST /wiki/pages/smart-create`)
+  - Combines HybridRAG research with LLM content generation
+  - Searches existing wiki, knowledge graph, and web for topic context
+  - Uses WikiPageWriter to synthesize findings into structured wiki content
+  - Auto-generates page path from topic if not provided
+  - Returns research summary with source counts
+
+- **Bidirectional Entity Linking**
+  - New shared utility (`entity_linking_utils.py`) for reusable entity linking
+  - Forward links: Links entities mentioned in new pages to existing entity pages
+  - Backward links: Updates existing pages that mention the new entity
+  - Runs automatically in background after smart page creation
+
+- **Version Management**
+  - Added `pyproject.toml` with project metadata and version
+  - Version is now read from `pyproject.toml` (single source of truth)
+  - Health check endpoint returns current version
+  - FastAPI docs show current version
+
+### Changed
+
+- Updated `config.py` to read version from `pyproject.toml`
+- Updated `main.py` to use centralized version
+
+## [1.0.0] - 2025-12-10
+
+### Added
+
+- Initial release extracted from portainer-core
+- Wiki page management (`/wiki/pages` CRUD endpoints)
+- HybridRAG search (`/query/hybrid`) with vector, graph, and web search
+- Knowledge graph operations (`/graph/*`)
+- Vector search operations (`/vector/*`)
+- Knowledge consolidation from search results (`/consolidate/knowledge`)
+- Entity linking and extraction
+- Wiki.js change listener for auto-processing user edits
+- Multi-tenant architecture with user namespace isolation
