 ## [Unreleased]
 
+## [0.4.1] - 2026-02-08
+
+### Fixed
+- Auto-create Qdrant collection on first use. Previously, the `zeph_conversations` collection had to be manually created using curl commands. Now, `ensure_collection()` is called automatically before all Qdrant operations (remember, recall, summarize) to initialize the collection with correct vector dimensions (896 for qwen3-embedding) and Cosine distance metric on first access, similar to SQL migrations.
+
+### Changed
+- Docker Compose: Added environment variables for semantic memory configuration (`ZEPH_MEMORY_SEMANTIC_ENABLED`, `ZEPH_MEMORY_SEMANTIC_RECALL_LIMIT`) and Qdrant URL override (`ZEPH_QDRANT_URL`) to enable full semantic memory stack via `.env` file
