+            ## What's new
+
+            ### Search accuracy improvements
+            - **Weighted ranking**: filename matches rank above path matches, which rank above body matches (bm25 10/5/1)
+            - **Path search**: search by folder/path segments finds documents in nested directories
+            - **Prefix matching**: partial queries match as you type (e.g. "hel" finds "hello")
+            - **Highlighted snippets**: search results show `<mark>` highlighted body excerpts
+            - **Exact filename boost**: typing an exact filename always surfaces it first
+            - **Auto-relevance sort**: active search uses relevance ranking; empty browse uses recency
+
+            ### Other
+            - Safe FTS5 schema migration (old databases upgrade automatically)
+            - Documentation updated: OCR, watcher, `.doc` support, ranking behavior
+            - 22 new search accuracy tests (unit + integration + e2e)
