+# 0.2.44
+
+## Features
+
+- **K/J** keys now snap the viewport to the top of previous or next assistant responses.
+- **J/K** (vim mode) now navigate between assistant responses in scrollback.
+- **sequenceDiagram** mermaid blocks now render as Unicode lifeline diagrams instead of source fallback.
+
+## Bug Fixes
+
+- **Interjecting** while editing a queued prompt no longer strands the composer or blocks the queue.
+- **Mid-turn interjections** now appear as separate user messages instead of being appended to tool results.
+- **Project MCP config** touches no longer trigger repeated reload storms.
+
+## Performance
+
+- **Inference requests** recover faster from silent engine stalls instead of waiting the full idle timeout.
