+
+### 🐛 Bug Fixes
+
+- **#224 — Chat→Responses translation creates invalid reasoning IDs** — Removed synthetic reasoning item generation in `openaiToOpenAIResponsesRequest()`. The translator was creating reasoning items with IDs like `reasoning_15`, but OpenAI's Responses API requires server-generated `rs_*` IDs, causing `400 Invalid Request` errors from Responses-compatible upstreams. Fix: omit reasoning items entirely during translation
+- **CI: duplicate OmniRoute.exe in release workflow** — Removed redundant explicit `release-assets/OmniRoute.exe` entry that caused `softprops/action-gh-release` to fail with 404 on duplicate upload. PR #222 by @benzntech
+
+### ✨ New Features
+
+- **Electron Auto-Update** — Added auto-update functionality to the desktop app using `electron-updater`. Includes IPC handlers for check/download/install, "Check for Updates" in system tray menu, desktop notification when update is ready, and silent startup check (3s delay). PR #221 by @benzntech
+
+### 📦 Dependencies
+
+- Bump `actions/cache` from 4 to 5 (#225)
+- Bump `actions/download-artifact` from 4 to 8 (#226)
+- Bump `docker/login-action` from 3 to 4 (#227)
+- Bump `actions/upload-artifact` from 4 to 7 (#228)
+- Bump `docker/build-push-action` from 6 to 7 (#229)
+- Bump `express-rate-limit` from 8.2.1 to 8.3.0 (#230)
