 ## Next Steps
 
-### Immediate (Phase 3 Continuation)
+### Immediate (Phase 3 Completion)
 
-1. **Test Windows Executable Functionality**
+1. ✅ **Windows Release Workflow** - COMPLETE
+   - Build executable with checksum
+   - Create release on Forgejo
+   - Upload assets (exe + checksum)
+   - Tested with v0.0.2 release
+
+2. ⏳ **macOS Release Workflow** - Script ready, untested
+   - Requires macOS machine to test
+   - Script `create_release.sh` ready to use
+   - Same workflow as Windows version
+
+3. ⏳ **Push Release Tags** (Optional but recommended)
    ```bash
-   # Run the application
-   .\build\dist\windows\WebDropBridge.exe
+   git tag -a v0.0.2 -m "Release 0.0.2"
+   git push upstream v0.0.2
+   ```
 
-   # Verify:
-   # - Main window opens
-   # - Web view loads
+### Phase 4.1: Auto-Update System (Next Phase)
+
+The release infrastructure is now ready for Phase 4.1 implementation:
+
+1. **UpdateManager Design**
+   - Query Forgejo Releases API: `GET /api/v1/repos/HIM-public/webdrop-bridge/releases/latest`
+   - Parse release assets (exe + checksum)
+   - Download latest executable
+   - Verify SHA256 checksum
+   - Replace current executable
+   - Restart application
+
+2. **Example Integration Code**
+   ```python
+   from src.webdrop_bridge.core.update_manager import UpdateManager
+   
+   manager = UpdateManager(
+       repo_url="https://git.him-tools.de/HIM-public/webdrop-bridge",
+       current_version="0.0.2"
+   )
+   
+   if manager.update_available():
+       manager.download_and_install()
+       manager.restart_app()
+   ```
+
+3. **Forgejo API Endpoint**
+   ```
+   GET https://git.him-tools.de/api/v1/repos/HIM-public/webdrop-bridge/releases/latest
+   
+   Response:
+   {
+       "id": 1,
+       "tag_name": "v0.0.2",
+       "name": "Release 0.0.2",
+       "body": "...",
+       "assets": [
+           {
+               "id": 1,
+               "name": "WebDropBridge.exe",
+               "browser_download_url": "https://git.him-tools.de/..."
+           },
+           {
+               "id": 2,
+               "name": "WebDropBridge.exe.sha256",
+               "browser_download_url": "https://git.him-tools.de/..."
