What's New in v0.4.16 Bug Fixes

• Electron Window Close: Override draw.io iframe beforeunload so the window can be closed after editing a diagram on macOS/Windows (fixes #815) (#840)
• Kimi Reasoning Models: Use createDeepSeek for the Kimi provider so reasoning_content round-trips correctly in multi-turn conversations (fixes #824) (#825)
