Cline Desktop v0.0.44 Brings Interactive Mermaid Diagrams and Improved Connectivity
Cline Desktop's latest update introduces interactive Mermaid diagram rendering, more robust mid-chat session reconnection, expanded compatibility with local/self-hosted models, and multiple fixes related to model handling and Windows MCP server startup.
What changed?
Cline Desktop v0.0.44 introduces inline, interactive Mermaid diagram rendering in chat, allowing users to copy, download, view fullscreen, and pan or zoom diagrams. Diagram links now use a confirmation dialog that clearly shows the destination. The release improves chat reliability by automatically attempting to reconnect sessions for up to one minute after a dropped connection, delivering any queued messages if reconnection succeeds. Local and self-hosted model providers without API keys, such as LM Studio and Ollama, now function again after previously failing due to API key errors. MCP servers started on Windows using 'npx' or 'uvx' load reliably, with the startup time limit increased from 3 to 10 seconds. The update also fixes issues with Claude via custom Anthropic endpoints and Kimi K3's reasoning level constraints, updates the model catalog, and changes default models for several providers.
Why does it matter to an everyday developer?
Developers using Cline Desktop will notice richer real-time collaboration and documentation workflows due to interactive Mermaid diagrams within chat. The improved connection handling reduces chat session interruptions, especially when using the Cline Hub, which previously resulted in message loss or manual resends after any drop. Developers running local or self-hosted LLMs (for privacy, cost, or speed) can now use popular backends again without failed sessions caused by missing API keys. The fix for MCP server startup eliminates issues for Windows users running locally managed compute. These improvements collectively boost reliability, workflow fluidity, and expand support for hybrid development and testing across different AI model sources.
What can the developer do now?
Upgrade to Cline Desktop v0.0.44 to use interactive Mermaid diagrams in chats, benefiting from advanced diagram interaction features. If your workflow includes local or self-hosted AI models, you can resume seamless session initiation with LM Studio, Ollama, vLLM, and similar endpoints. Windows users deploying MCP servers should see more reliable initialization with the increased timeout. When using chat-based workflows, expect fewer disruptions due to temporary connectivity drops—the application now handles auto-reconnects. Check the updated model catalog, as default providers may have changed, and the free/available model list now adds Solar Mini 4 and removes others. If integrating with specific models like Claude through custom Anthropic URLs or Kimi K3, compatibility issues should be resolved.
