Ten languages — The interface is now translated into English, Spanish, French, German, Brazilian Portuguese, Japanese, Korean, Simplified Chinese, Traditional Chinese, and Italian. Translated template library — Every template category, name, and description is translated, so browsing for the right starting point works in your language too. Translated Pro workspace — Generate, Ask, and Fix, the local LLM setup, and Diagram Cloud sign-in and sync all read in your language, including their status and error messages. Per-app language picker — Settings ▸ Appearance ▸ Language lets you run PrivyMermaid Pro in a language of its own, independently of the rest of your device. Choose System to follow your device setting. Sensible language matching — Regional variants land where you would expect: Traditional Chinese for Taiwan, Hong Kong, and Macau, and Brazilian Portuguese for other Portuguese regions. Your diagrams stay yours — Diagram source is never translated, and existing diagrams, projects, and cloud templates keep working unchanged when you switch languages.

- **LM Studio support** — Choose Ollama or LM Studio as your local LLM engine. Set a custom endpoint for each and pick your model from Settings. - **First-launch LLM setup** — New Pro users see a short onboarding screen: configure your LLM (Configure) or skip and set it up later (Skip). If you skip, the Pro panel shows a clear “not configured” message with a link to Settings. - **Streamlined Settings** — LLM (Pro) section with Engine picker (Ollama / LM Studio), endpoint fields, model list, and “Refresh models.” Prompts are no longer in Settings. Open Source Licenses and About are in Settings under Legal and at the bottom. - **Stability** — License viewer resource path fixed so the in-app Open Source Licenses page loads correctly.
