 - 💾 **Error message persistence.** LLM errors that occur during streaming are now saved to the database even if the connection drops, so users can see what went wrong when they reconnect. [#23231](https://github.com/open-webui/open-webui/pull/23231)
 - 🚫 **Missing message completion guard.** Chat completion finalization now skips invalid requests without a message identifier, preventing unnecessary error toasts caused by rare frontend concurrency timing. [#23184](https://github.com/open-webui/open-webui/pull/23184)
+- 📉 **Pyodide prompt cache stability.** Pyodide code interpreter context is now appended to the system prompt instead of user messages, preserving stable prefix caching across turns and reducing repeated token costs in long native tool-calling chats. [#23269](https://github.com/open-webui/open-webui/issues/23269)
 - ⚙️ **Default model parameter loading.** The "DEFAULT_MODEL_PARAMS" environment variable is now parsed and applied correctly, so default generation settings are honored reliably without being ignored at startup. [#23223](https://github.com/open-webui/open-webui/pull/23223)
 - 🔧 **Web search settings save reliability.** Saving web search configuration now works without server errors, so administrators can update "WEB_FETCH_MAX_CONTENT_LENGTH" and related retrieval settings successfully from the admin interface.
