 - 🌊 **Middleware cancellation reliability.** Long-running requests now complete more reliably by preventing middleware-level cancellations from interrupting in-flight database and embedding work, reducing unexpected failures and noisy error logs when connections close early. [#23709](https://github.com/open-webui/open-webui/pull/23709)
 - 🚦 **Async vector search responsiveness.** File processing, memory updates, and knowledge retrieval no longer block the server event loop during vector database operations, so other chats and requests stay responsive while indexing or search is running. [#23706](https://github.com/open-webui/open-webui/pull/23706)
 - 🗒️ **Notes chat llama.cpp compatibility.** Notes AI chat no longer sends empty assistant prefill messages that can conflict with reasoning-enabled llama.cpp responses, preventing immediate 400 errors in Notes conversations. [Commit](https://github.com/open-webui/open-webui/commit/fd93bd3414a1725219e14561bc5640b62f9fd4a1), [#23703](https://github.com/open-webui/open-webui/issues/23703#issuecomment-4243907629)
+- 🧭 **Background task scoping for new chats.** Chat title and auto-tag generation now run only for the first message of a new conversation and only once in multi-model responses, preventing duplicate or incorrectly triggered background tasks in follow-up flows. [Commit](https://github.com/open-webui/open-webui/commit/f102060a6d85db4acd3d0bf5c25e976f36cd5533..a4ed16999eec9a654a37c2bb4c15ba5ecd1fa3b7)
 - 📚 **Channel document context retention.** Channel conversations now preserve and load the correct stored message history so model responses can use uploaded and retrieved document context more reliably. [#23686](https://github.com/open-webui/open-webui/issues/23686), [Commit](https://github.com/open-webui/open-webui/commit/cf4218e688def6f11d195aeda6665ae5b5376b67), [Commit](https://github.com/open-webui/open-webui/commit/18fe17127a7175579506e7456d3e5aba201371e6)
 - ⏳ **Interrupted response recovery.** Assistant placeholder messages now start as incomplete and recover more safely after interrupted generations, preventing silent empty replies after refreshes or dropped requests. [#23176](https://github.com/open-webui/open-webui/issues/23176), [Commit](https://github.com/open-webui/open-webui/commit/c8ef7b028931263e8773cb60a7111d80d9572d26), [Commit](https://github.com/open-webui/open-webui/commit/cf4218e688def6f11d195aeda6665ae5b5376b67)
 - 🧰 **Large tool result rendering.** Tool call details now display large result payloads reliably in chat instead of intermittently showing empty output for bigger tool responses.
