 - ⚡ **Drawer performance and memory optimization.** Drawer interactions now stay smoother over long sessions by removing stale keyboard listeners on teardown, which reduces memory growth and avoids accumulated event handling overhead. [#23724](https://github.com/open-webui/open-webui/pull/23724#issuecomment-4245840810)
 - 🚀 **Chat history memory culling.** Long conversations now stay much more responsive by rendering a smaller message window and unloading off-screen messages with spacer-based virtualization, significantly reducing memory pressure and UI freezing on heavy chats and mobile devices. [#23067](https://github.com/open-webui/open-webui/issues/23067), [Commit](https://github.com/open-webui/open-webui/commit/026903399be73ac4b6c226647110e5662d043a50), [Commit](https://github.com/open-webui/open-webui/commit/9dccd29c94875e6f0ac373c5802cb183296e47ff)
 - 🧵 **Async file and knowledge processing performance.** File processing, knowledge reindexing, and channel message helper paths now consistently await async operations, preventing skipped processing steps and improving reliability and performance of indexing and tool responses. [Commit](https://github.com/open-webui/open-webui/commit/de27a121511a31606f250ba4033490797216a0eb)
+- 🚀 **Persistent chat payload efficiency.** Persisted chats now use server-side history loading instead of repeatedly resending full message payloads, improving multimodal performance and reducing stale-history overwrite risk across devices. [#19064](https://github.com/open-webui/open-webui/issues/19064), [Commit](https://github.com/open-webui/open-webui/commit/18fe17127a7175579506e7456d3e5aba201371e6), [Commit](https://github.com/open-webui/open-webui/commit/cf4218e688def6f11d195aeda6665ae5b5376b67)
 - 🧵 **Non-blocking file storage operations.** Uploading, reading, transcribing, and deleting files now offloads storage I/O to background threads, keeping the application responsive during file-heavy workflows. [Commit](https://github.com/open-webui/open-webui/commit/4866bec0f238198a721c952fe18dd04ba643be33)
 - 🏃 **Faster automation list loading.** The automations page now loads more smoothly by batching latest-run lookups and avoiding duplicate initial fetches. [Commit](https://github.com/open-webui/open-webui/commit/09f6d7ba57d2aaad83ad0d29d005feb7157776a1)
 - 🏎️ **Streaming response performance.** Streaming responses now process each output line in a single step instead of two separate yields, reducing async overhead and improving responsiveness during long-running generations. [#23266](https://github.com/open-webui/open-webui/pull/23266)

 - 🗒️ **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)
 - 📚 **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. [#18743](https://github.com/open-webui/open-webui/issues/18743), [Commit](https://github.com/open-webui/open-webui/commit/45e49d33e51f7720c00b564215484aff9b48b20c)
 - 🧼 **Null-byte document sanitization.** PDF and other document ingests now sanitize null bytes and invalid surrogate characters before pgvector writes, preventing PostgreSQL upload failures and allowing affected files to index successfully.
