 - 🗂️ **Model selector layout.** The model selector now behaves more predictably as a custom popup, and the completions playground uses a simpler model picker for easier selection. [Commit](https://github.com/open-webui/open-webui/commit/c40ea7f29d34fa9535cdf9ffe599f4429ff3f455)
 - 🎨 **Theme updates.** Other windows can now update the app theme directly, keeping the interface in sync when theme changes are triggered externally. [Commit](https://github.com/open-webui/open-webui/commit/9f1b279e88bd22dfff4d2531209536dea6a2f65e)
 - 🚀 **Async performance and responsiveness improvements.** The core backend database and request paths now run asynchronously across the application, massively improving responsiveness and performance under concurrent load and reducing request blocking during heavy activity. [Commit](https://github.com/open-webui/open-webui/commit/27169124f220e5cea21c88601c731c3749496ab0), [Commit](https://github.com/open-webui/open-webui/commit/8936721414a17832852a90f3ee592af5a8b7232d)
+- 🚀 **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)
 - 🏃 **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)
