Open WebUI 发布: v0.11.2

来源摘要

### Added - 🖼️ **Richer previews for terminal files.** Word documents and slide decks produced in the terminal are now previewed as the finished document rather than an approximation, and every document preview gains a page strip down the side with numbered thumbnails you can click to jump straight to a page, and the notice warning that a preview might differ from the download is gone now that it does not.

[#29146](https://github.com/open-webui/open-webui/pull/29146) - 🏎️ **Lighter model list refreshes.** On deployments running several workers, a refresh that finds the model list unchanged no longer has every worker rewrite the whole list to the shared cache, cutting the work and the traffic each refresh costs. [#29264](https://github.com/open-webui/open-webui/pull/29264) - 🧵 **Smoother busy websocket servers.** Large Redis-backed websocket deployments now spend far less time sweeping old sessions, reading their own session data back from Redis, and checking every outgoing websocket message for file attachments Open WebUI does not send, so channel posts, collaboration updates, heartbeats, and live cha
