## Breaking Changes & Deprecations
- - 💥 **Replies stop breaking mid-chat.** A conversation no longer fails in the browser and stops showing the assistant reply until you reload, and chats already saved in that state display and can be edited again.

## New Features
- 🖼️ **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.

- ⚡ **Less overhead on every message.** Deployments without pipelines configured, which is the default, no longer pay setup work for them on each chat message and background task. #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
- 🧵 **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 chat updates put less load on busy servers. #28835, #28180
- 🧰 **A new request filter step.** Filter authors can now use `request` to adjust the payload right before each model call, including follow-up calls after tool use, while existing `inlet`, `stream`, and `outlet` filters keep working as before. Commit, Commit
- 🤏 **More room in file previews on touch screens.** File previews on phones and tablets no longer show zoom buttons that sit over an already small preview, leaving pinch to zoom to do the job. #29176, #29152

## Bug Fixes
- 🛡️ **Security Advisory**: This release includes security and access-control fixes. We recommend updating production deployments at your earliest convenience. Not all security fixes in this version may be enumerated in the fixed section. Some may be withheld for a short time to give administrators time to upgrade. Advisories
- 💥 **Replies stop breaking mid-chat.** A conversation no longer fails in the browser and stops showing the assistant reply until you reload, and chats already saved in that state display and can be edited again. #29250, #29244
- ⌨️ **Preview shortcuts stay in the preview.** Arrow keys now page a document or slide preview only while that preview has focus, instead of paging it from anywhere on the page and taking the arrow keys away from whatever you were typing in. Commit, Commit
- 🧊 **Streaming no longer stalls on reasoning models.** A reply from a reasoning model now streams through to the end instead of showing its first few words and then freezing until generation finishes. #29053, #29035
- 💭 **Thinking stays in Thoughts.** After a model uses a tool, its reasoning for the next step now appears in the collapsed Thoughts section instead of being written into the reply as ordinary text. #29052, #29040
- 🧠 **Large tool calls stream faster through Anthropic-compatible clients.** When a streamed tool call sends a large block of arguments, Open WebUI now waits until that block can actually be complete before checking it, instead of doing the same expensive check again on every tiny piece. #28858
