 - ⚡ **Faster model overview.** The admin model overview now loads its feedback history and tags through batched queries, so it opens noticeably faster on instances with many chats. [Commit](https://github.com/open-webui/open-webui/commit/40c09167cd6de1c853a5dd03c88b4fdcb279dfe1)
 - 🏎️ **Lighter channel profile previews.** Profile previews in channels now load a person's details only when you hover to open one, rather than fetching them for every message up front. [Commit](https://github.com/open-webui/open-webui/commit/4f69c33de0e9a8fde4f16d0b2f1ed8aac8741772)
 - ↩️ **Reset permissions to defaults.** The group and default permission dialogs now include a button to restore all permissions back to their built-in defaults in one step. [#25931](https://github.com/open-webui/open-webui/pull/25931)

 - 👯 **Side-by-side chat with the same model.** Running two panes with the same model no longer leaves one pane stuck waiting or showing the other pane's reply after a reload, since each pane's messages are now tracked separately. [Commit](https://github.com/open-webui/open-webui/commit/56ae99e96a845289b5787d2dd26a3d828f2295e7), [#25982](https://github.com/open-webui/open-webui/issues/25982)
 - 💾 **Model edits no longer lost when changing access.** Adjusting a model's access no longer auto-saves on its own and discards your other unsaved changes to that model. [#26004](https://github.com/open-webui/open-webui/pull/26004)
 - 🔧 **Parallel tool calls over the Anthropic-compatible API.** External Anthropic-compatible clients calling Open WebUI's messages endpoint now receive tool calls reliably when a model issues several at once or returns them in its final message.

+- 🗃️ **Prompt caching preserved over the Anthropic-compatible API.** Requests through the Anthropic-compatible API now keep their prompt-caching markers instead of having them stripped, so clients that rely on caching work as intended.

 - 🔎 **Steadier search boxes across admin and workspace.** Search fields for users, knowledge, prompts, tools, and similar lists now run only as you type and reset to the first page correctly, instead of occasionally re-searching on their own.

 - 🗂️ **Deleting nested folders checks chats correctly.** Deleting a folder that contains subfolders now accounts for the chats inside those subfolders when applying the delete-permission check, instead of only the top-level folder's chats.
