 - 💨 **No filter work on installs without filters.** A completed message on an install with no filter functions and no pipeline filters, which is the default, no longer rebuilds the whole conversation and ships it to the browser as an event nothing acts on. [Commit](https://github.com/open-webui/open-webui/commit/28f2965934f5b6fba0e0c38a15b2af6ee790819f)
 - 📂 **Opening a file in a knowledge base.** A file listed in a knowledge base can now be opened and read straight from that list, where the name was shown but nothing happened when it was clicked. [Commit](https://github.com/open-webui/open-webui/commit/20f35d157bc7d535091ce6a90b517c23d26486c0)
 - 🧵 **Cheaper saving of a reply as it streams.** The resume snapshot taken on every piece of a streamed reply no longer rebuilds the whole answer each time, so the cost of a save stops growing with the length of the reply. [#28821](https://github.com/open-webui/open-webui/pull/28821)
+- 📀 **Less repeated work setting up built-in tools.** Every chat request no longer rebuilds a fresh copy of each built-in tool's definition from scratch, which was paid once per tool on every message. [#28860](https://github.com/open-webui/open-webui/pull/28860)
 - ♿ **Improved UI accessibility.** A closed sidebar is no longer reachable by keyboard or announced by screen readers, the tool call blocks in a response can now be expanded with the keyboard, the buttons that normally appear on hover, such as message actions, file removal, and chat menus, now appear when you reach them with the keyboard as well, whatever you have tabbed to is marked with a clear outline throughout the application, and the rows in the integrations menu now tell a screen reader whether each tool or feature is switched on.
