 - 🧼 **Less work per update in a long chat.** Each update saved while a reply streams no longer re-examines the entire conversation, only the part being added, so the cost of an update stops growing with the length of the chat. [#28820](https://github.com/open-webui/open-webui/pull/28820)
 - 🚏 **Faster workspace model lookups.** Working out which workspace models you may edit no longer loads every model on the instance and discards most of them, which also speeds up exporting models and the file access checks that relied on it. [#28795](https://github.com/open-webui/open-webui/pull/28795)
 - 📮 **Faster handing off a streaming reply.** Passing a reply in progress between instances now writes it once rather than converting it back and forth and scanning it for characters that only matter elsewhere, which on a large non-English conversation took most of the time spent on each write. [#28833](https://github.com/open-webui/open-webui/pull/28833)
+- 🥵 **Constant load on an idle instance.** An instance sitting idle no longer works through every chat you have once a second looking for timers that are due, which on a large history kept a processor core busy doing nothing and could exhaust memory until the application was killed. [#27663](https://github.com/open-webui/open-webui/pull/27663), [#27622](https://github.com/open-webui/open-webui/issues/27622), [#27745](https://github.com/open-webui/open-webui/issues/27745)
+- 🌡 **Faster chat list and unread counts.** Opening the sidebar, and the unread markers on folders, no longer read through your whole chat history to produce a short list. [#27663](https://github.com/open-webui/open-webui/pull/27663), [#27622](https://github.com/open-webui/open-webui/issues/27622), [#27745](https://github.com/open-webui/open-webui/issues/27745)
 - 💽 **Faster saving of long chats.** A chat is now written to the database in one go rather than one message at a time, so saving a long conversation is much quicker and puts far less strain on the database, and saving one where nothing has changed writes nothing at all. [#28806](https://github.com/open-webui/open-webui/pull/28806)
 - 📦 **Faster loading of shared folders.** Folders shared with you now load in a couple of queries rather than one for each folder and each owner, so the list appears sooner for anyone with many of them. [#28804](https://github.com/open-webui/open-webui/pull/28804)
 - 🎟 **Setting up a tool server that uses OAuth.** Adding one is now easier to get right: the connection dialog can authorize the account from the dialog itself, the check button tests the sign-in details rather than reporting a connection failure that was never going to succeed without them, and it is now labelled for what it does rather than suggesting it verifies the whole connection.

 - 🗂 **Directory sync listing local accounts.** A directory service syncing accounts over SCIM now sees only the accounts that came from a directory, where it also listed and could modify accounts created with a password in Open WebUI itself. [Commit](https://github.com/open-webui/open-webui/commit/fb4f476316a2f83e4d2914d535c19b3440cbc490)
 - ↕ **Sorting a list of people.** Sorting the admin user list, or a channel's member list, now works when no search term has been entered, where the chosen order was ignored unless something was being searched for. [Commit](https://github.com/open-webui/open-webui/commit/fb4f476316a2f83e4d2914d535c19b3440cbc490)
 - 🧶 **Text dropped from a reply by a filter.** A filter that rewrites a reply as it streams, or a provider that sends something other than plain text in a chunk, no longer causes that part of the reply to vanish without explanation. [#28840](https://github.com/open-webui/open-webui/pull/28840)
+- 🏗 **Timers firing twice after a fork.** Branching a conversation that has a timer set no longer leaves the copy able to fire that timer as well. [#27663](https://github.com/open-webui/open-webui/pull/27663), [#27622](https://github.com/open-webui/open-webui/issues/27622), [#27745](https://github.com/open-webui/open-webui/issues/27745)
 - 👤 **Fallback profile pictures.** A profile picture that fails to load, such as one belonging to a deleted account, now falls back to the default avatar instead of showing clipped placeholder text beside the message. [#28270](https://github.com/open-webui/open-webui/pull/28270), [#28269](https://github.com/open-webui/open-webui/issues/28269)
 - ⏱️ **Unanswered prompts in tools.** On deployments that set "WEBSOCKET_EVENT_CALLER_TIMEOUT", a question a tool asks you that goes unanswered now reports a timeout rather than an empty reply, and waiting too long no longer risks disconnecting a tab that is still open.
