v3.4.0

Tool calls will now stream in while under construction. This means that tools will render sooner and more often re-render, while partialArgs are streaming in.

New behavior (v3.4 and higher):

• 1st render: { stage: "receiving", partialArgs: {} }
• 2nd render: { stage: "receiving", partialArgs: { cities: [] } }
• 3rd render: { stage: "receiving", partialArgs: { cities: [""] } }
• 4th render: { stage: "receiving", partialArgs: { cities: ["Pa"] } }
• 5th render: { stage: "receiving", partialArgs: { cities: ["Paris"] } }
• etc.
• Then { stage: "executing", args: { cities: "Paris" } } (same as before)
• And { stage: "executed", args, result } (same as before)

Before (v3.3 and lower):

• Stage "receiving" would never happen
• 1st render would be with { stage: "executing", args: { cities: ["Paris"] } }
• 2nd render would be with { stage: "executed", args, result }

• In RoomProvider, initialPresence and initialStorage now get re-evaluated whenever the room ID (the id prop) changes.

• Add a minimal appearance to AiTool via a new variant prop.

• Improve Markdown rendering during streaming in AiChat: incomplete content is now handled gracefully so things like bold, links, or tables all render instantly without seeing partial Markdown syntax first.

• Render all messages in AiChat as Markdown, including ones from the user.

• Fix Markdown rendering of HTML tags in AiChat. (e.g. "Use the <AiChat /> component" would render as "Use the `` component")

• Improve shimmer animation visible on elements like the "Thinking…"/"Reasoning…" placeholders in AiChat.

Infrastructure

• Improved LiveList conflict resolution that will keep the conflicting element closer to its intended destination.

v3.3.4

• Fix race condition where AI tools were not always executing. This could happen when using useSendAiMessage first and then immediately opening the <AiChat /> afterwards.

• Scroll thread annotations into view when a thread in AnchoredThreads is selected, similarly to @liveblocks/react-lexical.

v3.3.1

• Fix Composer uploading attachments on drop when showAttachments is set to false.

All versions

• Fix attachment names showing URL-encoded characters. (e.g. a%20file.txt instead of a file.txt)

Infrastructure

• Fixed a bug that caused unreliable storage updates under high concurrency.
• Fixed an issue that could cause LLM responses to appear to "hang" if the token limit got exceeded during the response generation. If this now happens, the response will indicate a clear error to the user.

Dashboard

• New knowledge prompt option when configuring AI copilots, allowing you to customize when back-end knowledge is fetched.

Documentation

• More info on styling AI chat components.
• Disambiguate semantics for LiveList.delete().

v3.3.0

• Add maxVisibleComments prop to Thread to control the maximum number of comments to show. When comments are hidden, a "Show more replies" button is shown to allow users to expand the thread.

• Add onComposerSubmit callback to AiChat triggered when a new message is sent. It can also be used to customize message submission by calling useSendAiMessage yourself.

• Overrides and CSS classes for AiChat's composer have been renamed:

  • Overrides: AI_CHAT_COMPOSER_SEND → AI_COMPOSER_PLACEHOLDER
  • CSS classes: .lb-ai-chat-composer-form → .lb-ai-composer-form

• Fix: knowledge passed as a prop to AiChat no longer leaks that knowledge to other instances of AiChat that are currently mounted on screen.

• Add query option to useAiChats to filter the current user’s AI chats by metadata. Supports exact matches for string values, "contains all" for string arrays, and filtering by absence using null (e.g. { metadata: { archived: null } }).

• useSendAiMessage now accepts passing the chat ID and/or options to the function rather than the hook. This can be useful in dynamic scenarios where the chat ID might not be known when calling the hook for example.

• useCreateAiChat now accepts a chat ID as a string instead of { id: "chat-id" }.

• Allow using custom composers in FloatingComposer via the components={{ Composer }} prop.

• Add ATTACH_THREAD_COMMAND command to manually create a thread attached to the current selection.

Dashboard

• Support SAML Single Sign-On for enterprise customers.
• Allow editing first and last name in personal settings.

• Fix LiveblocksYjsProvider.getStatus() returning incorrect synchronization status for Yjs provider.

v3.2.0

• Improve AiChat's scroll behavior when sending new messages: the chat will now scroll new messages to the top and leave enough space for responses.

• Expose Markdown components in AiChat’s components prop to customize the rendering of Markdown content.

• Add blurOnSubmit prop to Composer (also available on the Composer.Form primitive and as blurComposerOnSubmit on Thread) to control whether a composer should lose focus after being submitted.

• useErrorListener now receives "LARGE_MESSAGE_ERROR" errors when the largeMessageStrategy option isn’t configured and a message couldn’t be sent because it was too large for WebSocket.

• Add tenantId to identifyUser method as an optional parameter.

Dashboard

• Fix issue with custom nodes causing an error in Tiptap/BlockNote documents views.

v3.1.4

• Fix copilot id not being passed to 'set-tool-call-result' command that is dispatched when a tool call is responded to. Previously, we were using the default copilot to generate messages from the tool call result.

v3.1.3

• Fix AiChat component not scrolling instantly to the bottom on render when messages are already loaded.

Dashboard

• Added the ability to use website crawls and sitemaps as knowledge sources for your AI copilot.

v3.1.2

• Improve URL sanitization in comments.

v3.1.1

• Adds experimental setting LiveObject.detectLargeObjects, which can be enabled globally using LiveObject.detectLargeObjects = true (default is false). With this setting enabled, calls to LiveObject.set() or LiveObject.update() will throw as soon as you add a value that would make the total size of the LiveObject exceed the platform limit of 128 kB. The benefit is that you get an early error instead of a silent failure, but the downside is that this adds significant runtime overhead if your application makes many LiveObject mutations.
• Fix: also display errors in production builds when they happen in render methods defined with defineAiTool(). Previously, these errors would only be shown during development.
• Fix an issue with the render component of tool calls not being displayed correctly when the tool call signal was read before it was registered.

Examples

• New example: AI Support Chat.

v3.1.0

• defineAiTool()() now takes an optional enabled property. When set to false, the tool will not be made available to the AI copilot for new/future chat messages, but still allow existing tool invocations to be rendered that are part of the historic chat record.

• RegisterAiTool now also takes an optional enabled prop. This is a convenience prop that can be used to override the tool’s enabled status directly in React.

• Reasoning parts in AiChat are now automatically collapsed when the reasoning is done.

• Add collapsible prop to AiTool to control whether its content can be collapsed/expanded.

• Add InboxNotification.Inspector component to help debugging custom inbox notifications.

• Add support for Redux v5.

• Fix default z-index of collaboration cursors, and make them inherit their font family instead of always using Arial.

• Add lb-lexical-cursors class to the collaboration cursors’ container.

• Improve mentions’ serialization.

• Improve mentions’ serialization.
