Changelog

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.

Website

• New blog post: What’s new in Liveblocks: June 2025.

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.

v3.0.0

Liveblocks 3.0 is our third major release, focusing on our newest product, AI Copilots. We’ve used this as an opportunity to tidy up some of our existing APIs, ensuring consistency throughout our offering.

For full upgrade instructions and codemods, see the 3.0 upgrade guide.

• TypeScript 5.0 is now the minimum supported version.

• Remove deprecated APIs, see the deprecated section in the upgrade guide to learn more.

• Introduce hooks and APIs for AI Copilots: useAiChats, useAiChat, useDeleteAiChat,useSendAiMessage, RegisterAiTool, RegisterAiKnowledge, etc.

• Rename UPDATE_USER_NOTIFICATION_SETTINGS_ERROR to UPDATE_NOTIFICATION_SETTINGS_ERROR when using useNotificationSettings or useUpdateNotificationSettings.

• Introduce pre-built components for AI Copilots: AiChat, AiTool, etc.

• The onMentionClick prop on Thread and Comment now receives a MentionData object instead of a userId string.

• The Mention component on the Comment.Body and Composer.Editor primitives now receives a mention prop instead of a userId one.

• The MentionSuggestions component on the Composer.Editor primitive now receives a mentions prop instead of a userIds one, and the selectedUserId prop has been renamed to selectedMentionId.

• Rename LiveblocksUIConfig to LiveblocksUiConfig for consistency with other Liveblocks APIs.

• Remove deprecated htmlBody/reactBody properties from prepareThreadNotificationEmailAsHtml/prepareThreadNotificationEmailAsReact, use body instead.

  • The id property now refers to the mention’s ID, as in the user ID used for the mention

• The element prop received by the Mention component in prepareTextMentionNotificationEmailAsReact now contains an id property instead of userId, and a new kind property to indicate the mention’s kind.

We are introducing thread subscriptions to add more granularity to thread notifications, allowing users to subscribe to threads without participating or unsubscribing from specific ones.

None of these changes are breaking but you can learn more about them, their rationale, and how to automatically apply them with a codemod in our Upgrade Guide for 2.24.

• Rename getRoomNotificationSettings, updateRoomNotificationSettings, and deleteRoomNotificationSettings to getRoomSubscriptionSettings, updateRoomSubscriptionSettings, and deleteRoomSubscriptionSettings.

• Add Room.subscribeToThread and Room.unsubscribeFromThread methods.

• Methods which return threads and their associated inbox notifications now also return the thread’s associated subscriptions.

• Add support for textMentions in room subscription settings.

• Rename Room.getNotificationSettings and Room.updateNotificationSettings to Room.getSubscriptionSettings and Room.updateSubscriptionSettings.
