Changelog

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.

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.

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

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.
