v1.4.0

• Introduce WidgetTemplate for building widgets from .widget files instead of hand-crafting widget models.
• Add ClientEffectEvent for triggering client-side behavior in ChatKit.js.
• Add overridable ChatKitServer.handle_stream_cancelled and get_stream_options methods to support configurable response cancellation behavior.
• Add SDKHiddenContextItem with default ThreadItemConverter handling to store ChatKit-added hidden context in threads.

Breaking:

• Widget and action classes remain usable but are marked deprecated in favor of using WidgetTemplate
• jinja2 is a required dependency for widget template rendering.
• A stop button shows by default during streaming so users can cancel mid-response; integrations can override ChatKitServer.get_stream_options to change this.

v1.3.1

• Add optional group field to UserMessageTagContent
• Update default ThreadItemConverter to handle simple HiddenContextItem conversions
• Add ThreadItemUpdatedEvent and update ThreadItemUpdated to be a type alias for the former for backwards compatibility
• Add BasicRoot widget type to allow server-side building of entity preview widgets

v1.3.0

• Fix type for Checkbox defaultChecked

v1.2.0

v1.1.1

v1.1.0

• Fix thread persistence (store now receives ThreadMetadata correctly).
• Drop Python 3.11-only features. Now works cleanly on Python 3.10.
• Allow the payload field on Action to be undefined by defaulting to None

Breaking:

• Restrict the icon field on CustomSummary, CustomTask, and EntitySource types to IconName (previously str).
• Update all ThreadItemConverter methods to be asynchronous.

v1.0.2

• Loosen the type of chatkit.agents.ClientToolCall.arguments from dict[str, str] to dict[str, Any]. ClientToolCall.arguments can be any JSON serializable object.

v1.0.1

• EntitySource includes an optional data dict that will be piped through onClick and onRequestPreview client-side callbacks
