The following new supported markdown types for rich text when using Block Kit in your apps are being rolled out:

• syntax-highlighted code blocks (language-specific)
• tables
• task lists
• dividers
• variable-sized headers

Check out our rich text block and markdown block reference for more details!

Display your apps' and agents' actions with three new Block Kit components:

• The task_card block displays a single task.
• The url source element displays clickable URL references within a task card.
• The plan block displays multiple of those tasks together in a unified view.

How tasks are displayed is set with a new parameter in the text-streaming API methods: task_display_mode. Use this to choose whether your app's tasks appear individually or in a comprehensive plan.

Then update the task cards and plan via the new chunks parameter. The parameter also supports plain markdown.
