• This change adds a new nested extension (jacdac folder)
  and does not modify the existing extension. Your existing lessons, tutorials and blocks are not impacted by this change.
• No hardware modification is required for existing accessories, this feature
  is backward compatible. However, it requires a micro:bit V2 to run.

The benefits for the users and you will be:

• Digital twins Jacdac surfaces the hardware state directly into the MakeCode editor
• Standardized blocks and lessons the programming will be done through
  Jacdac blocks maintained by the Microsoft team
