🔗 Naming Experimental Features

One of the features I shipped in assistant-ui was file attachments. To give users early access to this feature, I added the experimental_attachments field to our messages object:

type UserMessage = {
  // ...other fields
  experimental_attachments: Attachment[]; // new!
}

A few months passed and I was ready to mark the feature as stable, but renaming experimental_attachments to attachments was a breaking change. The API didn't change, yet users had to update their code.
