A running list of breaking changes to be contained within the v3 release.

New Features

Rename package (last step of release)

• Finalize all v3 work, code freeze v3/beta/etc branch
• Rename repo to ibm-ai-applications
• Rename package scope to @carbon/ibm-ai-applications in package.json

• Consider not re-exporting Carbon
