Branch Domains

What this post added

Introduced Branch Domains, a feature allowing users to assign a custom domain to a specific Git branch for preview deployments. This ensures that the domain always points to the latest deployment on that branch, simplifying branding and sharing of preview environments. The setup involves linking a project to a Git repository and then configuring a domain to be associated with a specific branch. The Vercel REST API also supports this functionality via the 'Update a project domain' endpoint.
