What this post added

Introduces the ability to disable automatic promotion of production deployments on Vercel. This allows for custom checks to be run on a production deployment before it is made live to end-users. The post details how to leverage webhooks for deployment status updates and the Vercel CLI/API to manually promote deployments after custom checks are completed. This workflow is presented as an alternative to merge queues for improving deployment safety and developer productivity.
