Vercel has released several updates in June 2020, including changes to deployment features, security, and user interface improvements. The creation of new ZEIT Now 1.0 deployments is prohibited until August 7th, 2020, and the x-vercel-trace header has been replaced with x-vercel-id. Deployments will now retain cache directories between builds again, and a 404.html file present in the output of a deployment's build will be considered when rendering a 404 error. Sending a Range header to a deployment will no longer bypass the Edge Network cache. Additionally, vercel dev will start up faster for projects with serverless functions written in Node.js, and running vercel without an internet connection will now render a helpful error. Other changes include improved logging, domain management, and integration with GitHub and Bitbucket.
