Vercel has improved its project management features by making it easier to edit the Git connection of a project, which can be done using the new "Git Integration" setting in the Project Settings. The company has also refined the "Git Integrations" page for personal accounts and teams, providing a clear overview of the status of the Git connection and how to edit it. Additionally, Vercel now allows users to manage existing connections to Git providers with equal ease as importing a new repository, making deployment processes more streamlined.
