Scopes and contextual values for environment variables are now generally available on Netlify, offering new features such as scope limits and deploy context-specific variable settings. These changes aim to improve the management of environment variables, allowing developers to better control data access and reduce potential issues with Lambda functions. The new experience is production-ready and can be used across all sites today, with existing teams able to opt-in on a site-by-site basis or automatically migrate to the new experience in early 2023.
