The Netlify team has introduced a new feature in their UI that allows developers to manage scopes and contextual values for environment variables, providing more advanced use cases such as limiting environment variables to specific scopes or changing values based on deploy context. This release is available in beta through Netlify Labs and enables users to set context-based values directly from the app UI, with features including filtering by key and reviewing individual values. The new experience is designed to improve security and flexibility for developer teams, but there are some known limitations during the beta phase, such as limited support for branch deploy contexts and Netlify CLI functionality.
