Netlify has introduced a feature that allows users to configure their build plugins based on specific deploy contexts, such as production, deploy previews, or branch deploys. This means that users can now define which plugins run in certain contexts and even apply context-specific settings to those plugins. To achieve this, users need to edit their `netlify.toml` file, where they can specify different build configurations for different contexts. The new feature aims to save time and reduce noise by allowing users to customize the behavior of their plugins based on the specific deployment scenario.
