Postman has introduced new features to enhance collaboration between API producers and consumers by allowing forks and pull requests for environments, similar to collections. This update facilitates the creation of reference environments through forking, which simplifies the process of sending requests by enabling users to work with copies of environments without altering the original. Users can now keep their environments synchronized with the original through pull requests, ensuring they incorporate any updates seamlessly. These features also help prevent accidental changes by allowing work in separate contexts, with the option to merge changes once finalized. Additionally, collaboration is enhanced through pull requests, enabling team members to comment, review, and request changes before merging. Overall, these updates aim to streamline the process of API development and consumption while maintaining the integrity and currency of environments.
