3. Integration with CI/CD: Changesets can be integrated into continuous integration and deployment workflows, automating the release process and reducing manual effort.
4. Customizable: Users can customize how changesets are processed and how versioning is handled, allowing for flexibility based on project needs.
5. Collaborative: It encourages collaboration among team members by providing a structured way to document changes and communicate about releases.
