Today, AWS announces 4 new user roles available in Amazon CodeCatalyst: space Power user, space Limited access, project Reviewer, and project Read only. The Power user role has permissions to create projects and add AWS accounts. The space Limited access role is the default role for space members and has permissions to list space projects. The project Reviewer role has permission to use CodeCatalyst issues and approve pull requests, but it does not have source code or workflow change permissions. The Read only role gives read only access to project resources, with no create, update or delete permissions.
