Final answer:
The ability to track relationships and changes to configuration objects is an important feature of an SCM repository.
Step-by-step explanation:
The ability to track relationships and changes to configuration objects is indeed one of the most important features of an SCM (Software Configuration Management) repository. SCM repositories are used to manage the versions and configurations of software projects, providing a centralized location for storing and tracking changes to configuration files, source code, and other development artifacts. By utilizing version control systems such as Git or Subversion, developers can easily track changes made to configuration objects over time and collaborate with others on the project.
