      Be sure to include the following areas if relevant:
      If this is a major capability update, what has changed?
          For example: This change introduces Python 5 that runs without the Global Interpreter Lock and is fully multithreaded.
      If this is a new functionality, what capabilities does it bring?
          For example: This change allows package upgrades to be performed automatically and rolled-back at will.
      Does this improve some specific package or set of packages?
          For example: This change modifies a package to use a different language stack that reduces install size by removing dependencies.
      Does this improve specific Spins or Editions?
          For example: This change modifies the default install of Fedora Workstation to be more in line with the base install of Fedora Server.
      Does this make the distribution more efficient?
          For example: This change replaces thousands of individual %post scriptlets in packages with one script that runs at the end.
      Is this an improvement to maintainer processes?
          For example: Gating Fedora packages on automatic QA tests will make rawhide more stable and allow changes to be implemented more smoothly.
      Is this an improvement targeted as specific contributors?
          For example: Ensuring that a minimal set of tools required for contribution to Fedora are installed by default eases the onboarding of new contributors.
 
    When a Change has multiple benefits, it's better to list them all.
