When changes are made to the CSF, but the version number is not bumped, a changelog should be published and assessors and subscribers should be alerted. Currently subscribers often create spreadsheets of requirements for internal use as they prepare for their next assessment.

Sometimes, for a variety of reasons, the assessment object may get refreshed or even deleted and recreated. If a change has occurred to the CSF that didn't bump the version number, the subscriber will end up with an assessment object that doesn't 100% align with their preparation efforts. This is usually not discovered until well into the assessment and causes customer frustration with the framework - sometimes even called a moving target.
