Two poins:
The standard doesnt ask to keep the old version.
It needs control of changes.
Dont you think is it sufficient to show the description of the change described in the document? And also signatures of reviewers and approvers?
Other point, I worked in an engineering company that, avoided the manage of obsolet documents, because when engineers used by mistake obsolet documents, caused very costly errors, e.g. instead of using drawings rel 6, used rel 4.
