Policies are not static, they often change based on business processes or products. Whenever a policy undergoes a major change, it is important to save versions of that policy along with its date. Just like software, policy too has to be versioned, tracked and compared.
SubPage provides support for revisions in policy editor. It automatically creates a policy version whenever a policy is modified along with its new updated date and it is published.
Also these revisions can be deleted, compared with each other and shown to end-users. of the changes made between policy revisions.
For legal compliance, it is necessary to maintain and show an archive of all changes made to your business policies.
