For a given page with a version history, I want a permalink URL that will compare a specific historical version of the page to the current version, even as the current version is updated.
This article explains how to get a link between an arbitrary version and the version that's current *at that time*: https://confluence.atlassian.com/doc/page-history-and-page-comparison-views-139379.html#PageHistoryandPageComparisonViews-Viewanolderversion
But this link is only valid at the time it is generated. It creates something like this: .../pages/diffpagesbyversion.action?pageId=12345&originalVersion=90&revisedVersion=100
Once the "current version" is no longer 100, but something like 105, this link won't work.
I want an evergreen link that will always compare some historical baseline to whatever the latest-and-greatest is. Basically some syntax that replaces "100" in the example above with "whatever the current version number is". Is this possible?
