For a character's history, there should be a link provided to their Earth-1/38/73 counterpart, followed by another header describing any changes between the two.

Ex: John Diggle

Post-Crisis Changes
Following the destruction of the multiverse, the Paragons and Oliver Queen created a new Multiverse, thus, some changes are denoted in Diggle's history. In this new Earth-Prime, Diggle now has both a daughter, Sara Diggle and a son, John Diggle, Jr.

Following this, continue on with the post-Crisis history. This is actually very convenient, as it provides more cleanliness, as many character pages, such as Diggle's, have become so cluttered and backed up due to their extensive history in the Arrowverse. I may even suggest doing this for the Paragons, as technically the original counterparts merged with the Earth-Prime versions of these characters, while maintaining memories from their previous counterparts.
