Hi, does Confluence put versions on changed pages? How does that work?
Sure, that is a standard thing in Confluence. You choose "Page History" in the top menu of your Confluence page. Then you will see the versions and be able to pick and compare any two.
Here's the Atlassian documentation where you find how to do all of this:https://confluence.atlassian.com/doc/page-history-and-page-comparison-views-139379.html
