# Page History

### The Page History Panel

Keeping control over rapidly changing documentation is challenging in itself. Confluence keeps track of every change by creating a new version of the page in the [page history](https://support.atlassian.com/confluence-cloud/docs/create-edit-and-publish-a-page/#Page-versions-and-history). It is accessible from the page tree by opening the <mark style="color:green;">Page history pane</mark>l from the context menu.

### Finding *What* has Changed

After finding the [pages that have changed](/advanced-content-navigator/cloud-users-guide/show-changes-of-pages.md), the next big thing is to figure out what exactly has changed. This is where the app's <mark style="color:green;">smart page history</mark> comes into play with its <mark style="color:green;">What's changed since you last visited</mark> link.

This link intelligently determines the last page version the current user has seen and <mark style="color:green;">compares it with the current version</mark> of the page in Confluence's Page Comparison view.

The Page History Panel recognizes pages you have not yet opened at all (<mark style="color:green;">pages new to the user</mark>) and shows a link in the history to open the current version of the page.
