# Version control
You can easily monitor all the changes people have made to your content using to the **Version history** side panel.
### Version history
In the Version history of a space, you can see a list of all the actions that changed the content within it. These include:
* When someone made [live edits](/docs/collaboration/live-edits.md) to the space.
* When someone merged a [change request](/docs/collaboration/change-requests.md).
* When someone performed a [Git Sync](/docs/getting-started/git-sync.md) operation.
### View historical versions of content
To view past versions of your content and see the changes that were made, click the **Version history** button in the [space header](/docs/resources/gitbook-ui.md#space-header), or open the **Actions menu** next to the space or change request title and choose **Version history**.
Click on any item in the list to see how your content looked at the point this change was made. This is very similar to how you view [change requests](/docs/collaboration/change-requests.md).
### Show changes
When you are viewing an old version of your content, you can choose to highlight the differences between the old and current content — similar to [diff view in a change request](/docs/collaboration/change-requests.md#diff-mode).
To enable or disable this, use the **Show changes** toggle at the bottom of the **Version history** side panel.
With show changes enabled, content that has changed will be highlighted by an icon on the left of its content block.
### Viewing historical published versions
If you're investigating the version history of a published space, you can also view previews of what the previous versions looked like in the published context (i.e. what the end user would see).
You can do this by:
{% stepper %}
{% step %}
From the version history side panel, select the revision
{% endstep %}
{% step %}
Copy the ID at the end of the URL
{% endstep %}
{% step %}
Add it at the end of your published docs URL as `/~/revisions/`
{% endstep %}
{% endstepper %}
### Roll back to a previous version
Rolling back allows you to revert a space’s content to the way it was at a previous point in time. This is helpful if you’ve accidentally made a breaking change or deleted content and need to quickly get back to a previous version of the space.
To roll back to a previous version of your space, hover over the version in the side panel, click the **Actions button** and select **Rollback**.
