You can view the change history for your projects and identify changes that might have caused problems with your experiments.
Optimizely Experimentation logs most actions you can perform for a project, like creating a page, modifying a variation, and adding and removing audiences. These actions are listed in the change history, which shows the record of user activity for each of your projects.
If an experiment starts to behave strangely or stops working correctly, you can troubleshoot by checking the change history to see the changes that were made, when, and by which collaborator. The change history creates an activity trail that provides additional security to individuals and teams with multiple collaborators.
Each project’s history is listed under History:
Open the Show details drop-down list to see changes.
Use the drop-down lists at the top of the page to filter the History displayed by the Type of change or select Date to view the history in a time frame.

In general, the change history detail panel displays the original (before changes) in red on the left side and the updated code (after changes) in green on the right side.
The following sections show change detail examples to demonstrate the information listed for changes to different features.
Audience Conditions
For each audience condition, you will see type and value keys. Check the values for these keys for the specific changes made to the audience.
Extensions
Change history displays changes to Apply JS, Reset JS, HTML, and CSS in the extension builder.
Variation changes made with the Visual Editor
For changes made to elements using the Visual Editor, a full code representation of the Visual Editor change is visible, so you will look for the property or attribute that was actually modified. In this example, font-weight was set to "bold."
In the following example, the value for the html key was changed from "Gear for Fall" to "Gear for the cooler months."
Variation changes made with the Code Editor
Change history displays changes to CSS and JavaScript code made with the code editor.
