History

Optimizely Feature Experimentation logs most actions you can perform for a project, such as creating a page, modifying a rule, and adding and removing audiences. These actions are listed in the change history, which displays 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 which changes were made, when, and by which collaborator. The detailed change history creates an activity trail that provides additional security to individuals and teams with multiple collaborators.

Project history

Each project’s change history is listed under History.

Use the filters at the top of the page to refine the changes displayed. Currently, you can filter to show changes by type, date range, and source.

For each change, you will see a Show details button. Click the button to view the specific change details, or hold alt (Windows) or option (Mac) + click to show or hide all changes.

The change history detail panel displays descriptions of each change, along with the original (before changes) in red on the left side and the updated code (after changes) in green on the right side. If you are interested, you can find out more about how this data is structured in our public API docs. To collapse the change detail view, click the Hide details button.
