December

• Released event properties, which let you attach additional information to an event to all customers. See Custom events in Web Experimentation
• Revamped the Extensions feature – Extensions is now Experience Templates (beta), which lets you streamline campaign and experiment creation and reduce code duplication. You can use the pre-built templates provided by Optimizely to quickly create a campaign or experiment with little to no development or build your own. See Get started with experience templates for information.
• Released the following UX delights:
  • You can open the desktop app with Optimizely's updated logo from the web app and log in directly from the browser.
  • You can automatically upload custom code into a Web Experimentation project directly from your GitHub repository through an out-of-the-box GitHub Action integration.
  • Optimizely informs users in the UI if they have insufficient permissions to enable or edit an integration.
  • Optimizely informs users if they input an invalid character in the list attribute name in real time.
  • You can reference the snippet versions from the UI to help ensure you deploy the most updated snippet.

October

Released event properties to open beta. See Custom events.

September

• Released Optimizely Reporting for Experimentation, providing you with dashboards and reports that show key metrics such as experiment velocity, conclusive rate, win rate, and uplift.
• Updated the API Name text field in the New Custom Event page to automatically populate with the Name formatted in lowercase, replacing any non-alphanumeric characters with underscores. See Create a custom event.
• Released Integrate Google Analytics 4 (GA4) Audiences for general availability. This lets you target experiments based on segments in GA4 without custom development, unlocking new targeting capabilities within Web Experimentation, such as demographics-based audience creation and predictive audience identification for potential purchases within a specified timeframe.
• Released contextual multi-armed bandits to beta for personalization campaigns. Contextual multi-armed bandits (CMABs) help you deliver the most personalized variation to each user by dynamically re-allocating traffic based on the primary metric and user attributes. Contact your Customer Success Manager to learn more.

August

Released event properties to beta. Event properties let you filter a created event in Optimizely’s UI based on additional information you have attached to it. When you send events, you can add information about the product or action performed to create a more specific metric when using the event in the experiment results. Contact your Customer Success Manager or sign up for the beta on Optimizely.com. See Custom events.

July

• Renamed the following Optimizely REST API endpoints to clarify they archive the entities instead of deleting them:
  • Archive an experiment.
  • Archive an in-page event.
  • Archive a page.
  • Archive a campaign.
  • Archive an attribute.
• Added a Concluded status for experiments to stop serving variations. You can mark whether the outcome was Positive, Negative, or Inconclusive, then give a Description of the findings. See Manage experiments for information.

June

• Upgraded the Chrome Extension from Manifest V2 to Manifest V3 with Google phasing out Manifest V2 extensions. This upgrade improves security, privacy, and extension performance while maintaining all existing functionality.
