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.
• Released the ability to sign up for email notifications when Optimizely Experimentation detects a sample ratio mismatch in your running experiments. See Enable email notifications in Optimizely Experimentation.

May

• Updated the Optimizely Personalization UI by renaming Experiments to Optimizations and surfacing Personalization Campaigns, making it easier to create and manage campaigns.
• Renamed and released Advanced Audience Targeting to Real-Time Segments for Web Experimentation. This lets you use Optimizely Data Platform (ODP) real-time segments to build your Web Experimentation audiences.
• Released the ability to use cross-project events to track events from your Optimizely Feature Experimentation projects in your Optimizely Web Experimentation project. See Cross-project events.

April

• Released targeting dynamic selectors for general availability. This lets you use the Visual Editor to target specific attributes for your dynamic website or single-page application (SPA) more reliably and with a lower configuration time.
• Released the ability to link a hypothesis in Experiment Collaboration with an experiment in Optimizely Web Experimentation.

March

• Updated the Test URL(s) to save after leaving the page settings. This lets you revisit the settings to see the page conditions and the effects of adjustments to those conditions.
• Added an ID column for Audiences and Extensions to retrieve the information faster.
• Updated the HTML box to be collapsible in the Visual Editor.

February

• Released targeting dynamic selectors to beta.

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.
