2023 Optimizely Web Experimentation release notes

  • Updated

The following is a cumulative list of enhancements and major bug fixes in each Optimizely Web Experimentation release. Because Optimizely Web Experimentation releases new features and fixes as soon as they are ready, this list will update regularly. Follow this article to receive notifications.

December 2023

New feature

  • Released automatic SRM detection.
    • Timing is everything! Every customer needs to quickly identify problems and protect their experiments from unintended traffic imbalances. Optimizely now automatically runs SRM detection tests embedded within your Stats Engine A/B experiments. When our detector finds unusual imbalances in visitor traffic to an experiment's variations, it identifies the severity and then sends out an in-product notification. You can now detect experiment problems early and without manual effort. Read the Optimizely blog post, A smoke alarm for your experiments: Introducing Optimizely’s Automatic sample ratio mismatch Detection, to learn more.

October 2023

New feature

  • Released Google Analytics 4 (GA4) Report Generation to general availability. This feature allows you to create GA4 audiences based on any experiment variation to quickly compare and contrast the performance of variations. It provides automated user and event attribution to audiences for easy report generation and eliminates the need for manual configuration in GA4 for experiment analysis.
