The following is a cumulative list of enhancements and major bug fixes in each Optimizely Performance Edge release. Because Optimizely Performance Edge releases new features and fixes as soon as they are ready, this list will update regularly.

## December

Added mutual exclusion groups to Optimizely Performance Edge. Previously, this feature was only available in Optimizely Web Experimentation and Optimizely Feature Experimentation. Now, the same feature is available in Optimizely Performance Edge. See [Mutually exclusive experiments in Optimizely Web Experimentation and Optimizely Performance Edge](docId\:xOQrC5miOld_YkbInYMFT).
