New Features and Improvements

  • New Anchored Bucketing Layout

    • The bucketing layout is now selected by experience.version. Experiences with version > 11 use the new anchored layout, offering improved distribution logic over the old packed cumulative walk approach. See commit.

  • Anchored Layout Reference Implementation

    • The JavaScript SDK now includes a reference implementation for the anchored layout as defined in contract v12. See commit.

  • Full Stack v12 Enhancements

    • Introduced features for safer traffic ramp-up, variation preview, and experiment exclusion, enhancing the flexibility and safety of experiment management. See commit.

  • Mutual-Exclusion Audience Rule

    • Added a new audience rule for mutual exclusion based on bucketed_into_experience_key, allowing for more precise targeting and exclusion logic. See commit.

  • Zero-Trace Location Events

    • Implemented zero-trace location events and encoded config-fetch parameters to enhance the privacy and security of API interactions. See commit.

  • Force Preview Target in runExperiences()

    • The SDK now supports forcing the preview target in runExperiences() to achieve parity with run-all functionality, ensuring consistent behavior during previews. See commit.
