Experience Keys in Feature Methods
Added experience_keys support in run_feature, run_features, and diagnose_feature. This addition allows developers to pass additional context, facilitating more detailed operations with features. (commit)
Type Casting in Feature Execution
Implemented type casting for run_feature and run_features. This auto-conversion of feature variables enhances flexibility when handling data types. (commit)
String Keys When Type Casting Disabled
Ensured that variable keys remain strings when type casting is not used. This standardization prevents unexpected type errors in key-value operations. (commit)
Optimized Experience Key Materialization
Improved the performance by materializing experience_keys once, ensuring the generator continuously filters without redundancy. This change resolves issues #1 and #2, enhancing efficiency. (commit)

No bug fixes were included in this release.

Anchored Bucketing Layout (Contract v12)
- Experiences now use an anchored layout for bucketing, where each variation maintains a fixed position based on its cumulative traffic allocation. Adjusting an experience's total allocation will alter each variation within its boundary, preventing shifts across all variations.
Demo Experiment-Preview Links
- Added the ability to demonstrate experiment-preview links within the demo harness for better user experience testing.

Guard Against None-ID False Match
- Added a safeguard in _find_experience_in_body to prevent false matches when encountering None IDs.
