v2.0.0

2.0.0 (2026-07-24)

⚠ BREAKING CHANGES

• Experiences on bucketing contract v12 (experience version above 11) bucket visitors with the anchored layout, where each variation holds a fixed position derived from its cumulative traffic allocation. Changing an experience's total allocation now grows or shrinks each variation at its own boundary instead of shifting every variation range, so visitor-to-variation assignments under contract v12 differ from the earlier packed layout for the same configuration.

Features

• anchored bucketing layout (bucketing contract v12) (df5a8c7)
• demo: demonstrate experiment-preview links in the demo harness (0d4dd38)

Bug Fixes

• preview: guard _find_experience_in_body against None-id false match (508a5d7)
