What's Changed

  • Fixed Bucketing Regression - From v4.0.0 SDK started to support v2 hashing but the evalFeature had a forced a check using v1 Hash, ignoring the rule's actual configuration.
  • Fix FNV1a to accept full 16-bit values for cross-platform consistency preventing users from falling into different buckets on different devices.
  • Update test scenarios spec - for sticky bucketing - minExperimentBucketVersion - Merge pull request #134 from growthbook/fix/forced-v1-check (dc7bf03)
