## 3.8.1

August 2nd, 2021

### Bug Fixes:

Fixed duplicate experiment key issue with multiple feature flags. While trying to get variation from the \`variationKeyMap\`, it was unable to find because the latest \`experimentKey\` was overriding the previous one. (\[#282]\([https://github.com/optimizely/ruby-sdk/pull/282](https://github.com/optimizely/ruby-sdk/pull/282)))
