\## \[0.2.0] - September 11th, 2019
This release of the SDK introduces Feature Management capabilities for running both Feature Rollouts as well as Feature Tests using Optimizely Feature Management.

\### New Features
\- Introduces feature variable getters via \`GetFeatureVariable\*\` for parameterizing your feature tests.
\- Introduces the \`Track\` API call for sending conversion events to Optimizely.
\- The \`IsFeatureEnabled\` API will now send impression events if there is a feature test attached to the feature being accessed.

\### Breaking Changes
\- Vendored packages have been removed in favor of declaring dependencies and their versions using \`go.mod\`.
