\### New Features
\* Introduce Numeric Metrics - This allows you to include a floating point value that is used to track numeric values in your experiments.
\`\`\`
var eventTags = new EventTags()
\{
\{ "value", 10.00 },
};

OptimizelyClient.Track(eventKey, userId, attributes, eventTags);
\`\`\`

\* Introduce Forced Variation - This allows you to force users into variations programmatically in real time for QA purposes without requiring datafile downloads from the network.
\`\`\`
var result = OptimizelyClient.setForcedVariation(experimentKey, userId, forcedVariationKey);
\`\`\`

\* Upgrade to use new \[event API]\([https://developers.optimizely.com/x/events/api/index.html](https://developers.optimizely.com/x/events/api/index.html)).
