Do not worry, you already have the latest eazyBI version on Cloud. Cloud is updated automatically and has the most recent features and bug fixes 
You may retrieve some Xray specific custom fields, like Test Environment, Test Type. Or import scripted custom field TestRunStatus (see this Community post for more details on how to import the field: TestRunStatus Custom field Xray in EazyBI)
Howevere, those workarounds won’t provide you with metrics on test executions and execution results (PASS, FAIL, WIP, etc.)
If you are willing to participate in testing the new eazyBI integration with Xray Cloud, you can write to support@eazyBI.com and apply.
