# Versions

version is an object. Contains source, status and change time fields for versioned metrics.

When a metric is versioned, the database retains the history of series value changes for the same timestamp along with version_source and version_status.

Name	Description
versioned	Boolean. Returns version status, source, time/date if metric is versioned.
versionFilter	Expression to filter value history (versions) by version value, status, source or time, for example: value > 0, version_status = 'Deleted' or version_source LIKE '*user*'. To filter by version time, use the date() function, for example, version_time > date('2015-08-11T16:00:00Z') or version_time > date('current_day'). The date() function accepts End Time syntax.
