### 3.1 Automatic removal of non current objects versions

A non-current object version is a version which is not the latest for a given object. It is possible to set up an automatic removal of non-current versions when a version becomes older than a given number of days.

e.g., To scan objects stored under `user-uploads/` prefix and remove versions older than one year.

```

    "Rules": [
        {

		return true
	}
	if !chkNumVersions(fivs.Versions) {
		t.Fatalf("Expected all versions to have the same NumVersions")
	}

	sort.Slice(versions, func(i, j int) bool {
		if versions[i].IsLatest {
			return true
		}
		if versions[j].IsLatest {
			return false
		}
		return versions[i].ModTime.After(versions[j].ModTime)
	})

	for i, fi := range fivs.Versions {
		if fi.VersionID != versions[i].VersionID {

			}
		case "VersionID":
			z.VersionID, err = dc.ReadString()
