version property
The version string the storefront is showing, such as 1.1.6.
Compare it against the version you are asking about. versionReleasedDate is the date of this version, so a caller asking "when did 1.1.7 go out" while the storefront still shows 1.1.6 has been handed 1.1.6's date — and this field is the only thing that says so.
Implementation
final String? version;
