Updates the version of the plug-in that was stored when the plug-in was added to the clip.

## Declaration

func updateVersion(atCreation newVersion: UInt32) -> Bool
```

## Parameters

- `newVersion`: The new version number.

## Mentioned in

Versioning and obsoleting old plug-ins

## Return Value

Return Value If the update was successful, this method returns YES; otherwise, NO.

## Discussion

Discussion No information about previous backward compatibility is stored, and the plug-in is treated by the host app as if it were created with the specified version number. Updating fails if the specified number is lower than the already-saved version number.
