Thank you for contacting support. We do not share API versions older than one year. We always recommend our customers use the latest version of all Aspose APIs. Furthermore, newer versions always come up with more features, fixes and improvements.
Second, you can evaluate our latest APIs with full features support. You need to get a temporary license for 30 days and try the latest version at your end. You can download a latest version of Aspose.Total from the download area here: https://releases.aspose.com/
