If it is not, when is IPP 7.0 slated to be released for production use?
>6.1 license is not appropriate for version 7.0. we are planning to release IPP v.7.0 in the end of November.
This also depends on the expiring date of your IPP 6.1 license. After you register your license file, you can get one year support and software update. If you 6.1 license is not expired before the IPP 7.0 release, you still can use the license file. If it is expired, you need to renew it or purchase a new one.
