How to renew the support?

1.5.6 is the latest version.

1.2.71 is old so definitely upgrade.

You can change here: https://generatepress.com/category/development/

The link takes me to Generate Press 2.01 is that even a newer version of GP Premium?

That's the latest version of the GeneratePress THEME.

GP Premium is a plugin.

Hey Tom I was unaware a lifetime license to you is 20 years. You said before Oct. 2016 and I clearly am... :(

Easy Digital Downloads didn't have a lifetime option when you originally purchased, so we set it to 20 years.

I just set it to lifetime now :)

Thanks Tom, you're the best!
