Plugin version not updated?

Hi,

I have come accross this great article on how to setup Enhanced Ecommerce: https://duracelltomi.com/google-tag-manager-for-wordpress/how-to-articles/how-to-setup-enhanced-ecommerce-tracking-v1-3

However, this article is for 1.3 version of your plugin and higher, and on WP plugin page latest version is 1.2 and there are no possible updates?

I have your latest update and there are no events like mentioned in EE for 1.3 article.
Can you please remove some doubts?

Thank you!
