Not all models have all the functionality available at the release, which may break some functions. Also, the interface for using them may change
My friend, I have never asked my supporters to buy licenses. I provide a product and give the opportunity to support me to those who need this product and wants to support its development. Releasing add-ons for XenForo has never been directly profitable, and I have never made any promises that I would regularly release updates for them. I work on my products when my resources allow me to, so I ask you to be understanding. If you have personal wishes to speed up the development of a particular product, you can also contact me and we will do it for a separate fee within a time frame that suits you 🙂
