Of course we do not "silently remove features" from the list. This would be even illegal. When you purchase software, you're entering a contract with the seller, and the feature list is a part of that contract.

It is true that engine plugins worked with 7.82 free, but this was not intentional. It was a bug. For obvious reasons, we don't list bugs of this kind in the bug list.

I can understand that someone is annoyed when he developed a plugin and suddenly can't use it anymore. I can not change the feature list because that's not my sole decision. But I can offer this: All people who owned the free version 7.82, and have written an engine plugin for it and can now not use it anymore, can contact the support. They will receive a complimentary Extra Edition.
