A couple of asset store item sellers of assets I have have decided to create entirely separate branches of their asset for Unity 2018. And I have a gut feeling that this will also be the case for the Unity post processing stack. And one of them outright stated they will no longer support the asset for Unity versions greater than 2017.4. Is this going to be the new-norm for major Unity releases? Is anyone else seeing this trend with assets you're using? IF this is the case then we are locked-in, whereas before, upgrading to Unity 2017 was not that big of a deal. But I think upgrading from 2017 to 2018 might be out of the question for most people that are far along.
