This is because of a patch a while back that released a patreon version on accident. Instead of reverting the changes they just keep releasing from that point and use it as another way to test. It doesn't affect gameplay really, but if people do run into it, it acts as testing. It is kind of made this way not to upset patrons(I think).

That doesn't make any sense? I know about the accidental release but I still don't see how that would be a reason to keep the changelog a full month behind the version of that's available.
The difference between the Itch.io and Patreon versions is mainly the Story mode. They're only a few patches ahead of free players. (Currently 3.21.2) So I don't see how as Itch.io users and not having access to the story mode we could do any extra "testing" that hasn't already been done?
we are a larger group of people. More people=more testing. Also the changelog shows things that are ready. Some things have not been ready for a long time that were in the game, such as the orc ass eat(it was in the script for the longest time but never really adjusted and made ready until recently). There is always things that may not be ready, but what is, or the official release of new implementations, are ready now.
What is the problem with having extra content?
