Alright, Shijimah. Time to exercise some critical thinking. I know you were probably brought up as a Christian in America and taught not to question anything, but do your best anyway:
There's nothing in the release notes. This means that nothing has been changed. That should be fairly obvious, and we should be able to assume this.
There have been many rioters talking about the jungle changes. This means that there are going to be changes.
There have been many other people talking about the changes. This means that it's pretty well known in the community.
So what do we have? Confirmation of jungle changes, but no jungle changes yet. So what can we conclude? In the future, there will be changes to the jungle - more specifically, to the best of my knowledge, once the preseason is over, we'll be getting the changes.
