New site in version 2 or 3

I think that 3.0 is days alway. All breaking changes are already completed.
It possible that some change until its released which can make a problem if you start with the current snap of 3.0,  but I think that the current 3 dev is even more stable then 2.2 ..  

So you can start using it and just keep an eye over the framework for Final release.

Thanks, what about the new features in CI3 compared to CI2, also what is getting deprecated/removed? Is there any good place/table/article I can see those?
