will patch notes be up on the official release or at early access?

B-but it's not a patch. I mean, are they posting notes for a whole expansion? Really? o.O

It is a patch. Some things/systems are changing in ARR with the release of the expansion. And there is also a substantial patch that has to occur for all users to make sure that everyone stays compatible i.e. people that don't buy Heavensward are going to still need the files for new jobs, new gear, new abilities, etc. so their game doesn't crash whenever they run into someone with the expansion.

An extansion is just a patch that you have to buy if you want to access most of what it offers.

From Friday, June 19, 2015 at 2:00 a.m. (PDT)

*There will be maintenance before early access starts.
This maintenance will update the data for the expansion, A Realm Reborn content, and implement other fixes.

patch notes were alwasy first on Lodestone before Yoshida have read them from the Lodestone live.
