They're the leaked ones which are usually a little rough around the edges but the general gist is correct.(They are usually patch notes from a bit in the past that haven't been updated to reflect what actually goes live)
All leaked patches in the past have been around 70-90% accurate and this one might break a record since many "fixes" have been in the pipe for a long time. There are a couple of outlandish ones which would somewhat surprise me but if you follow the info we already have the info which I reacted on seems accurate.
Here is the reddit thread if you're interested.
Looks like we can find them on this forum too http://www.mmo-champion.com/threads/...7#post21528267
