I saw a YouTube video that went through all the retcons from Warcraft I: Orcs & Humans through the end of BfA. That seemed to be the time the video was created. One thing it pointed out was all the retcons in the Chronicles.
Funny thing is, one of the big complaints about Shadowlands was that the entire expansion was a retcon but most of what it reconed were things that the Chronicles had retconed earlier.
The anti SL crowd swears that the Chronicle retcons are canon but what was established in the game, before or after, is not.
