Historical patch changes

Early API changes were communicated on the official World of Warcraft forums. Blizzard employee slouken interacted with addon developers such as Community MVP Iriel who consolidated many changes into summary posts on the forums. Although the original forums have been taken down, blue post tracking websites like BlueTracker archived substantial parts of these threads. Some of Iriel's posts were also transcribed to early forms of Wowpedia.
