This was a good start, but there were issues with how the developers used to handle updates to the database data. Unlike the source code, for which Blizzard had archives for multiple branches of the game that could be worked on and developed as separate pieces, early database data was overwritten with each commensurate update. Thankfully, that problem was fixed very quickly after launch, and when we looked, we found data going back to version 1.12—and even earlier.


In this form, there is much less wasted space and spells are no longer limited to three effects. But before we can load any database data, we need to transform the old data layout into the new one. This is not limited to spells, as almost every game system (including items, creatures, player characters, spawning, AI, and more) has had its database layout altered over the years.
What add-ons can do has changed over the years and have become much more sophisticated as authors have gained years of experience and savvy. We’re not 100% on a concrete solution to what this means for WoW Classic yet, but one thing we know is that we’re not going to roll all the way back to the 1.12 add-on API. Doing so would open the way for nearly complete automation of combat decision making allowing for “bot” behavior that is counter to the core WoW gameplay experience. This is one thing we know we don’t want. On the other end of the spectrum, the modern API offers some additional functionality for creating social features that could also undermine the authentic classic experience. We’re still figuring out the details and looking for a good middle ground. We’ll be keeping a close eye on feedback from the community and add-on authors on where we should be setting those boundaries.
Beginning May 15, select WoW players will be invited to participate in a small-scale, focused closed beta test. Players will also get a chance to help put our servers and technology through their paces in a series of stress tests running from May through July—you can opt in now through Account Management and select the WoW Classic beta. Subsequent stress tests will extend the opportunity to even more players. Level caps will also be in place to ensure we’re emphasizing the “stress” in “stress test”

Classic WoW is the highly anticipated, upcoming (re) release of the original, first World of Warcraft version, known as Classic and by it's other popular ice-cream like name: Vanilla WoW. Dubbed Retail Classic, or Official Classic by the playerbase - it was finally announced by Blizzard in November 2017, after a lot of pressure from the Private Server World of Warcraft community, since the latter's shutdown of the most popular Private Server called Nostalrius which featured the first WoW version in two separate PvP and PvE servers.
