Fans looking forward to the upcoming World of Warcraft Classic addition coming to Blizzard's network may be excited to hear this news. This week, in a recent developer update, they announced that the build of World of Warcraft Classic would be based on the 1.12 patch. Here's a snippet from the update.

So we asked ourselves, would it still be possible to deliver an authentic classic experience if we took our modern code, with all its back-end improvements and changes, and used it to process the Patch 1.12 game data? While that might seem counterintuitive, this would inherently include classic systems like skill ranks, old quests and terrain, talents, and so on, while later features like Transmog and Achievements would effectively not exist because they were entirely absent from the data. After weeks of R&D, experimentation, and prototyping, we were confident we could deliver the classic WoW content and gameplay without sacrificing the literally millions of hours put in to back-end development over the past 13 years.
