We’ve been hard at work on World of Warcraft®: Warlords of Draenor™, and today we’ve entered the Alpha phase of our expansion testing. As part of this, we’ll begin using public servers to host the data, which means you may begin seeing some datamined information show up in the usual places.
One of our goals for this very early stage of the Alpha is to test out some new technology in the wild with employees and friends and family, including a new file format called CASC (more on that below). As such, the expansion content available during this first phase will be quite limited—many of the expansion’s major features, such as Garrisons, won’t be available until a later point in the testing process. This early phase of testing will help us ramp up for our larger beta phase later on, when we’ll be inviting more players.
For nearly 20 years, Blizzard games have used a file format called Mo’PaQ (MPQ for short) as a way to compress and store game files. We’ve been able to introduce some great new technology using MPQ, such as our streaming client, but we’ve really pushed the file format far beyond what it was ever intended to be used for. Today, it’s become the source of a number of technical limitations for World of Warcraft.
To address these limitation and help us develop new technologies that will improve everyone’s game experience for years to come, we’re introducing a new proprietary file format that we call CASC (Content Addressable Storage Container). We’ll be using this new format in the Warlords of Draenor alpha and beta tests, and our intent is to convert everyone to the new format in a pre-expansion patch.
As geeky as it may sound, we’re extremely excited to be moving to this new file format. It provides a ton of benefits not only for us and our ability to support and patch the game, but also for players. Here are just a few of the benefits of the new CASC file format:
We’re already using this file format for Heroes of the Storm’s Technical Alpha test, and we’re looking forward to reaping its benefits for WoW. As we mentioned, the first big step in transitioning all WoW players over will be converting everyone’s World of Warcraft installs to the new file format prior to the expansion. Our goal is to make sure that’s as seamless and painless a changeover as possible, using as much of the existing installed data as possible to reduce additional downloads. We’ll have more info on the file conversion process as we get closer to the launch of Warlords of Draenor.
We’re still early in the Alpha testing process, but if you’re interested in opting in for a chance to participate in the Warlords of Draenor beta test later down the line, let us know you’re interested by creating a beta profile. To do so, log in to your Battle.net® account, go to Beta Profile Settings to download and run the Battle.net System Check tool, and submit (or update) your computer’s specifications. From the Beta Profile menu, make sure that Warcraft is checked, and update your beta preferences. You’re now eligible to be randomly selected for a Warlords of Draenor beta invite at a later stage of the testing process.
As interest grows for the upcoming Warlords of Draenor expansion, please be aware of phishing attempts. Unscrupulous individuals (possibly working for the Iron Horde) may send out falsified emails purporting to be from Blizzard, but are in fact meant to steal your login credentials.

Stay tuned for more information as development and testing progresses for Warlords of Draenor™. This is just the beginning and we’ll have more information to share with you in the near future!
Also battlenet launcher has chat capabilities enabled now!
This is more exciting than most players realize. :) You can't just keep piling more and more content and bigger and bigger numbers into a game. That would be like adding extra stories on top of a foundation that wasn't built for it. Eventually it collapses. This is a strengthening of the foundation which should make the quality of life within the game much better. Trust me, if you want to see how important quality of life is compared to content, just try playing vanilla again.
Seriously excited to see new stuff. The long drought was painful.
About god-damned time!!!!!!>_< almost 2 months of silence, I was going absolutely INSANE.Time to read and feed on much needed news.
mhhhhh... a game that has been running on average graphics ..... i can wait for it....
The party has begun!
I wonder whether the new format means they can hide stuff from dataminers...Whether it's everything or just stuff they want to keep secret.
Addon and mod developers are gonna be pulling their hair out ... 'o.OClient side fixes that don't require patching will lead to alot of things getting broken without warning.
Draenor is coming.
*double checks date to see if it's not an delayed april's fool* ... WOOT! i hope i can try it out when available.although i wish this actually also meant that old forgotten still existent pre-WoD bugs will be addressed.
I agree on the launcher having an invis mode. Most of my friends will still message me, even if I'm in "Busy" mode, so I need an invisible mode so I can do my homework without having to exit the launcher and then go find my authenticator when I want to play again.
