Build 7.1.5 is already out but developers are working on the next update as we speak. The next World of Warcraft 7.2 has made its way to PTR and is available to testers right now. A big portion of World of Warcraft 7.2 is not available to testers yet but it will be announced in the upcoming few weeks. So you have to wait for that.
The current version os focuses on Demon Assaults and overall stability. Players have also been introduced to Pet Battle Dungeon. An early look at the World of Warcraft 7.2 reveals that there are some changes to the Transmog system to track raid and PvP item sets. Some visual improvements are made for Hunters, Death Knights and Balance Druids.
World of Warcraft 7.2 will also offer some changes when it comes to Obliterum Forge. You will no longer need to complete a quest in order to unlock the forge and I think that this will be a change that new players will appreciate but will bum out older players that have already completed the quest.
Players will also be able to change unwanted items for the items that they want. Another cool feature that players needed. This feature is not part of the PTR at the moment but will be coming soon.
It is great to see how quickly developers are creating content for the game and we appreciate that. As of right now there are some cool features in the current build which should be enough to keep users busy till the next update comes out.
It will be interesting to see what new things we will be getting in the new build but seeing how the two updates are not too far apart I do not think that there will be something too drastic. Let us know what you would like to see in World of Warcraft 7.2.
