We will soon begin limited testing on updates to some Battle.net functionality (mainly communication and login). As a part of this process, you may notice some minor Battle.net-related UI changes while logged in to Diablo III, World of Warcraft, and StarCraft II.
Patch 1.0.6 for Diablo III includes some of the data for this testing but will not impact your play experience. Similar testing-related data will be patched into World of Warcraft and StarCraft II in the future.
Please note that at this stage the testing is limited, but we’ll keep everyone updated and invite you to help us test the changes as soon as we can. We look forward to sharing more information about what’s in store for Battle.net in the future, so stay tuned.
