Tuesday is 10 Hour Maintenance, 1.0.7 Not Scheduled
Battle.net upgrades coming on Tuesday, but patch 1.0.7 will have to wait a while longer
Jump past the break for the specifics.
The main announcement on Saturday was of Diablo III servers and the other services scheduled for 10 hours, on Tuesday, December 11.
Thank you for your patience.
Diablo III maintenance for 10 hours is unusual, when there isn't any patch to apply or other serious work being done on the servers. When looking over at the World of Warcraft servers, it turns out they're reporting the same schedule for maintenance over there. There was clearly some work being done across Blizzard properties to necessitate this.
More details were given by a blue post on the European forums, discussing the Tuesday maintenance:
Patch 1.0.7 might surface. Hopefully.
This particular maintenance is mostly addressing some fixes/upgrades to battle.net as far as I am aware... while patch 1.0.7 is on the way for sure, no date has been set for it yet.
The battle.net upgrades mentioned there, are related to some changes that went in with the Diablo III 1.0.6 client patch, that weren't activated yet. This was announced when 1.0.6 went live:
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.
The battle.net upgrades coming in the next Blizzard game release, StarCraft II: Heart of the Swarm point to a lot of work being done on battle.net in general. While big upgrades aren't coming right now to the Diablo III battle.net functionality, there will be some minor changes made across Blizzard's big games, to keep them in sync.
There will also likely be Diablo III hotfixes applied to the servers during the long maintenance period. One issue that will probably be resolved is Error 45008, which has been popping up lately in game when a player tries to report another account for spamming. The word from Blizzard's technical support about the issue:
So while we wait for more details on what to expect in the major patch 1.0.7, there are at least some fixes and minor upgrades going in. We'll keep an eye out for any more info on the next batch of Diablo III updates.
