Microsoft publishes Windows Phone 7.8 change log.

The Windows Phone 7.8 update rollout started yesterday with reports from users that the update notification has popup on their devices. So far things seem to go well. The update is indeed being pushed to all Windows Phone 7.5 devices including first generation HTC Mozart to the HTC Radar and, of course, the Nokia Lumia devices. All? No, not all devices since the HTC HD7 and the AT&T Titan 2 have been left out. There has been few to no information about the latter device getting the update. On the other hand, HTC took to twitter to announce that they have no plans to release the update for the HD7. I don't worry too much about the HD7 which seem well poised to embrace the same path as the HD2; the device that has more lives than a cat.

After pushing the Windows Phone 7.8 update yesterday, Microsoft, today has published the change log. Check out the changes below:
