I just logged into my Acer Iconia Tab W500 which is running the Windows 8 Consumer Preview and noticed updates available for the Metro Mail, Calendar, People and Messaging app as well as the Metro Photo app.
I am not sure what the updates include but after installation my Office 365 Exchange email account was deleted in the update without warning and my Twitter account was also disconnected in the People App.
I seem to recall a lot of folks having problems concerning adding a Gmail account and with this update I was able to do so easily.
Suggestion recommendation for Windows Store – list of changes for updates helps the end user make an informed decision to apply an update instead of doing so blindly.
If anyone tracks down a changelog for these updates please let us know.
