Are updates for Office Web App Server 2013 cumulative or not? If not cumulative, is there a requirment install all previous releases of updates before intalling the latest update (i believe August is the latest)?
It seems confusing on the version of updates as well. For instance, I found 2 April 2013 updates, not sure which one is the right version? Please advise.
KB 2810007 - http://support.microsoft.com/kb/2810007/en-us (Description of the Office Web Apps Server 2013 update: April 9, 2013)
And then I found under "Office 2013 cumulative update for April 2013", there is another KB for April update although the title is named "hotfix package" only:
KB 2799821 - http://support.microsoft.com/kb/2799821 (Description of the Office Web Apps Server 2013 hotfix package (Wacserver-x-none.msp): April 9, 2013)
