April Update for Power Map Adds Audio, Clears Confusion
On April 18 Power Map got updated, although if you have a Click-to-Run installed version of Office 365 Pro, you would never know it since these updates are pushed automatically. Here is a link describing the new features, other than some cosmetic updates, ability to add audio to a tour is probably one of the most salient ones.
Those who installed Power Map Preview on a non 365 Pro version of their office were probably getting worried that this Power BI feature will no longer be available after May 31, 2014. Well, Microsoft has answered your prayers by removing the Preview Expiration. So the extended version of Power Map Preview will continue to be available to download past this spring although only the supported (365 Pro) version of Power Map will be receiving future regular updates.
