We recently commented that the iTunes / App Store has gained a new look to keep up with the changes in iTunes 12. All of this, of course, due to the arrival of OS X Yosemite.
Today was, finally, the turn of the Mac App Store.
As we can see above, all sections of the OS X app store (Highlights, Top Charts, Categories, Purchases and Updates) look very similar to the new operating system.
Now, only the iBooks Store is missing.
