Google is rolling out a big update to the Google Earth app, and as usual it's a staged deployment. Never fear, we are here with an APK download. In this new version (8.0) you'll find better 3D images, cleaner maps, KML import, and more.
Google hasn't updated the changelog on the Play Store yet, but there's a whole blog post about Google Earth v8.0. The gist of it is that 3D images will look much better now with the new rendering engine. Roads will also get nicer labels and updated data at the same time as Google Maps going forward. Any KML files you have saved in Drive can also be imported into Earth directly, which is neat.

The APK is signed by Google and upgrades your existing app. The cryptographic signature guarantees that the file is safe to install and was not tampered with in any way. Rather than wait for Google to push this download to your devices, which can take days, download and install it just like any other APK.
