With the release of iOS 8 just over a week now, users wanting to upgrade should be aware of enabling the new iCloud Drive feature right away (see article below). It should be stated that the other iCloud features work as normal, and have a few new settings that users may want to take advantage of, including the “Send Last Location” security setting in Find My iPad/iPhone that will (as the title implies) pinpoint the last network location the device was seen on if logging into http://icloud.com (this will only work if the user has signed into iCloud on a iOS device). More information about the Send Last Location setting can be found on this page.

One of the many new features in iOS 8 is iCloud Drive, which is basically Apple’s take on Dropbox. Unlike how iCloud has functioned in the past, iCloud Drive acts as the hub for all of the files stored by your apps in the cloud.
It’s a great idea, but most people should avoid enabling it during the iOS 8 installation process today.
That could mean a serious headache for anyone who’s not running both iOS 8 and the private or developer beta of OS X Yosemite. Unless you have Yosemite running on your Mac, iCloud Drive will do you more harm than good.
If you’re ready to take the plunge, iCloud Drive can be enabled in Yosemite under the iCloud panel in System Preferences. It can be turned on at any time in the iCloud section of the Settings app in iOS 8 as well.
It could be the case that you only want to use iCloud Drive on your iOS 8 device, and then you obviously have nothing to worry about. But the main benefit of iCloud Drive is the access it gives you to files on all of your devices, and that won’t apply for everyone on the Mac until Yosemite’s public release in October.
