You can find the full features here. Here's a quick rundown of the news:
CCC 5 is now available. CCC 5 requires macOS 10.10 or later and is a paid upgrade. CCC 5 will be compatible with macOS 10.13 High Sierra when it is released.
CCC 5 is full of new and improved features. They include guided setup and restore, backup health check, new task grouping and sorting options, nifty new task history trend charts, a new task filter interface, task importing and exporting and more!
Don't forget to make a bootable CCC backup before you upgrade to High Sierra and keep your backup drive unplugged until you're sure you don't want to downgrade. We also recommend reading learning more about CCC & APFS and our recommendations before you convert to APFS
The developer notes that CCC 4 will be qualified for High Sierra for those who are not ready to upgrade. Version 4 will offer full functionality for HFS+ volumes, but limited support for APFS volumes.
