What's new in 2.8.5.0:

Scale the GUI - TWRP can read the theme's resolution and scale it up or down to fit the theme to your screen's resolution
Backups can now be cancelled while the backup is in progress (does not include restore because we don't want to leave your device in a bad state)
Improve thread handling and move input handling into the main rendering thread to improve stability
Make MTP work even if unplugged and plugged back in
Unify scrollable list code and make kinetic scrolling feel more natural
Fix handling of mapped zip files for OTA updates (CM12 updater)
USB keyboards should now work on all devices that support USB host mode via a USB OTG cable
