I just upgraded my camera to the Canon 80D. I understand that I need to update lightroom in order for it to support my new camera's raw files. I have Lightroom 5 and when I check for updates on lightroom it shows none. I don't want to have to convert my files I just want to be able to import them and edit them like I always have.
You need to purchase the Upgrade to Lightroom 6.5, or purchase a subscription to Lightroom CC 2015.5. In either case, you need an operating system that can run this software (Windows 7 or later, MacOSX 10.9 or later), and it must be a 64 bit operating system.
In order to import the images from Canon 80D you need Lightroom 6.5/Lightroom CC 2015.5 or above.
