If you go to Adobes website you will find it difficult not to download the CC version, and will be offered it first,, as the perpetual one is "hidden " from casual view. 5.71 is the latest version
AFter reading your post again, I'm assuming that you're not being sarcastic!
Thanks. I did update from 5.7 to 5.7.1

Lightroom is available through the creative cloud subscription plan, but it is not called Lightroom CC. It is the same program as the standalone installation. It's just licensed differently, and it is identified in the Help/About Lightroom as version 5.7.1 (at least right now).
