Too much data or trouble shooting mode?

[flash760]

Since upgrading to CC620 I have had what looks like some sort of troubleshooting aid or something like a var_dump at the bottom of both my admin page and a store page (whether or not I the front end turned on). Have I missed some sort of choice or checkbox somewhere that I should toggle? Below is a highly shortened rendition of the data that appears on every page:

This is because you have debug mode turned on in your stores settings (Advanced section). Just turn it off.

Al,

I posted here because it has happened only since the upgrade so it looks to me like an installation/upgrade issue. Am I wrong?
