Now that we are past prototype stage and in late beta, it's time to change the top line message to reflect that change on the New Pages Feed.
I recommend we change the first sentence as so:
'This is a beta version. Key features are still in development. Learn more · Leave feedback'
(instead of 'This is a prototype, not a final product.')
Also, let's replace the red text color of this top line with a less strident dark gray or black.
