Missing date

[Aprillion]

The front-end universe is changing from day to day and it's hard to judge how up to date the information is.

Please display the date of data collection somewhere on top of http://jeffcarp.github.io/frontend-hyperpolyglot/

The versions of each framework at time of recording are already up at the top of each column. Would it be helpful to post the date each version was released?

[Aprillion]

yes, that would probably be the best solution
