I downloaded this mapping today.
And it show Version 1.0.0 on the download button. The version I got was 1.1.0. Ah, and it shows the latest and correct version up top. Maybe just a small issue with the button?
Also, is there a plan to show a mapping version history of some kind? Maybe just an "Older versions of this mapping" display on the right, where these versions are available to access in this manner. However, only the newest versions are available in the search on the front page.
