Maybe they'll only support version that were released from the date that library was added to the CDN. In other words, hopefully once a library+version are added to the CDN, it's supported for a long long time.
Digging deeper, I see that libraries are added via pull request and that the Nivo Slider library was added 11 days ago. Other libraries that have been there longer (such as jQuery) continue to have old versions.
