MacBook Air (11-inch, Early 2014)

Hello,

I recently purchased a top-end (i7 Processor, 8GB RAM, 512 GB Flash Storage) MacBook Air 11" model. When I opened the box and checked 'About This Mac', I noticed that the mac is a '11-inch, Mid 2013' series vis-a-vis '11-inch, Early 2014' series. However, when I see this link https://www.apple.com/pr/library/2014/04/29Apple-Updates-MacBook-Air.html , it says that Early 2014 series was release in Apr 2014. I have been told by the Apple Store that there is NO 'Early 2014' series for the top-end MacBook Air11" model. However, when I see this link MacBook Air (11-inch, Early 2014) - Technical Specifications, it says that Early 2014 series is available for the top-end model, i.e., i7 processor, 8GB RAM, 512 GB Flash storage.

Can Apple please confirm their official position on the availability of an 'Early 2014' series for the top-end model (i7 Processor, 8 GB RAM, 512 GB Flash Storage).

Highly appreciate a quick response. Thanks!

Regards, Bebin
