The UEFI 2.7 Spec was recently released, as I’ve mentioned before.  Every time a new version of the spec is released, I have this great idea that I’ll do a write up of all the important new features it contains. Alas, I usually don’t get around to it.

Imagine my surprise then, when I tuned into my Twitter feed to see that Mr. Nikolaj Schlej did an awesome summary, via tweets.  I’ve embedded them below—just browse through them and you’ll have a pretty good summary of all the neat new stuff in UEFI 2.7.  Thanks Nikolaj!
