The WHATWG HTML spec can now be considered a “living standard”.
It’s more mature than any version of the HTML specification to
date, so it made no sense for us to keep referring to it as merely
a draft. We will no longer be following the “snapshot” model of
spec development, with the occasional “call for comments”, “call
for implementations”, and so forth.
Low on hype, high on practicality — that’s why I admire the WHATWG.
