It's easy enough to see what has changed from one version of W3C's HTML5 standard to the next. I can also see the W3C's standards and drafts. But W3C and WHATWG are not the same and since WHATWG maintains a Living standard which is never finished:

how can I keep track of the diffs in the WHATWG HTML Living Standard?

Let's say I want to:

• see what new features exist from the last time I reviewed it
• see what is on the roadmap for inclusion
• see what has changed/dropped

FYI Tracking the WHATWG/html github repo would yield too much noise, but its all I could find.
