Is there something like a changelog to this? I remember years ago people on freenode #C pointing out tons of mistakes in this [1] and trashing it as a reference to learn from but it seems like it's gone through a decent amount of revision at this point.
Yeah, any history before git is lost aside from what you might find on archive.org.
And I started writing it ages ago, then shelved in it a half-done state. And then it got that probably well-deserved review.
But its former self is barely recognizable since it has been heavily rewritten and expanded over the past 3 years, so I hope the iso-9899.info folks give me a regrade at some point in the future.
