There have been a number of doc fixes, but they've largely been polish more than brand new things. I've had about ~50 PRs in this release myself, after a quick look, and we had a bunch of community stuff as well.

The specific issue you're talking about is due to using Markdown rather than ReST, basically. We didn't manually link those methods, but probably could.

In general, the API docs could use a lot of work. There's always so much more to do.
