No more SDK PDFs?

I can no longer find the PDFs that were included with every previous release of the SDK. Are they gone for good or did I miss their new location?

While it's very nice to have the spec in html form, the PDFs served well as offline documentation.

If we at least could get a PDF of https://developer.garmin.com/fit/protocol/ that would be nice. It's literally a pandoc command away when preparing a new spec release.
