@Stefan, it seems that 10.1.822 has removed tutorial links from the bottom of reference pages. Here's what I had before:

And here's what I have now:

I know that the style of that Tutorials header did not fit in, but that is just a minor stylistic thing. Tutorials are essential for packages, and they should be easily discoverable from the main doc page of a package (which is usually the guide page). Can this section please be restored? Otherwise, is there anything I can do to restore this Tutorials section, short of looking into the DocumentationBuild source and hacking it within docbuild.xml with some live patching?

If anyone else has installed 10.1.811 and is struggling to go back to 10.1.757, it turns out to be possible because Eclipse seems to cache previously installed versions of its plugins.

Go to Help -> Installation Details. Select the Installation History tab. Select a restore point, and click Revert.

Thanks for the clarification! In case you haven't seen this question yet, do you have the answer for it?

Maybe I misunderstood your response, but just in case: I do not see the links in 11.0.1 either. This shows that they are not hidden by the stylesheet. The DocumentationBuild package that is bundled with 10.1.822 simply does not include these links on guide pages.

The official Mathematica documentation did not have tutorial links at the bottom even in the 10.0-11.0 style documentation. It only had these links in a dropdown menu at the top. This menu was removed in 11.1. This means that guide pages have no links to tutorials whatsoever in 11.1. I think this is a usability problem in the 11.1 built-in documentation. But it is a distinct problem from what I was asking about here: now I am asking only about how to have these links in my own documentation.

Stefan, Thank you. My documents built from 10.1.882 can display correctly now.

Thank you for the clarification. Could you please post an update in this thread when it has been fixed, to signal that it is now safe to update the plugin?
