@zygoloid: Do you have specific pointers?
Both the [array] and [util.smartptr] modifications have their xrefdelta entries, as do my proposed reverse_iterator changes.

I don't know the answer, but an easy way to find out is to compare the autogenerated xref data file from before and after and see if anything went away.

The list of all labels can be produced using:
sed '/glossaryentry/s/^\\glossaryentry{\([^@]*\)@.*$/\1/' xrefindex.glo | sort

Doing this on the "c++17" branch yields (for future reference):
glo-17.txt.gz

Comparing against HEAD shows a single missed update, which is the deprecation of [util.smartptr.shared.atomic].
