Hi @tacaswell @anntzer @ksunden @QuLogic

Could you please take a look at the patch? :)

I'd suggest adding spaces so that the entries ends up in columns.

The sorting and completeness is clearly a huge step over my PR!

(Will not approve because of the relation to my earlier PR.)

Implementation looks good, I went and ran the original report code.

Could argue for test(s?) perhaps, but not too set on what granularity is needed (or if the new things need it if, there were already tests of other things in this list)

CI failures appear to be unrelated (Qt/macos tk, which have been addressed elsewhere)

I am surprised that this did not fail any tests!

There is a wall of tests for mathtext:

Are these worth a whats new?

There are a number of PRs that add and/or correct symbols, so maybe one should create a single What's new that can be appended?

I have included some of the relational operators from the list in #26024.
Is the what's new note required to be added?

I think that at some stage before 3.8 there should be a What's new note in some form. Maybe not listing all the added symbols etc, but stating something more general. Then, this can be updated in the different PRs (for example, it doesn't really make sense to add a note for #26010 , but I can for sure add a line to an existing note about relational operators).

Although this is partly based on a very rudimentary initial PR from me, I think it has diverged enough so that I can fairly review it. (Especially given that nothing has happened in three weeks,)
