Looks good! 👍

I'm confused as to what happens in which PR, so I'm just going to say the same thing on this one:

@ralfhandl can you re-do this with the tables not expanded since we agreed on that for the other branches? That will keep the change history so much less polluted on this branch.

Ideally I'd prefer not collapsing the spaces after periods, but I'm not going to my heels in on it (but it does create more noise and makes it harder to find sentence changes in a fixed-width editor).

The "table condenser" is currently only in #4040. @mikekistler has approved it half a dozen times already, and I'd happily merge it and port it to 3.1.1 and 3.2.0 with a second approval.

[ralfhandl]

This is the first part of several PRs to sync 3.2.0 with 3.1.1

• Markdown updates for 3.2.0 #4025 - remove TOC, prettier, markdownlint
• 3.2.0: minor nits #4026 - stylistic harmonization
  • diff to #4025
• 3.2.0: replace "property" with "field" or "keyword" where appropriate #4035
  • diff to #4026

We can merge them one by one, thus minimizing the differences, or just merge the last one with the cumulative changes and close the others.

We'll need an additional diff to 3.1.1 to add the changes we did since the last of these PRs was created.

This isn't exactly accurate but looks nicer than plain text so OK :-)

Merging as @mikekistler has approved before table condensing.
