Certainly. But my sentence about "Numerous performance improvements"
already mashes down dozens of other it-just-works-better-now
performance improvements. Wny call out that one in particular?

If I had to pick out just one, I might actually lean towards mentioning
86dc90056, which might change users' calculus about how many partitions
they can use. (But I may be biased about that.)

Perhaps, but on those grounds, the business about reducing B-tree bloat
doesn't belong in the press release either. Anyway I'm not sure the
audiences are so different --- if I thought they were, I'd not have
started from the press release.

My feeling is that the initial summary in the release notes is meant
to be a 10000-meter overview of what's new in the release. As soon
as you get past that bullet list, you find yourself right down in the
weeds, so an overview is good to have. The press release can afford
to fly a little lower than 10000 meters, though not by all that much.
