So the text is kind of out of place for those folks. Also, my experience has been that folks tend not to read the existing text in the file anyway, so they're just as likely to miss this new text as they are to miss the headings (particularly as the release notes get longer and so that text may be scrolled off screen for them).

Noted. Tweaked it slightly. Let me know how you feel about it now.

> Another approach to solve this problem would be to remove the subcategories under the static analyzer heading so it's just a general list of changes to the static analyzer. Or to spread the static analyzer changes out among the other categories. WDYT about a reorganization of some kind instead of adding text like that?

I prefer having a CSA section, because users already expect that section.
Usual clang users don't really care about CSA anyway, so this goes both ways.
