Stats for qtdeclarative (whole repo):

-2944 commits (since v5.1.1, previous number was since v5.1.0 which
was incorrect).
-3 commits had [ChangeLog]*
-I added 25 after my second pass.

That's just 1.1% of the commits requiring changelogs.

Seems to vary a lot by module... or by maintainer. For comparison, my
"changelog threshold" was >=P2 bug affecting a previous version (or
feature) and my manual check was on just the commit logs since v5.1.1
(assisted by my particle-powered tool from the last changelog
discussion ;) ). Another thing to note, about half the commits were
from the v4 branch/repo merge, none of which are changelog eligible.
The continued work on v4 is also a large part of that commit number,
in case you're wondering where all those commits are going.

The * is for some interesting things I noticed. Of the 3 usages, 2 of
them were after Thiago's original email. Which means that if he had
run the script on QtDeclarative as well, he'd have gotten only 1 hit.
2 of them had the wrong module name, and 1 of them was arguably
ineligible (but I'm still following that up). So there's still quite
the manual pass needed, even if [ChangeLog] adoption picks up.
