[Ken Case]

Please bear in mind that writing notes which are meaningful to people other than other developers on the project can take a bit of a mental shift from writing code, so while it's only a few lines it can interfere with a developer's flow (and therefore their productivity) while they're coding.

That said, we certainly do understand the utility of providing those notes and we didn't intentionally stop including them: they just disappeared because I'm the person who usually writes them and I've been busy with some other projects for the last week or so (playing catchup on lots of fronts after returning from WWDC).

Our release notes are up to date again now.
