Yep, as chdavid said! We were updated on Friday morning, but still no indication of what's changed.
I've said it before, but release notes should be published *before* a release so we know areas that have changed and can keep an eye out for any issues/plan for changes we may need to make in tandem.
Having them appear (as is usual) at the same time as a release is irritating but tolerable, but to still be in the dark several days later is just poor.
