Hi Thomas,

The updates to the release note look fine.
Usually they are brief, containing just enough information to quickly
recognize the function and feature that has changed.
The complete information can be found in the original Jira issue.

Sorry about the lack of an external release note guide, one is needed.
Release notes use Markdown making them a bit more readable.
Looking at release notes from any prior release [1] will give you a good 
as to the typical scope and wording.

Closing the release note as "Delivered" marks it ready for an
editorial pass made before the release notes are published
with the GA release.

Thanks, Roger
