Thank you for this review. Although I can agree to many of these changes, I do not think it is wise to make them so close to the release date, when translation teams have updated (or are in the process of updating) the translations in preparation of the Release.
Release Notes should be string frozen at some point, they should not be a loving target. These type of stylistic changes ("&debian;" to "Debian"") should in my opinion, be done post-release.
At the very least, translation teams should be informed (specially those currently close to or at 100% ). So they are aware and have time to do/plan a last review/update before $RELEASE.
There are currently 9 (out of 19) translations which are over 90%)
