changeset 5839:6670881fb389 draft
(svn r8409) -Regression (r8049): When the latest news was deleted, the news queue wrapped back to the oldest item, showing all news again.
-Regression [FS#573] (r8049): ShowLastNewsMessage could show an out-of-bounds news item because it did not checked if a previous item actually existed the first time it is called (forced news is INVALID_NEWS).
