I noticed the announcement news are removed from the news page when they become older then $g_news_view_limit_days. I guess the announcement has to remain on the top independently from the date. When the author would like to remove the news he has just to unset the annoucement flag.
Moreover in case of BY_DATE news, there is no control of the number of news and no page prev, page next is working.
I tried to fix all the point in the patch attached (against CVS HEAD).
Summarising:
when the option $g_news_limit_method is BY_DATE:
- annoucement always on top (independently from the issue date)
- news limit to $g_news_view_limit in any case
when the option is BY_LIMIT:
- annoucement always on top (up to $g_news_view_limit)
- news limit to $g_news_view_limit
