You may want to compile a new sitemap.xml just in case and resubmit it to google/yahoo/bing. I always do when I change my stuff around.
i have joomla website, you dont need to genrate a sitemap becose joomla automatically update your sitemap thats your sitmap yoursite.com/index.php?option=com_xmap&sitemap=1&view=xml&no_html=1 it's accepted by google webmaster look my sie maroc37.com/index.php?option=com_xmap&sitemap=1&view=xml&no_html=1 sorry for my bad english
install xmaps for joomla, create a webmaster tools account, then just add the links, or you can just simply write in to the robots.txt
