The Sitemap XML module generates the Sitemap compliant with the schema defined by sitemaps.org and submits it to search engines.

• added support for '' node default language
• added multi-lingual sitemap support as per https://support.google.com/webmasters/answer/2620865?hl=en
• Fixed some error handling
• Fixed URL generation, which was distinctly screwy
• Fixed Ping service to use full URL, not relative
• Fixed Sitemap entries in Robots.txt to be absolute, not relative (as per spec)

• Copy the SitemapXML.dll into the website BIN directory. Note that this will recycle your app pool.
• In Web.config, check the default language setting on the node.
• Update SitemapXML.config . Note that changes will recycle your app pool.
  • [Optional] Remove the <sitemapVariable name="xmlnsTpl” /> node. It’s not necessary.
  • [Optional] On your Site nodes, specify your languages. E.g. <site name="website" filename="sitemap.xml" serverUrl="www.example.com" languages="en-GB,fr-FR,de-DE " />
  • Check your ‘ProductionEnvironment’ setting.
• Update the nodes for the search services you’re going to ping.
  • Remove Yahoo. You don’t need it, it uses Bing now.
  • Update Live Search to use Bing. Change the Name, and set the URL to: http://www.bing.com/webmaster/ping.aspx?siteMap=
• Make sure that your Robots.txt file does not contain any relative paths to the sitemap.xml

Publish some content and the Sitemap file (and Robots.txt) should update.
