I had observed that your new version slowly index and Ping the pages in Google, Bing, Yahoo, and Ask. This Monday I bought new blog (oddees.net) I installed last version of plugin, I saw that On Wed new blog get place in search engines.
While my old blog (breakingnews24hrs.net) before installing new version had 29K index pages now it decrease to 25K. In Google webmaster tool I submitted the sitemap_index.xml. I don't understand the reason of this problem.
