All those who were facing sitemap indexing problem, please wait for few days. All your posts will index soon, it will takes some time depends on site to site….If your articles crawl per day then your all posts indexed in 2 days after updating this plugin, otherwise wait for at-least 1 week.
Your all posts not de-indexed after updating to new version. so be patience.
Why you are worried so much, just wait for few days. I also update to 4.0.2 and within 2 days my all posts indexed properly. It will takes some time.
So do not worry so much because if your sitemap showing 0 indexing then give some time, your previous posts not de-indexed from google. Even if you do not use sitemap, google also crawl your articles but slowly.
So just wait for few days, this updated version is very good as compared to previous version.
