I am not following what your post has to do with my announcement? There were NO upgrade issues mentioned. I was discussing how nicely the InfiniteWP plugin I started using worked in upgrading plugins and WP versions in a matter of minutes. Also, it looks like you copied and pasted something from the web, as the versions your post mentions are quite old.

I just finished upgrading 46 WordPress websites to WordPress 3.0
.... Wordpress just released 3.9.1
