WordPress 3.1.2 is now available, Update now!

I just noticed today when I exactly logged in to this blog, On the upper part of this blog admin a yellow messages has been there stated WordPress 3.1.2 is available! please update now, so meaning we can update our old version of wordpress CMS to a better new released one. Actually at this moment I don’t have any ideas on what are the features of this new version of wordpress CMS has, but I heard that this new version had this capability to blocked those spam comments and such kind automatically, but I am not still sure though, I think let me update mine first then I’ll update this post after.
