I just update my two other Blog to MovableType 3.32 from 3.31.
It looks so smooth that I don’t feel any problem.
To update your MT from 3.31 to 3.32.
1) Download the MovableType 3.32 package from SixApart site.
2) Unzip the package file
3) Upload all files into your CGI folder, and confirm to overwrite your original files.
4) When you log in it, you may be prompt to click to update, just click it.
5) Done and you can use the updated MovableType 3.32 now.
