After I have upgraded, the thumbnail setting in the Widget does not work.
It's set to thumbnail size 198x80 px, but is reset to default. Only if I set height to more than 100 it will change the size of thumb in height. It seems stuck on displaying thumbnail as close to a square as possible.
The new visits are not populated in popular posts - it's dead.
The comments and views stats are not displayed on separate line, but just following a looooong line after title. This is a long time bug I hoped was fixed by now.
Naturally I have not upgraded this in my production site, these problems must first be confirmed resolved in test lab.
Production site is version 2.1.4, and I'm unable to have this with version 2.2.1
