And why are new versions of packages introduced in micro updates? Please don't do this. I expect micro updates to fix bugs, not introduce new versions of packages with lots of possible new bugs.
Maybe MU#13 and the new AWStats package are separate technically, but when I run the autoinstaller to update from Plesk 10.4.4 MU#12 to MU#13 AWStats 7.0 comes along. I would have expected at least an update to 10.4.5 for that.
