This isn't something that most people should ever have to do.

The browser cache should keep the power.js file up to date since the request for the file (should) always be http:://www.wowhead.com/widget/power.js . you can view your own browsers file cache and see that there (should) is only one copy of the above file and view it's last modified (downloaded) time.

Now, im not saying dont do this or you're wrong to do this, it's just that this isnt a reason to update the plugins XML file.

I also cannot find anywhere on the wowhead.com site that describes anything that wowinsider claims.
