It seriously takes 30 seconds to do and your done... and while WA probably could update to the latest release the same way and roll out a dot release of the extension, you have to remember that extensive testing has to be done to insure that it will work under all environments. But so far, I can tell you that I have had no problems... just follow the link and you'll be good to go.
Well, not quite. If you changed the file settings manager, which is located in editor/filemanager/connectors/<server_model> to make it work for your client's file upload tasks, you will bluntly overwrite your settings and leave a disfunctional site. And there have been some changes in fckeditor's settings in this config file.
So, to claim it's a 30 second job to update, is simply not true.
