Hello!
When I downloaded the "update.zip" it also includes files that are not updated (not mentioned in the changelog), so if I upload all these files it will also overwrite files that are modified by me, for example, most of the templates and so on. So it is quite hard work to get everything to work in correct way again. Also when doing this "restore" operation I may also accidentally overwrite some new flies with older backup files, in order to get the site to look like it used to be before the update. So to sum up, at the moment the update caused more problems than solved, for me.
If it is possible, in next update, please DO NOT add files that are not updated, or just let me know if I am doing anything in a wrong way, cause it is clearly stated that "Upload all of the files so your site".
