I can give a list of changes – there are many (some 20 css and php files and lots of images) but I would like you to try out a folder comparison tool like WinMerge or its mac equivalent to know what those changes are. Much easier and less prone to errors.
Another way – probably easier is to compare in WinMerge your current setup with the earlier update and see the changes you made and copy them to the new update files before you activate those changes.
If you are into the habit of making extensive changes, may be it is a good idea to push your changes to the free code versioning repo –
and use their client
for file comparison, versioning and management.
If you still need the change list, let me know and I can post here the CSS/PHP changed file list. Thanks
