Some version changes have new or updated JavaScript and CSS code within the template, which all browsers love to cache (keep a temporary copy). If you have updated your templates and are still experiencing problems on the front end of your site (images are not aligning, cannot process any orders, etc) try clearing out you browser cache.
If you are using IE then you will need to go to 'Tools' -> 'Internet Options' -> 'General' -> click on the delete button in the 'Browser History' section -> click on the 'Delete files ...' button.

If you are using Safari then you will need to go to 'Edit' and then 'Empty Cache ...'
