We sometimes need your permission to do what you ask us to do with your stuff (for example, hosting, making public, or sharing your files). By submitting your stuff to the Services, you grant us (and those we work with to provide the Services) worldwide, non-exclusive, royalty-free, sublicenseable rights to use, copy, distribute, prepare derivative works (such as translations or format conversions) of, perform, or publicly display that stuff to the extent reasonably necessary for the Service. This license is solely to enable us to technically administer, display, and operate the Services. You must ensure you have the rights you need to grant us that permission. [Emphasis added]

By submitting your stuff to the Services, you grant us (and those we work with to provide the Services) worldwide, non-exclusive, royalty-free, sublicenseable rights to use, copy, distribute, prepare derivative works (such as translations or format conversions) of, perform, or publicly display that stuff to the extent we think it necessary for the Service.
Significantly different. And it was changed for a reason.
