Same. The blog says, "Download & Transfer via USB" option will no longer be available, but "You can continue to sideload e-books on your Kindle via USB cable".

What is the difference? How is sideloading different from normal USB Transfer?

You can transfer books you make or download elsewhere to the reader over USB but Amazon is no longer going to let you download the files from them. Amazon books will only transfer directly to your reader over Wi-Fi.

Thanks for clarifying.
