Differences between Safari for Windows and Safari for Mac

Question

What are the differences from a developer point of view between Safari for Mac and Safari for Windows?

I think it boils down to evaluate differences between (if I missed

Just wanted to add this experience I came across for Safari. Our devs are still going to look into this but not high priority for us since Windows Safari isn't much of our user base unlike Mac. But I think it relates to either (or both) - actual browser low level implementation of Safari by Apple, and/or javascript differences.

Our website recently implemented an HTML5 multiple file uploader. Single file uploads work fine on both versions of Safari. But when uploading multiple files, it fails on Windows. We had two different upload clients & endpoints for the uploader (think A/B testing flow), and one of them provided more details that may or may not point at the cause of the problem. On one of the client & endpoints, the client would send details of the filenames & filesizes of files to upload (as JSON array object) to the server endpoint (as seen via web inspector). On Mac where it worked, filesizes were valid, on Windows, they were 0 bytes.

I think the uploader is JQuery based or some other JS library. But I'm not the dev, so can't be sure. But I have a hunch this issue goes beyond JS libraries...
