YouTube, in their latest blog post, has made a list of the new updates made to the popular video sharing site.
Upload Progress Bar: A new Flash uploader now exists for all supported browsers. It comes with a long-awaited (and much-requested) feature: an upload progress bar that lets you know the status of your upload. In the future, expect them to provide the estimated video processing time for a video upload.
Simpler HD Parameter: Now there's an official URL parameter (hd=1) for sharing HD links.
