In version 2.0.3, whenever I uploaded a file, the file name will be left untouched, i.e. "File Name.jpg" will still be "File Name.jpg" in the server.
However, when I upgraded it to 2.0.4, the file name is automatically change for each new upload, i.e. "File Name.jpg" to "file-name.jpg".
I prefer to have the old option back. It will be nice if WordPress allows the user to specify the name format for uploaded files. I've searched for a plugin for this, with no avail.
Most people will not fret on this, but the main reason why I switched to WP in the first place was because of the file name integrity.
Thank you, and keep up the good work.
