For those that have a Dropbox account, you can now upload your game’s files directly from your Drobox account.
You can find the new “Choose with Dropbox” button next to the original file upload button:
One other enhancement to uploading has been made as well. If you upload a file with the same name as an existing file it will now override the existing one, but keep all existing statistics about the file. It is not necessary to delete the old file before uploading the new one.
