It's been quite a while since last updating the API.
This time, we've added a second way to download user-uploaded files. Instead of files.get_one and then base64-undecoding the content, you can now use new download_url property of files when doing files.get_meta.
For private sites, the URL contains authorization part (?ukey), so that you can simply download the file without a need of using browser with cookies. The URL is valid for 3 to 6 minutes.
