What

A tool that takes files through file_path or files now checks each file's type against an allowed list. The list covers text, JSON, PDF, images, fonts, audio and video. When the documents option is set, a second list is added to it.

Why

Files of types outside the list are checked against it, so not every kind of file is accepted by this tool.
