 In terms of how to use these methods, they have not changed. The only difference is that it has the capability to take a File object grabbed from the DOM (i.e. `<input type="file" />`). 
 
+File, Blob, and FileList are all valid in the model.  Once set it will be uploaded when ready. 
+
 As the file is being uploaded, a trigger `progress` fires as the browser sends chunks of data.  The `progress` trigger sends a progress status in percents.  
 
 If you want to force not using FormData, add the option `{ formData: false }` and the whether or not you have a file object in the model, it'll try to send it as part of the JSON object.  Opposite is true (for whichever circumstance) is that if you set `{ formData: true }`, it will force the usage of FormData.  Not setting it will leave it automatic and it'll try to detect if there is the file in the model.
