Difference between 2.x and 3.x? Missing "multipart_params" with upload.

[Daijobou]

New version 3.1.2 is not a out-of-the-box replacement for my older version 2.2.1. Its look like this setting not work anymore? With upload 2.2.1 I can see "multipart_params" in Header, in 3.2.1 this is complete missing.

uploader = new plupload.Uploader({
    runtimes : 'html5,html4',
    browse_button : 'upload',
	url: 'ajax/upload/image',
    max_file_size : '1mb',
    multi_selection: false,
    filters : {
        mime_types: [{title : 'Image files', extensions : 'jpg,jpeg,gif,png'}]
    },
init: {
    BeforeUpload: function(up, files)
	{
 	    up.settings.multipart_params =
 	    {
			uname: username,

Is here a file/doc that show the differences and what to do or is this a issue in 3.1.2?

EDIT: In 3.x its marked as "deprecated"

plupload/js/plupload.dev.js

Line 3326 in d1aee32

multipart_params: {}, // deprecated, use - params,

Just use params instead?

version v3.1.2 , currently doesn't have all features of 2.3.6 .
its better to use 2.3.6 in projects (it is stable and The latest the greatest)

[cocochepeau]

OK. Indeed, that's what I'm currently doing btw. I had other issues related to 3.x.

Is Plupload still a living project?

i think its better to use dropzone or jquery file upload.
