2.3: 22-September-2012. Show a greyscale animation while uploading a picture (except if it's pasted in Firefox)
Compatiblity with CKEditor 4 beta

Configuration options for the drag-over shadows.
Integration with CKEditor 4.1 data filtering
3.0: 26-April-2013. Two buttons for the toolbar to add files or images for those users that don't like to drag things :-).
Fix problems in CKEditor 4 if setData is called on the editor
Use correct URL for upload if it lacks query string parameters.
3.1: 4-May-2013 Adjusted the ACF for IE8 and IE9
The events have been renamed to "simpleuploads.startUpload" and "simpleuploads.endUpload" and now the startUpload can be used to cancel an upload
3.2: 1-June-2013 Adjusted the regexp for detection of uploads to take care of systems that lack the status message.
Added a console warning if the upload url hasn't been set in the configuration of CKEditor.
Add a space to separate links when dropping several files (not images).
Fixed bug in IE10 on drop of multiple files.
3.3.1: 23rd-July-2013 Changed the "100%" text after file has been sent to "Processing..." (it can be modified in the lang file)
Readjusted the detection of file upload name to take into account apostrophes again

4.0: 18-November-2013

According to your previous customizations, the upgrade can be very easy or require a little bit of attention.
Added support to specify extra fields during uploads (for example to support anti-CSRF tokens)
Replace the QuickUpload buttons in all the CKEditor dialogs with one-click buttons
Allow to drop files on the dialogs that have a quick upload of file browser options
Those uploads provide an upload progress bar, cancel button and allow the same features as the rest of uploads (verify the file for size, extension, etc.. before starting the upload, modify the upload url, add extra fields...)
Handle pasted images for Chrome and IE11 in the Paste dialog (remember that it's easier if you just Ctrl+V on the main document)
Added cancel button for images dropped on the editor
Added progress and cancel options for files dropped on the editor

Improved compatibility with CKEditor 4.3 and the new Widgets
Improved compatibility with IE 11 (several adjustments)
4.1.0: 7-December-2013
Enhance the toolbar buttons to preserve better the existing content:
- If an image is selected, picking a new one will preserve its attributes
- If the selection is in a link, picking a file will change only the href of the link
- If there's some text selected, picking a file will convert it to a link
Apply similar checks on the drop target:
- If an image is dropped over an existing one, replace the source
- If a file is dropped over a link, replace the href
During a drop, if the Shift key is pressed, create a link (a) instead of an image (img)
Added new simpleuploads_hideImageProgress option to use always plain text for the uploads instead of the image preview
Handle the third optional parameter in the upload callback for dialogs if it is a function (compatibility with the default uploads)

Handle pasting of images if forcePasteAsPlainText is enabled

Readjusted for changes in the image2 widget
4.2.0: 2nd-march-2014

Based on this event, two new options are available, simpleuploads_convertBmp and simpleuploads_maximumDimensions
More features (local resizing) will be available in a future release.
This event requires asynchronous processing, so maybe there are situations that I didn't test properly, please, cautious with this update for a few days.
