 In the course of implementing web-workers some breaking changes were introduced to the API.
   - The `Quagga.init` function no longer receives the callback as part of the config but rather as a second argument: `Quagga.init(config, cb)`
   - The callback to `Quagga.onDetected` now receives an object containing much more information in addition to the decoded code. (see [data](#resultobject))
-
+  - Added `Quagga.onProcessed(callback)` which provides a way to get information for each image processed.
+  The callback receives the same `data` object as `Quagga.onDetected` does. Depending on the success of the process the `data` object
+  might not contain any `resultCode` and/or `box` properties.
