## CKEditor 4.1 RC
* [#9829](http://dev.ckeditor.com/ticket/9829): Data and features activation based on editor configuration.
Brand new data filtering system that works in 2 modes:
* based on loaded features (toolbar items, plugins) - the data will be filtered according to what the editor in its
current configuration can handle,
* based on `config.allowedContent` rules - the data will be filtered and the editor features (toolbar items, commands,
keystrokes) will be enabled if they are allowed.
See the `datafiltering.html` sample, [guides](http://docs.ckeditor.com/#!/guide/dev_advanced_content_filter) and [`CKEDITOR.filter` API documentation](http://docs.ckeditor.com/#!/api/CKEDITOR.filter).
