 ## [12.0.0](https://github.com/ckeditor/ckeditor5-build-decoupled-document/compare/v11.2.0...v12.0.0) (2019-02-28)
 
 We are happy to report the release of CKEditor 5 v12.0.0. This release introduces a new editor (called "[Balloon block editor](https://ckeditor.com/docs/ckeditor5/latest/examples/builds/balloon-block-editor.html)"), the [editor content placeholder](https://ckeditor.com/docs/ckeditor5/latest/features/editor-placeholder.html) and support for inline widgets (watch [this PR](https://github.com/ckeditor/ckeditor5/pull/1587) for updates). In addition to that we enabled media embeds and images in tables and resolved the issue where `editor.getData()` returned `<p>&nbsp;</p>` for empty content (now it returns an empty string in this case).
