Mind the default values and special behavior in the `extractContents()` method! * Fixed issues where IDs were lost on copy&paste and drag&drop. * Toolbar configurators: * [#13185](http://dev.ckeditor.com/ticket/13185): Fixed: Wrong position of the suggestion box if there is not enough space below the caret. * [#13138](http://dev.ckeditor.com/ticket/13138): Fixed: The "Toggle empty elements" button label is unclear. * [#13136](http://dev.ckeditor.com/ticket/13136): Fixed: Autocompleter is far too intrusive. * [#13133](http://dev.ckeditor.com/ticket/13133): Fixed: Tab leaves the editor. * [#13173](http://dev.ckeditor.com/ticket/13173): Fixed: [`config.removeButtons`](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-removeButtons) is ignored by the advanced toolbar configurator.

More about the change in the [Browser Compatibility](http://docs.ckeditor.com/#!/guide/dev_browsers) guide. * [#13398](http://dev.ckeditor.com/ticket/13398): Renamed `CKEDITOR.fileTools.UploadsRepository` to [`CKEDITOR.fileTools.UploadRepository`](http://docs.ckeditor.com/#!/api/CKEDITOR.fileTools.uploadRepository) and changed all related properties. * [#13279](http://dev.ckeditor.com/ticket/13279): Reviewed CSS vendor prefixes. * [#13454](http://dev.ckeditor.com/ticket/13454): Removed unused `lang.image.alertUrl` token from the [Image](http://ckeditor.com/addon/image) plugin. ## CKEditor 4.5 Beta New Features: * Clipboard (copy&paste, drag&drop) and file uploading features and improvements ([#11437](http://dev.ckeditor.com/ticket/11437)). * Major features: * Support for dropping and pasting files into the editor was introduced. Through a set of new facades for native APIs it is now possible to easily intercept and process inserted files. * [File upload tools](http://docs.ckeditor.com/#!/api/CKEDITOR.fileTools) were introduced in order to simplify controlling the loading, uploading and handling server response, properly handle [new upload configuration](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-uploadUrl) options, etc. * [Upload Image](http://ckeditor.com/addon/uploadimage) widget was introduced to upload dropped images. A base class for the [upload widget](http://docs.ckeditor.com/#!/api/CKEDITOR.fileTools.uploadWidgetDefinition) was exposed, too, to make it simple to create new types of upload widgets which can handle any type of dropped file, show the upload progress and update the content when the process is done. It also handles editing and undo/redo operations when a file is being uploaded and integrates with the [notification aggregator](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.notificationAggregator) to show progress and success or error. * All drag and drop operations were integrated with the editor. All dropped content is passed through the [`editor#paste`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-paste) event and a set of new editor events was introduced — [`dragstart`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-dragstart), [`drop`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-drop), [`dragend`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-dragend). * The [Data Transfer](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.clipboard.dataTransfer) facade was introduced to unify access to data in various types and files. [Data Transfer](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.clipboard.dataTransfer) is now always available in the [`editor#paste`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-paste) event. * Switched from the pastebin to using the native clipboard access whenever possible. This solved many issues related to pastebin such as unnecessary scrolling or data loss. Additionally, on copy and cut from the editor the clipboard data is set. Therefore, on paste the editor has access to clean data, undisturbed by the browsers. * Drag and drop of inline and block widgets was integrated with the standard clipboard APIs. By listening to drag events you will thus be notified about widgets, too. This opens a possibility to filter pasted and dropped widgets. * The [`editor#paste`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-paste) event can have the `range` parameter so it is possible to change the paste position in the listener or paste in the not selectable position. Also the [`editor.insertHtml()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-insertHtml) method now accepts `range` as an additional parameter. * [#11621](http://dev.ckeditor.com/ticket/11621): A configurable [paste filter](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-pasteFilter) was introduced. The filter is by default turned to `'semantic-content'` on Webkit and Blink for all pasted content coming from external sources because of the low quality of HTML that these engines put into the clipboard. Internal and cross-editor paste is safe due to the change explained in the previous point. * Other changes and related fixes: * [#12095](http://dev.ckeditor.com/ticket/12095): On drag and copy of widgets [the same method](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-getSelectedHtml) is used to get selected HTML as in the normal case. Thanks to that styles applied to inline widgets are not lost. * [#11219](http://dev.ckeditor.com/ticket/11219): Fixed: Dragging a [captioned image](http://ckeditor.com/addon/image2) does not fire the [`editor#paste`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-paste) event. * [#9554](http://dev.ckeditor.com/ticket/9554): [Webkit Mac] Fixed: Editor scrolls on paste. * [#9898](http://dev.ckeditor.com/ticket/9898): [Webkit&Divarea] Fixed: Pasting causes undesirable scrolling. * [#11993](http://dev.ckeditor.com/ticket/11993): [Chrome] Fixed: Pasting content scrolls the document. * [#12613](http://dev.ckeditor.com/ticket/12613): Show the user that they can not drop on editor UI (toolbar, bottom bar). * [#12851](http://dev.ckeditor.com/ticket/12851): [Blink/Webkit] Fixed: Formatting disappears when pasting content into cells. * [#12914](http://dev.ckeditor.com/ticket/12914): Fixed: Copy/Paste of table broken in `div`-based editor. * Browser support.<br>Browser support for related features varies significantly (see http://caniuse.com/clipboard). * File APIs needed to operate and file upload is not supported in Internet Explorer 9 and below. * Only Chrome and Safari on Mac OS support setting custom data items in the clipboard, so currently it is possible to recognize the origin of the copied content in these browsers only. All drag and drop operations can be identified thanks to the new Data Transfer facade. * No Internet Explorer browser supports the standard clipboard API which results in small glitches like where only plain text can be dropped from outside the editor. Thanks to the new Data Transfer facade, internal and cross-editor drag and drop supports the full range of data. * Direct access to clipboard could only be implemented in Chrome, Safari on Mac OS, Opera and Firefox. In other browsers the pastebin must still be used. * [#12875](http://dev.ckeditor.com/ticket/12875): Samples and toolbar configuration tools. * The old set of samples shipped with every CKEditor package was replaced with a shiny new single-page sample. This change concluded a long term plan which started from introducing the [CKEditor SDK](http://sdk.ckeditor.com/) and [CKEditor Functionality Overview](http://docs.ckeditor.com/#!/guide/dev_features) section in the documentation which essentially redefined the old samples. * Toolbar configurators with live previews were introduced. They will be shipped with every CKEditor package and are meant to help in configuring toolbar layouts. * [#10925](http://dev.ckeditor.com/ticket/10925): The [Media Embed](http://ckeditor.com/addon/embed) and [Semantic Media Embed](http://ckeditor.com/addon/embedsemantic) plugins were introduced. Read more about the new features in the [Embedding Content](http://docs.ckeditor.com/#!/guide/dev_media_embed) article. * [#10931](http://dev.ckeditor.com/ticket/10931): Added support for nesting widgets. It is now possible to insert one widget into another widget's nested editable. Note that unless nested editable's [allowed content](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget.nestedEditable.definition-property-allowedContent) is defined precisely, starting from CKEditor 4.5 some widget buttons may become enabled. This feature is not supported in IE8. Included issues: * [#12018](http://dev.ckeditor.com/ticket/12018): Fixed and reviewed: Nested widgets garbage collection. * [#12024](http://dev.ckeditor.com/ticket/12024): [Firefox] Fixed: Outline is extended to the left by unpositioned drag handlers. * [#12006](http://dev.ckeditor.com/ticket/12006): Fixed: Drag and drop of nested block widgets. * [#12008](http://dev.ckeditor.com/ticket/12008): Fixed various cases of inserting a single non-editable element using the [`editor.insertHtml()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-insertHtml) method. Fixes pasting a widget with a nested editable inside another widget's nested editable. * Notification system: * [#11580](http://dev.ckeditor.com/ticket/11580): Introduced the [notification system](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.notification). * [#12810](http://dev.ckeditor.com/ticket/12810): Introduced a [notification aggregator](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.notificationAggregator) for the [notification system](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.notification) which simplifies displaying progress of many concurrent tasks. * [#11636](http://dev.ckeditor.com/ticket/11636): Introduced new, UX-focused, methods for getting selected HTML and deleting it — [`editor.getSelectedHtml()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-getSelectedHtml) and [`editor.deleteSelectedHtml()`](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-method-getSelectedHtml). * [#12416](http://dev.ckeditor.com/ticket/12416): Added the [`widget.definition.upcastPriority`](http://docs.ckeditor.com/#!/api/CKEDITOR.plugins.widget.definition-property-upcastPriority) property which gives more control over widget upcasting order to the widget author. * [#12036](http://dev.ckeditor.com/ticket/12036): Initialize the editor in [read-only](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-property-readOnly) mode when the `<textarea>` element has a `readonly` attribute. * [#11905](http://dev.ckeditor.com/ticket/11905): The [`resize` event](http://docs.ckeditor.com/#!/api/CKEDITOR.editor-event-resize) passes the current dimensions in its data. * [#12126](http://dev.ckeditor.com/ticket/12126): Introduced [`config.image_prefillDimensions`](http://docs.ckeditor.com/#!/api/CKEDITOR.config-cfg-image_prefillDimensions) and [`config.image2_prefillDimensions`](http://docs.ckeditor.com/#!/api/CKED
