Changelog

Sourced from ckeditor/ckeditor's changelog.

CKEditor 4.20.2

Fixed Issues:

• #439: Fixed: Incorrect Tab and Shift+Tab navigation for radio buttons inside the dialog.
• #4829: Fixed: Undo reversed entire table content instead of a single cell. Thanks to that fix, multiple changes in a table can be undone one by one.
• #5396: Fixed: Event listeners for popstate and hashchange events on the window, added by the Maximize plugin, were not removed when destroying the editor instance.
• #5414: Fixed: File and image uploaders based on the Upload Widget plugin and Easy Image plugin didn't fire the change event upon finishing upload, resulting in passing incorrect data in form controls for integration frameworks, like Reactive forms in Angular.
• #698: Fixed: An error was thrown after applying formatting to the widget with inline editable and switching to the source mode. Thanks to Glen!

API changes:

• #3540: The startup data passed to the widget's command is now used to also populate the widget's template.
• #5352: Added the colorButton_contentsCss configuration option allowing to add custom CSS to the Color Button menu content. Thanks to mihilion!

CKEditor 4.20.1

Fixed Issues:

• #5333: Fixed: The original name of the uploaded image is not preserved by the Upload Image plugin if the Clipboard plugin has enabled image handling.
• #2881: Fixed: Changing table headers from "Both" to "First column" in the Table dialog does not change the first column cell correctly.
• #2996: Fixed: Table header "scope" attribute is incorrect for the "Headers: both" option in the Table dialog.
• #4802: Fixed: Tableselection caret moves to the previous cell after tabbing into the next cell and then removing its content.
• #5365: Fixed: The value of the config.baseFloatZIndex config variable is incorrectly applied to parent dialog when the child dialog is closed resulting in the dialog overlay covering up the dialog. Thanks to JenoDK!
• #5305: Fixed: Anchor name can invalidly include spaces.

CKEditor 4.20

New Features:

• #5084: Added the config.tabletools_scopedHeaders configuration option controlling the behaviour of table headers with and without the [scope] attribute.
• #5219: Added the config.image2_defaultLockRatio configuration option allowing to set the default value of the "Lock ratio" option in the Enhanced Image dialog.
• #2008: Extended the Mentions and Emoji plugins with a feature option that adds a space after an accepted autocompletion match. See:
  • configDefinition.followingSpace option for the mentions plugin, and
  • config.emoji_followingSpace option for the emoji plugin.
• #5215: Added the config.coreStyles_toggleSubSup configuration option which disallows setting the subscript and superscript on the same element simultaneously using UI buttons. This option is turned off by default.

Fixed Issues:

• #4889: Fixed: Incorrect position of the Table Resize cursor after scrolling the editor horizontally.
• #5319: Fixed: Autolink config.autolink_urlRegex option produced invalid links when configured directly using the editor instance config. Thanks to Aigars Zeiza!
• #4941: Fixed: Some entities got wrongly encoded when using entities_processNumerical = true configuration option.
• #4931: Fixed: Selecting the whole editor content when there is only a list with an empty element at the end inside and deleting it did not delete all list items.

API changes:

• #5122: Added the ability to provide a list of buttons as an array to the config.removeButtons config variable.
• #2008: Added Autocomplete followingSpace option that finishes an accepted match with a space.
