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!

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.
