CKEditor5 has been updated to version 45.2.0 and comes with updated versions of CoreMedia's CKEditor5 plugins. The update includes 2 major changes:

If you have customized the link targets for the link balloon, you will now have to add those targets to the link.toolbar configuration. Please have a look at the corresponding documentation.

Migration Path

Previously you would have configured the link targets via this configuration:

//...
link {
  //...
  targets: [
    "_self",
    {
      name: "_parent",
      icon: parentIcon,
    },
  ]
}

Now, the new toolbar configuration handles which targets are displayed inside the link balloon. You will still need to define custom targets in targets to remove the default targets (“_self”, “_new”, “_other”, “_top”) and simply add them to the toolbar. Please note, that you will also need to add the buttons to display, edit or unlink the link here as well:

//...
link {
  //...
  toolbar: ["linkPreview", "editLink", "|", "_self", "_parent", "|", "unlink"],
  targets: [
    {
      name: "_parent",
      icon: parentIcon,
    },
  ]
}

The default toolbar looks like this. Please feel free to reconfigure it in ckeditorDefault.ts if you previously changed the link targets:

["linkPreview", "editLink", "|", "_self", "_blank", "_embed", "_other", "|", "unlink"]
