The license management for CKEditor 5 has been simplified by extracting the licenseKey configuration into an extra sidecar file ckeditor5License.ts .

The existing CKEditor 5 instance factories ( ckeditorDefault.ts , ckeditorHtmlViewer and ckeditorSlim.ts ) have been adapted to use this key via deconstruction pattern:

return ClassicEditor.create(domElement, {
    ...ckeditor5License, // new, was licenseKey: "" before
    placeholder: localize('Type your text here...', language),

In addition to this change, the default license key is now an OEM license key, shipped with @coremedia/ckeditor5-coremedia-oem-activation , rather than an empty one.

This OEM key must not be used outside CMCC, but may be reused for your custom CKEditor 5 instance factories. To enable premium CKEditor 5 features, you must purchase your own license.
