guideUpdate to CKEditor 5 v38.0.0

When updating your CKEditor 5 installation, make sure all the packages are the same version to avoid errors.

For custom builds, you may try removing the package-lock.json or yarn.lock files (if applicable) and reinstalling all packages before rebuilding the editor. For best results, make sure you use the most recent package versions.

For the entire list of changes introduced in version 38.0.0, see the release notes for CKEditor 5 v38.0.0.

Listed below are the most important changes that require your attention when upgrading to CKEditor 5 v38.0.0.

Starting from version 38.0.0, all open source installations of CKEditor 5 will include a small “Powered by CKEditor” logo in the bottom-right corner of the editing area. This logo is designed to raise awareness of the CKEditor brand and will link to the CKEditor website.

If you have a commercial license, you can hide the logo by adding config.licenseKey to your configuration. If you already use pagination, productivity pack, or non-real-time collaboration features, you don’t need to take any action as you should already have config.licenseKey in place. The logo will not be visible in your editor.

We have prepared a detailed Managing the “Powered by CKEditor” logo guide to help everyone through the transition and explain any concerns.

# Introduction of color pickers to font color and font background color features

Starting with v38.0.0, the user interface of the font color and font background color features will display a color picker. The new feature is enabled by default. It supplements existing color palettes to improve the editing experience and boost the creativity of content authors.

However, we are aware that the freedom to choose any color may introduce noise and inconsistency to the content of some integrations with already configured palettes. If this is your case, you can disable color pickers in both font color and font background color features by setting the colorPicker option in their respective configurations to false:

    .create( document.querySelector( '#editor' ), {
        fontColor: {
            // Disable the color picker for the font color feature.
            colorPicker: false
        fontBackgroundColor: {
            // Disable the color picker for the font background color feature.
            colorPicker: false
        toolbar: [
            'heading', 'bulletedList', 'numberedList', 'fontColor', 'fontBackgroundColor', 'undo', 'redo'
    } )
    .then( /* ... */ )
    .catch( /* ... */ );
