Upgrading CKEditor

This article describes the steps you need to take when you want to upgrade your CKEditor 4.x installation to the latest version.

The latest CKEditor is always the greatest CKEditor. New releases add cool new features, support for the latest browser versions, and bug fixes. The changelog is published here and you can also learn about new releases by following our blog, Facebook, Google+, or Twitter pages.

To upgrade CKEditor, proceed as follows:

  1. Rename your existing editor folder to a backup folder, for example ckeditor_old.
  2. Download the latest version from the official CKEditor Download site.
    • If you are using one of the pre-defined presets like Standard or Full, download the same one.
    • If you created a custom CKEditor build, you have a few options, as described in your backed-up build-config.js file.
      • You can use the unique link to download the updated version of your custom build using the latest editor release.
      • You can use the unique link to CKBuilder pre-loaded with your custom build configuration and using the latest editor release.
      • You can go to the CKBuilder site and click the Upload build-config.js button. Select your backed-up custom build configuration file and download the updated build containing the latest versions of all selected plugins.
  3. Extract (decompress) the downloaded archive to the original editor directory, for example ckeditor.
  4. Copy all configuration files that you have changed from the backup directory to their corresponding positions in the new directory. These could include (but are not limited to) the following files:
    • config.js
    • contents.css
    • styles.js
    • custom template files
