Please note that CKEditor 4 reached its End of Life (EOL) in June 2023. From then on, it receives no more updates, new features, bug fixes, and most importantly, security patches.
If you have an active CKEditor 4 subscription and need help, you can contact our support team. If you are not ready to migrate yet, for a limited time we are offering a paid Extended Support Model that will protect you against security vulnerabilities and/or breaking third-party API changes.
The CKEditor 4 core team doesn’t work on MediaWiki integrations. If you need to use any other custom format like Wiki markup, you would need to adjust the output format of the editor. See our BBCode plugin sample which is an example of CKEditor 4 output customisation.
