Welcome to the past! 👻
Unfortunately, FCKeditor is no longer maintained. RIP ❤️
Or, you can discover CKEditor 4, which is an enterprise-grade WYSIWYG editor with countless features and wide browser compatibility including the legacy ones.
This is mainly a "stabilization" release of version 2.4. The Enter Key Handler has now a consistent behavior and many small bugs have also been fixed. Upgrade from version 2.4 is highly recommended.
We thank our great collaborators community, which helped us again to release another great version of FCKeditor.
