nukeSEO.com released nukeWYSIWYG™ 2.6.4 featuring FCKeditor. This update includes several important new and improved features:

• File manager requires Nuke admin authentication (identified by S Electric)
• FCKeditor 2.6.4 with new web-based spell checker
• Browser-specific and compliance fixes

Please note that the file manager has always validated uploads to prevent files that can be used to cause harm to a site (e.g. executable files like .js and .php, as well as scripts renamed to be images).

RavenNuke™ users: The admin authentication change is already implemented in RavenNuke™ 2.30.02 available on this site. We are considering FCKeditor 2.6.4, CKeditor and other editors for future releases of RavenNuke™

• Upgrade for those currently using nukeWYSIWYG™ 2.6.3 - available here
