I’m using this Extra with a custom external .config.json file which until recently was working fine. However, with TinyMCE 6 the devs have changed the naming convention of several features. It’s an easy fix, just update the names in the .config file. For example, rel_list is now link_rel_list.
Most of the new names work without a hitch but I’m finding that a couple of the link-related ones don’t, such as the rel example which was working with TinyMCE 5. Has anyone else noticed this? I don’t know if it’s a problem with the Extra or TinyMCE itself.
