This version of the Core introduces the new HTML editor. It is being introduced in this version of the Core and will be showing up in your modules soon. The new editor offers all of the features that you love as well as some new features. These new features include, but are not limited to, the ability to edit images, browse images more efficiently and specify font sizes more accurately.
Also in this version of the Core, we are introducing customizable admin menus. You can now hide some of those default admin menus that you don't use and even create new ones that might be more helpful to you.
Finally, we also added a new role to the Core that will allow you to approve members for commenting. Any member with the Approved Commenter role will have their comments automatically post to the site immediately.
