A new release of Xenforo that was just installed on our site has some already known bugs.
One is that the image editing tool that pops up underneath the image when you insert the image, and which allows you to resize images by pixel size and other things, seems to have disappeared. You can still resize the image by resizing the . . . box around the embedded image.
Annoying, but Xenforo has confirmed they will fix the bug at some point.
