It's weird it doesn't say it in French but we have that at the same place in the Note.

[dev1288] Le bouton permettant de changer l’aire d’effet des sorts a été supprimé.
En conséquence, la commande texte /areaofeffect a également été supprimée.

It says:

The button that allows you to change the area of effect of spells has been removed.
Thus, the text command /areaofeffect has been removed too.

We have that info and you have the Protect/Shell info. The Notes are really different from country to country. Weird.
