And if it's not fixed in 4.0 break, when will it be? You want to break compatibility after 4.0?<br><br><div class="gmail_quote">Le 17 août 2018 14:52:21 GMT+03:00, Thomas Guillem <thomas@gllm.fr> a écrit :<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
