broken link on page "Migrating from GTK+ 2.x to GTK+ 3"

Hello gnome-web-list

On the page: 
https://developer.gnome.org/gtk3/stable/gtk-migrating-2-to-3.html ,
in the section "Do not use deprecated symbols", the link on the word "index" in the following sentence:

The API reference for GTK+ 2 also includes an index of all deprecated symbols. 

 - does not resolve to the expected Web page:

https://developer.gnome.org/gtk/stable/2.24/api-index-deprecated.html

 - but is redirected to

https://developer.gnome.org/gtk3/stable/2.24/api-index-deprecated.html

 - which is a 404. The handler says:

"Not Found
The requested URL /gtk3/stable/2.24/api-index-deprecated.html was not found on this server.
Apache/2.2.15 (Red Hat) Server at developer.gnome.org Port 80"

Thank you for your time
