Changement profond de l'index. Utilisation des templates. Dual Blog utilise maintenant intimement la libraire de templates que l'on peut trouver sur http://hg.defr.org/defr/templates, ce qui permet d'eviter de mixer du code PHP avec du HTML. Accessoirement, on est aussi assurer d'avoir du XML valide, puisque c'est l'API DOM qui est utilisée pour générer la sortie.
