A few weeks ago we introduced a new feature: if you included a URL reference in a card’s details, attachments or chat, we would fetch that Web page’s title and show that, instead of just the “raw URL”.
This turned out to be a really helpful feature, and so we are expanding it in our next version by adding logic to handle a wider variety of URLs: the new logic should make it easier to have smart references to URLs show up in your cards even when these URLs are pointing to obscure Web sites, Intranet sites, etc.
