That's a new feature and is explained in the upgrading documentation. You can change settings to get back the old URL transformation scheme (urlalias_compat) and you can even define your own.

By the way, i've got a question about url translator in the demo ezwebin.
- You have a product by default in english (url_en = my-product)
- Then you translate it in french (url_fr = mon-produit).
- And now, from the french site you try to go directly on the italian site by changing only the siteaccess (languages on the left top) => Error, cause the uri "mon-produit" is not defined in italian.
So, i wondered if there was new api or attributes to get the default uri, or find the translated uri ?
