From now, you need to explicitely add sitemap=True if you want your controller
into the sitemap.
It's the default value, but if you forgot it, it will raise a Warning on runbot.
It will avoid wrong controller in sitemap and duplicate (empty) content.
From now, if your model contains a field website_id, the modelConverter for
sitemap will automatically add the domain:
"[('website_id', 'in', (False, current_website_id))]"
It avoid redundant declaration and ugly url in redirect/rewrite view.
Migration: need to remove it from url_from in website.rewrite
