Full Changelog: v4.1.20...v4.1.21

The Breton far is a rather dense cake from Brittany, a distant cousin of the flan pâtissier or the clafoutis according to the variants. It is called in Breton farz forn (farz fourn in Leonard country) which means: far au four. The most famous recipe is the one with prunes, although traditionally the far doesn't include them.
