+### Redrawing semantics of routing
+
+By default, changing routes causes templates to be re-rendered from scratch. This behavior can be changed either via the [retain flag in a config's context object](mithril.md#persisting-dom-elements-across-route-changes), or the [`m.redraw.strategy("diff")` hint](mithril.redraw.md#changing-redraw-strategy).
