- A result of <T> can implement the new `hero.PreflightResult` interface which contains a single method of `Preflight(iris.Context) error`. If this method exists on a custom struct value which is returned from a handler then it will fire that `Preflight` first and if not errored then it will cotninue by sending the struct value as JSON(by-default) response body.
- `ctx.JSON, JSONP, XML`: if `iris.WithOptimizations` is NOT passed on `app.Run/Listen` then the indentation defaults to `" "` (two spaces) otherwise it is empty or the provided value.
- `ctx.JSON, JSONP, XML`: if `iris.WithOptimizations` is NOT passed on `app.Run/Listen` then the indentation defaults to `" "` (four spaces) and `" "` respectfully otherwise it is empty or the provided value.
- Hero Handlers (and `app.ConfigureContainer().Handle`) do not have to require `iris.Context` just to call `ctx.Next()` anymore, this is done automatically now.
