If the recently published draft 2019 Formula 1 calendar has a familiar look to it, that should be no surprise, given that it features the same 21 races as this year's version.
There are no new events, as Miami's planned debut has been delayed until 2020. But all the other current races will continue, including - thanks to a last minute one-year deal subsidised in part by Mercedes - the German Grand Prix at Hockenheim.
Look a little closer and you will see some subtle changes. There's no repeat of the European triple header, as there is a free weekend between Austria and Britain. Meanwhile, several of the back-to-back flyaway pairings have been adjusted. Bahrain and China are now on their own instead of being paired, Russia follows Singapore instead of preceding Japan, and Mexico and the USA have swapped places.
