Recapping all of the additional news and notes from Hockenheim on Friday, wuqian0821.com F1 Editor Luke Smith brings you his paddock notebook.

- The FIA confirmed Daniel Ricciardo's drop to the back of the grid for Sunday's race following Red Bull's changes to his power unit. Ricciardo's car has been fitted with a new MGU-K, control electronics and energy store for the race wꦑeekend, exceeding the permitted number of comಞponents for the season on each element. With this penalty in mind, Ricciardo opted to focus solely on long runs through FP2, finishing the session 13th.

- Other power unit changes came for all of the Ferrari-powered drivers, all of whom have taken a fresh MGU-K, while Sebastian Vettel, Kimi Raikkonen and Max Verstappe🌃n have also taken a new energy store. All of these changes are within the regulations, so no added penalties will be dished out.

- By way of new gearboxes, Valtteri Bottas, Esteban Ocon, Max Verstappen and Marcus Ericsson all have new units for the event. Bottas and Ocon take fresh gearboxes after making their previous o🥃nes last six events, while Verstappen and Ericsson failed to finish the last race, meaning they are permitted to make a free change.

- Pierre Gasly revealed his move on Sergio Perez in the British Grand Prix was discussed at length during the drivers' briefing, with "everyone" agrꦺeeing with his view that it was a racin🌱g incident. Gasly said he hoped it would set a precedent for what should be classed as a racing incident in the future.

- Despite the high-speed first and second sectors at Hockenheim, Red Bull was able to charge to the top of the timesheets in both FP1 and FP2♒ on Friday via Daniel Ricciardo and Max Ver🥂stappen in the respective sessions. Lewis Hamilton finished a narrow second for Mercedes both times around, with the Ferraris of Sebastian Vettel and Kimi Raikkonen remaining within striking distance.

- High temperatures led to high levels of degradation throughout practiceജ, especially on the Ultrasof🧸t tyre. However, temperatures are not expected to reach the same level this weekend, while tomorrow's qualifying could even be wet, judging by some forecasts.

- While Sunday's race may reportedly be a sell-out, the grandstands were noticeably bare for much of Friday🎉's running. Hockenheim will deliver its attendance figures post-race on🔯 Sunday.

- The big news this morning was Valtteri Bottas' contract extension with Mercedes for 2019, with an o🐻ption in place for 2020. It came♈ less than 24 hours after teammate Lewis Hamilton had been confirmed at Mercedes for the next two seasons, making the team the first to confirm its full line-up for next season.

- The other news brea🍎king ahead of FP1 was the FIA's invitation to tender for the 2020 to 2023 tyre supply, with confirmation of a ban on tyre blankets and a switch to 18-inch wheels from 2021 also being confirmed. This means that if a rival tyre manufacturer were to replace Pirelli, it would have to produce two different sizes of wheels in the space of two years.
