Valtteri Bottas has maintained a "very good working relationship" with Williams despite months of rumours linking him to Ferrari.
The Finn's future was the hot topic of the silly season with speculation that Kimi Raikkonen was on his way out of Ferrari and Bottas on his way in.
In the end, the Scuderia opted to retain their Finn while Williams kept Bottas.
"Before I arrived at Monza, it was announced that I extended my contract with Williams for another year," Bottas said in his latest blog.
"It's good to have the new contract signed and know what I'm going to be doing next year. At least there's no more speculation and the team and myself can focus on the job of making the car quicker and delivering the results.
"We can now start working on the development of next year's car and share all the information needed without any doubts."
The 26-year-old added that the speculation had not harmed his relationship with Williams despite technical boss Pat Symonds saying it would "inevitably" do so.
Bottas continued: "Our relationship wasn't damaged at all, but that can happen if people think you are looking to leave a team.
"No damage has been done and I'm very happy to stay with the team, and they are very happy to keep me as well. I get along with every single person at Williams and we have developed a very good working relationship over the years.
"I think this is the best place for me at the moment and continuity will be good for us, particularly as I'll have the same team mate in Felipe Massa. Together we have a good baseline and we can work together to get even better results."
