BBC Latest News - Doctor Who - The 2017 Series… Returning Writers, Cast Updates and More!:

Episode 9 of Doctor Who’s 2017 series is written by Rona Munro, author of the very last Doctor Who story of the show’s original 26-year run – the seminal and highly acclaimed 1989 Seventh Doctor adventure Survival.

Personally, I'd like to see even more Munros writing Doctor Who.
