Wrote a book chapter
Chapter 11 of Publishing Python Packages, the latest and final, is now drafted and edited! The book now goes through a final review with the cohort, whose feedback after chapter 7 was overwhelmingly positive. I hope despite the slowing pace toward the finish line I've managed to keep up the quality! Feedback from an early reviewer on chapter 11 said:

Please congratulate the author for me. It was a pleasure to read his fine work.

A big thanks to everyone who has been a part of the early access program so far, and to the Python community for the huge advances made in the past few years to make things great.
