bpo-24937: Replace the extension module porting HOWTO by links to external projects by encukou · Pull Request #9317 · python/cpython (original) (raw)
I've talked with Benjamin, and he's OK with just removing the "Porting Extension Modules to Python 3" HOWTO, and replacing it by links to external guides that do a much better job at documenting this.
Also, Python 2.6 and 3.0 is EOL; it should be fine to scrub capsulethunk.
