A few weeks ago (before a short vacation) marked my Informational PEP 630 as Active. I encourage anyone who uses Python’s C-API to read it. It includes a practical introduction to the “new” module-related C-API.
The new API is not complete for all use cases (see Open Issues), so I am not trying to integrate the text into Python’s documentation, but it should be good for early adopters (including Python’s stdlib) and API critics. In fact, the PEP includes most answers I gave to these people :)
I should also mention that the PEP is not about all recent activity around the C-API – for example the effort to eventually eliminate all static types is orthogonal.
Personally, the PEP summarizes my last 5 years of contributing to CPython. Thank to everyone who helped, ans especially @ncoghlan who got me started, way back in 2015.
