We had 18 merged pull requests and 13 additional commits - and there's a beautiful story here about community…
So picture this: it's like the entire Python core development team decided to have a spring cleaning day, but instead of organizing closets, they're hunting down memory leaks and making Python more robust for all of us. And leading this charge is Pieter Eendebak, who submitted not one, not two, but three separate…
Let's dive into what happened. Pieter's first PR tackled reference leaks in the Objects directory, touching seven different files including the curses module, binascii, and Unicode handling. Then they followed up with another PR addressing leaks in both Objects and Modules - and here's the cool part - they mentioned…
