Had a great time hacking on @aiohttp.org (@bdraco.org and @webknjaz.me).

Got a few new contributors and sirosen lurking in, as well as achimnol the aiosignal maintainer.

Looking forward to gathering again tomorrow!

👋 @bdraco.org and @webknjaz.me are going to be running a @pycon.us sprint next week.

Come by and say hi!

The sprint link is us.pycon.org/2025/events/....

We've also started a GH project to organize possible vectors or work. But that's not restrictive.
