Introducing FrontierCode: a coding eval that raises the bar for difficulty & quality. Each task took 40 hrs of work by leading open-source maintainers. Models write sloppy code that works but isn’t maintainable. Our eval is first to measure: would you actually merge this code?

Since I started contributing to Celery, improving the QA was one of my highest priorities, leading to the creation of pytest-celery v1.0.0 to support enterprise-grade QA requirements. After endless nights of fine-tuning, bug fixing, and ensuring that we're g2g, I had to face the hard truth of our CI limitations. What my laptop did in 10m, took our CI about an hour, and that was just a simple PR.. Blacksmith has completely changed the game by unleashing the full potential of our new QA infrastructure, virtually unlimited concurrent PRs, NO DOWNSIDES, and I still can't believe it was 1-click away. Thank you for sharing our story @useblacksmith. Appreciation > 9000 🔥

Fun fact: When our CI performance quadrupled, our contribution rate did too. Huge thanks to @useblacksmith for powering our CI! The impact was real.

Celery v5.5.3 and Kombu v5.5.4 are now released! 🎉 Key highlights: ✅ Quorum Queues bug fixes! ✅ Better dependency alignment between Celery & Kombu! ✅ Improved test coverage and documentation enhancements! ✅ Enabled DeepWiki auto-refresh! Kombu Changelog: github.com/celery/kombu/rele… Celery Changelog: github.com/celery/celery/rel…

One of my personal objectives for the @CeleryOrg this year is improving customer support at scale. I've explored numerous AI solutions, but none have had such a massive impact as this one. My CeleryGPT dream is slowly taking shape, step by step.. What a time to be alive 💫
