Thanks to everyone who joined our COIN-OR AGM today.

CyLP has a new release that supports Numpy 2 for those who were waiting for that! As always, there are binary wheels for all platforms, thanks to #cibuildwheel! https://t.co/ITneiqrmNt

I'm really excited to announce version 1.2.0 of MibS, our solver for bilevel mixed integer linear optimization. There are a lot of of improvements, especially to usability and out-of-the-box performance. https://t.co/4TjXSF2GfY.

How can we best continue to support the open-source OR software community?

[Matthew Saltzman @SaltzmanMJ]

Thinkinh about how to fix science's code problem. What @coin_or has been thinking about for 20+ years regarding code in #orms. It's a difficult challenge.

Thanks to the help of @mkoeppe_math, CyLP now has a much improved build process, plus a Github Action that builds binary wheels bundling required libraries for all platforms using the amazing cibuildwheels 🚀. No need to separately install Cbc! https://t.co/qM77G0dio6

[COIN-OR Foundation @coin_or]

Github now supports organization-wide Discussions! This supplants the few remaining mailing lists we had: the venerable coin-discuss and coin-announce, which served us well for 20+ years but have been showing their age. On to greener pastures! https://t.co/xPFnnN1L4J
