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! github.com/orgs/coin-or/d…

Thanks to the help of Matthias Köppe, 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! github.com/coin-or/CyLP/r…
