Congratulations to the Spack team on reaching this significant milestone!
💥Spack v1.0 is out!💥
This is a huge milestone. We reworked the core to add compiler dependencies, and we're introducing a stable package API.
🚀1.0 also adds concurrent builds, better includes, and much more -- read it all in the release notes!

This is excellent news! Spack is an incredible tool within the HPC software management space, but I also use it on my own Linux machine to manage builds and environments. Like conda for compiled code.
