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.

And there’s soooooo much wasted disk space installing every package 9001 times across venvs. One of the things I like about spack is that there is a global install cache and then it just assembles a local view with links.
