This is the first beta release of the next generation of the Buf CLI. This beta release is being used by some of our customers to ensure we've kept compatibility, and to try some of its new features. Don't worry - the next generation of the buf CLI continues to be v1, and is completely backwards-compatible - all of your workflows will continue to work. Buf is enterprise-grade software, and we want you to be minimally impacted.
There's some exciting improvements coming in the next generation of the buf CLI, and we look forward to sharing it more widely in the coming weeks. If you'd like to be part of the private beta, email us with the subject line "Beta" and we'll be happy to talk - we'll add more users as we have capacity. While you are free to give this beta release a spin without being added to our private beta, we wouldn't recommend using it outside of our private beta just yet!
