Private alpha
This release is for invited testers. It is early software and is not ready for production use.
Plan for bugs, breaking changes, and possible data loss. Keep a separate backup of important data and test that you can restore it.
If you have an invitation, use the install command supplied with it. That command selects a specific release and checks the downloaded script against a pinned digest.
There is no public one-line installer for the alpha. Do not install from an unverified command or link.
