Expand description

Builtin schema migrations required to upgrade to the current build version.

Migration steps for old versions must be retained around according to the upgrade policy. For example, if we support upgrading one major version at a time, the release of version N.0.0 can delete all migration steps with versions before (N-1).0.0.

Smallest supported version: 0.147.0
