The following table lists the database versions with brief descriptions of each.
The "TC Version" column gives the Taskcluster version in which this database version was introduced. The compatibility invariant dictates that the DB version is compatible with all code from the previous major version through this one. For example, if DB version 0123 was introduced in Taskcluster version v59.7.1, then it is compatible with all Taskcluster versions v58.0.0 through v59.7.1. If this invariant is violated, it must be indicated clearly in the changelog.
