Can we have some scary labels to ensure this PR is getting attentions by parachain teams? It is a breaking change and will impact scripts related to runtime upgrade. |

Adds checks to ensure that the spec version is increasing and that the spec name is the same. This will prevent accidentally upgrading a parachain to a different runtime.
Migration
Although this changes storage, I did not increase the storage version or provide a migration. The reason is that the upgrade itself will
killthe affected storage item, and the next time an upgrade is authorized, the new type will be written. But this will break any front ends that show authorized upgrades, so let me know if I should bump the storage version for this.Transaction Version
Unfortunately breaks it, although it's a Root call. Could also add a new function
authorize_upgrade_without_checksas an alternative.
