https://github.com/ipfs/fs-repo-migrations/releases/tag/fs-repo-12-to-13%2Fv1.0.0 This will be used to upgrade the Kubo repo when updating to Kubo 0.18.
Two old migrations were broken since Go 1.16 was removed from Nixpkgs. Upstream is not interested in fixing the migrations to work with newer Go versions: https://github.com/ipfs/fs-repo-migrations/pull/163#issuecomment-1397311134.
Go-IPFS was renamed to Kubo in version 0.14.0, see https://github.com/ipfs/kubo/issues/8959.
