Why isn't the ISO 20022 repository snapshot more up-to-date?

The snapshot used by this tool is always the latest one made publicly available on the ISO 20022 e-Repository. Each new release requires adaptation and testing before it can be integrated, but you can expect any newly published version to be available within days, not weeks. The release schedule is controlled entirely by the ISO 20022 working groups and administration — we integrate new snapshots as soon as they’re released.
