This is a referendum to upgrade Polkadot to v1.2.5. See the [Fellowship release notes](https://github.com/polkadot-fellows/runtimes/releases/tag/v1.2.5) for more details.

Of special note is the inclusion of the new `CheckMetadataHash` extension. This is a breaking change for transaction encoding on all chains. Please update wallets and applications accordingly.

Enactment is set for block [21,455,000](https://polkadot.subscan.io/block/21455000), which should land on 1 July.

See [`Pallet::dispatch_whitelisted_call_with_preimage`].
