### IMPORTANT NOTE ON THIS UPGRADE:

Assuming Referendum 96 passes, Polkadot will upgrade to runtime v9340 on Saturday 14 Jan. This will have several effects: **please read below!**

First, any outstanding multisig calls (ones where one signatory has signed, but not the threshold) will not be able to execute. Please either finish your multisig calls before this upgrade, or wait until after it is completed. [https://github.com/paritytech/substrate/pull/12072](https://github.com/paritytech/substrate/pull/12072).

All preimages and the dispatch queue will be cleared. Any Referenda already passed but not enacted will thus not execute. If the Referendum is ongoing, the preimage can be re-uploaded after the upgrade. [https://github.com/paritytech/substrate/pull/11649](https://github.com/paritytech/substrate/pull/11649).
