This proposal aims upgrade the Polkadot network to runtime [v9420](https://github.com/paritytech/polkadot/releases/tag/v0.9.42): the specific details on this upgrade please check the release notes. This runtime contains the changes from v9370 to v9420. Please note there are 4 runtime migrations for the Relay Chain in this release (details below). In addition to the migrations mentioned above, all the migrations included in runtimes since v9380 have been included in this release, allowing to jump over a few runtimes.

- Preimage is submitted.

### Relay Chain

Among other things, this proposal includes the inclusion of OpenGov on Polkadot. Note that, in order for OpenGov to be fully operational, [the proposal upgrading collectives parachain](https://polkadot.polkassembly.io/motion/403) needs to be approved and enacted (this is ongoing). If this happens, Fellowship will be created in the Collectives parachain. The Technical Fellowship is an integral part of OpenGov model.

### System Parachain Runtimes

This Polkadot system parachain upgrade includes changes since v9370, which has several major updates. For one, it includes XCM v3.

On Statemint, this does not include NFT 2.0 or Foreign Assets as the Statemine release does, although with the audits completed these will be in an upcoming release. It does include the new runtime API to [query account balances](https://github.com/paritytech/cumulus/pull/2455), which will return all the fungible assets (under the Balances pallet and both instances of the Assets pallet) that an account owns in a single RPC call. This should be particularly useful for front end developers.

### External Motion

Please note this proposal is submitted as an external motion: meaning after/if Council approves, this submission will be up for vote in referenda queue for the community to have the final decision. It is a general expectation, given the size of the upgrade, for the community to vote on this for a complete launch period (28 days). 

Make sure to vote at your convenience!
