This proposal aims upgrade Kusama relay chain to runtime v9420 and Kusama System Parachains (Statemint/Collectives) to runtime v9420: the specific details on this upgrade please check the release notes. This release contains the changes from v0.9.41 to v0.9.42. Please note there are 4 runtime migrations for relay chain on this release (details below), and 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.

System parachains Runtime
This Kusama system parachains upgrade includes changes since v9382. Most notably, this includes the new NFT 2.0 pallet (pallet-nft) on Statemine. This includes a number of new functionalities like smart attributes. More features can be found in the primary tracking issue. As the audit has been completed, this will be coming soon to Statemint.
This release also includes a new instance of the Assets pallet, called ForeignAssets. Foreign Assets uses a MultiLocation as an asset class identifier and allows other parachains (and eventually bridges) to represent their native assets directly on Statemine. For example, the asset ID of the native asset of Parachain 9000 would be { parents: 1, interior: X1(Parachain(9000)) }. The original instance of the Assets pallet remains, and is often referred to as the “Trust Backed” Assets pallet, denoting the fact that they are administered by an account that one trusts to have some off-chain, corresponding asset.
Finally, there is a new runtime API to query account balances, 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.
