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

On Collectives specifically, this update includes the [Technical Fellowship](https://github.com/paritytech/cumulus/pull/2186). It corresponds to the launch of Open Gov on Polkadot, which is included in the Relay Chain runtime. The Fellowship will manage its membership and referenda voting on the Collectives chain, while sending its decisions (e.g. to whitelist a call for the `WhitelistedCaller` track) in an XCM message to the Relay Chain.
