     Origin not being able to pay the existential deposit (ED) for a new account is now `StorageDepositNotEnoughFunds` and traps the caller rather then being a `TransferFailed` return code. Important since we are hiding the ED from contracts, so it should also not be an error code that must be handled.
   - [#8314](https://github.com/paritytech/polkadot-sdk/pull/8314): Add RPCs in the statement store to get the statements and not just the statement data.
     In statement-store, statements can contain a proof with the signature of the statement. This proof is useful to assert that the statement comes from the expected account. This proof also signs for all the statement's fields, which can also be useful information for the receiver.

+  - [#7953](https://github.com/paritytech/polkadot-sdk/pull/7953): Add deposit for setting session keys

 - Add foreign-consensus cousin Asset Hub as trusted aliaser to allow XCMv5 origin preservation for foreign-consensus parachains [polkadot-fellows/runtimes/pull/794](https://github.com/polkadot-fellows/runtimes/pull/794))
 - Configure block providers for pallets requiring block context ([polkadot-fellows/runtimes/pull/813](https://github.com/polkadot-fellows/runtimes/pull/813)):
   - vesting: keep using Relay Chain block provider
