**EXTRA NOTE ON THE REJECTION SUGGESTION:**
###
While the proposal moved to external queue to be voted by the community after Council approval, the Acala team noticed an issue with the runtime release: The XCM weight isn't benchmarked for Polkadot and the base weight is used, which assumes each XCM instruction takes 64k proof size. For XCM message with 1D weight, a default proof size of 64k is used. This means xcm buy weight with limited 1D weight will fail on [this line](https://github.com/paritytech/polkadot/blob/f1a45b39db6dbb7610c80b82d7cfca45a807619d/xcm/xcm-builder/src/barriers.rs#L96): this only impacts XCM V2 instructions using limited weight. Unlimited weight is fine.

The teams are now studying on what appropriate value should be put into the proof size weight component for BaseXcmWeight: once this is decided, a new release will be cut and the proposal will be submitted for vote again. 

For now, this proposal can be cancelled/rejected.

This proposal aims upgrade Polkadot relay chain to runtime [v9381](https://github.com/paritytech/polkadot/releases/tag/v0.9.38-rc12) and Polkadot System Parachains (Statemint/Collectives) to runtime [v9382](https://github.com/paritytech/cumulus/releases/tag/parachains-v9382): the specific details on this upgrade please check the release notes. This release contains the changes from v0.9.39-1 to v0.9.38-rc12. **Among other things, this upgrade includes XCMv3 on Polkadot**. Please note that two calls for the System parachains upgrade are `xcm.send` extrinsics that send `authorize_upgrade` messages to Statemint and the Collectives, while for the relay chain upgrade is `setCode`

This proposal is submitted as an external motion: meaning if/after Council approves the motion, the community will have the final say in referenda queue.  

Make sure to vote at your convenience!

Schedule a majority-carries referendum to be tabled next once it is legal to schedule
an external referendum.

The dispatch of this call must be `ExternalMajorityOrigin`.

- `proposal_hash`: The preimage hash of the proposal.

Unlike `external_propose`, blacklisting has no effect on this and it may replace a
pre-scheduled `external_propose` call.

Weight: `O(1)`

Send a batch of dispatch calls.
Unlike `batch`, it allows errors and won't interrupt.

May be called from any origin except `None`.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then the calls are dispatch without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).

# <weight>
- Complexity: O(C) where C is the number of calls to be batched.

:
- Proposal aims to upgrade Polkadot relay chain to runtime v9381 and Polkadot System Parachains (Statemint/Collectives) to runtime v9382
- XCMv3 is included for Polkadot in this upgrade
- Preimage can be reviewed on polkadot.js.org
- After Council approval, this proposal will move to voting on referenda queue
