The proposal aims to upgrade Polkadot’s runtime to [v9300](https://github.com/paritytech/polkadot/releases/tag/v0.9.30). More information about the release can be found on the link in this post. As the external queue can only hold one proposal at a time, yesterday's [motion 286](https://polkadot.polkassembly.io/motion/286), removing the limits on members in nomination pools, deleted previously approved [motion 285](https://polkadot.polkassembly.io/motion/285) aiming to upgrade Polkadot's runtime. This new proposal replaces motion 285.

Proposal hash: `0xf1eeaa09f9a85633cf7f1fa588bf3247a58acf9f4cb3e8e12350833c595bc7d3`

You can review the hash and changes in the release notes and use SRTool to verify proposal hash - make sure to vote at your convenience! This proposal is submitted as an **external motion**: meaning after Council vote, the community will need to vote on the proposal in referenda queue. 

Set the new runtime code.

# <weight>
- `O(C + S)` where `C` length of `code` and `S` complexity of `can_set_code`
- 1 call to `can_set_code`: `O(S)` (calls `sp_io::misc::runtime_version` which is
  expensive).
- 1 storage write (codec `O(C)`).
- 1 digest item.
- 1 event.
The weight of this function is dependent on the runtime, but generally this is very
expensive. We will treat this as a full block.
# </weight>

- There is a proposal to upgrade Polkadot's runtime.
- The proposal replaces a previous motion that aimed to upgrade Polkadot's runtime.
- There are different changes and audits being done to the runtime.
- The proposal has a specific hash that can be reviewed.
- The community will need to vote on the proposal in the referenda queue.
