# Upgrade the Governance Canister to Commit 43723a2

__Proposer__: jason.zhu at dfinity.org

__Source code__: [43723a278465c0725b7cc2e3374f7c8545395cb6][new-commit]

[new-commit]: https://github.com/dfinity/ic/tree/43723a278465c0725b7cc2e3374f7c8545395cb6


## Features & Fixes

###  Added


* Enabled BlessAlternativeGuestOsVersion, which would generally be used to
  recover a subnet where a) orchestrator is not working for whatever reason, and
  b) SEV is enabled and/or there is no DFINITY node in the subnet.

* Proposal types for taking and loading a snapshot of a canister controlled by the NNS Root canister.

* Enabled self-describing proposals:

- A `self_describing_action` field is added to `Proposal` when it's created, to describe the
  proposal in a generic way, which can be parsed by a client without having to constantly adapt to
  the new proposal types.
- APIs like `get_proposal_info`, `list_proposals` and `get_pending_proposals` returns this new field
  (`list_proposals` and `get_pending_proposals` require passing an additional boolean flag in order
  to get this new behavior).
- This field is backfilled for existing proposals.

###  Changed

- Change the minimum requirement for maturity disbursement from ~1.06 to 1 (ICP equivalent).

## Verification

See the general instructions on [how to verify] proposals like this. A "quick
start" guide is provided here.

[how to verify]: https://github.com/dfinity/ic/tree/43723a278465c0725b7cc2e3374f7c8545395cb6/rs/nervous_system/docs/proposal_verification.md


### WASM Verification

See ["Building the code"][prereqs] for prerequisites.

[prereqs]: https://github.com/dfinity/ic/tree/43723a278465c0725b7cc2e3374f7c8545395cb6/README.adoc#building-the-code

```
# 1. Get a copy of the code.
git clone git@github.com:dfinity/ic.git
cd ic
# Or, if you already have a copy of the ic repo,
git fetch
git checkout 43723a278465c0725b7cc2e3374f7c8545395cb6

# 2. Build canisters.
./ci/container/build-ic.sh -c

# 3. Fingerprint the result.
sha256sum ./artifacts/canisters/governance-canister.wasm.gz
```

This should match `wasm_module_hash` field of this proposal.
