# Upgrade the Governance Canister to Commit 80d2c37

__Proposer__: jason.zhu at dfinity.org

__Source code__: [80d2c37e0be4244e1090388ea2039138dc49c881][new-commit]

[new-commit]: https://github.com/dfinity/ic/tree/80d2c37e0be4244e1090388ea2039138dc49c881

## Urgent Release

This is to fix a performance degradation introduced by the previous release. Therefore DFINITY intends to vote on it sooner than usual. 

Because we do not want to introduce more changes than what's necessary, this release is not built from master, but a branch based on the previous release (proposal 134193) with only the bug fix applied on top of it.

## New Commits

## 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/80d2c37e0be4244e1090388ea2039138dc49c881/rs/nervous_system/docs/proposal_verification.md


### WASM Verification

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

[prereqs]: https://github.com/dfinity/ic/tree/80d2c37e0be4244e1090388ea2039138dc49c881/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 80d2c37e0be4244e1090388ea2039138dc49c881

# 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.


### Upgrade Arguments Verification

[`didc`][latest-didc] is required.

[latest-didc]: https://github.com/dfinity/candid/releases/latest

```
didc encode '()' | xxd -r -p | sha256sum

```

This should match the `arg_hash` field of this proposal.
