# Upgrade the Governance Canister to Commit 2450f6d

__Proposer__: jason.zhu at dfinity.org

__Source code__: [2450f6dd9beb5e2049a7b201e7b54f28e9d63815][new-commit]

[new-commit]: https://github.com/dfinity/ic/tree/2450f6dd9beb5e2049a7b201e7b54f28e9d63815


## Features & Fixes

###  Added

- Proposal type `DeleteSubnet`, currently limited to CloudEngine subnets.
- Tag neurons that have the maximum dissolve delay of 8 years with their bonus base
  (`eight_year_gang_bonus_base_e8s`), in preparation for the dissolve delay bonus
  grandfathering when the maximum dissolve delay is reduced to 2 years.
- Expose data that will be used to determine the bonus that "8 year gang" neurons
  will receive, starting in the near future. This data consists of the staked amount
  in neurons with 8 year dissolve delay at the beginning of Mission 70. This will be
  used in the near future to determine voting power (and consequently, voting rewards),
  once other aspects of voting power/rewards are in production.

## 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/2450f6dd9beb5e2049a7b201e7b54f28e9d63815/rs/nervous_system/docs/proposal_verification.md


### WASM Verification

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

[prereqs]: https://github.com/dfinity/ic/tree/2450f6dd9beb5e2049a7b201e7b54f28e9d63815/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 2450f6dd9beb5e2049a7b201e7b54f28e9d63815

# 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.
