# Upgrade the Governance Canister to Commit 2d4bcba

__Proposer__: jason.zhu at dfinity.org

__Source code__: [2d4bcba47ea10520ff21ce54a8acb9cdb0629317][new-commit]

[new-commit]: https://github.com/dfinity/ic/tree/2d4bcba47ea10520ff21ce54a8acb9cdb0629317


## Features & Fixes

###  Added

####  List Neurons API Change: Query by Subaccount

The `list_neurons` API now supports querying by neuron subaccount.  This is useful for neuron holders who
have many neurons and want to list only the neurons associated with a particular subaccount.

A new field `neuron_subaccounts` is added to the request, which is a list of subaccounts to query
for.  If this field is present, any neurons found will be added to the response.  If duplicate
neurons are found between this field and others, they will be deduplicated before returning the value.

This new field works in the same way that the existing `neuron_ids` field works.

####  Migrating Active Neurons to Stable Memory

In this release, we turn on the feature to migrate active neurons to stable memory:
`migrate_active_neurons_to_stable_memory`. After the feature is turned on, a timer task will
gradually move active neurons from the heap to stable memory. Clients should not expect any
functional behavior changes, since no APIs rely on where the neurons are stored.

###  Changed

* The limit of the number of neurons is increased from 380K to 400K.

## Verification

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

### WASM Verification

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

[prereqs]: https://github.com/dfinity/ic/tree/2d4bcba47ea10520ff21ce54a8acb9cdb0629317/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 2d4bcba47ea10520ff21ce54a8acb9cdb0629317

# 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.
