# Upgrade frontend NNS Dapp canister to commit `26ff9fac5f8aedd17f0ec73feb0219a772f2de3a`
Wasm sha256 hash: `ff4496d5433f35273e9c9c5a9263353886c0905baa1297512f13647d6b907480` (`https://github.com/dfinity/nns-dapp/actions/runs/29029621670`)

## Change Log

### Fixed

- Terminate the per-canister cycles Web Workers when leaving the canisters
  page, fixing a memory leak that could crash the tab ("Aw, Snap!") after
  repeatedly navigating in and out of the canisters list with a large fleet.

## Wasm Verification

To build the wasm module yourself and verify its hash, run the following commands from the root of the [nns-dapp repo](https://github.com/dfinity/nns-dapp):

```
git fetch  # to ensure you have the latest changes.
git checkout "26ff9fac5f8aedd17f0ec73feb0219a772f2de3a"
git merge-base --is-ancestor HEAD origin/main && echo "OK" || echo "Commit is not on main branch!"
./scripts/docker-build
sha256sum nns-dapp.wasm.gz
```

You may also want to verify the canister arguments.  In the proposal they are
binary, which is not very readable. Docker provides both binary and text formats
and you can verify that the text format corresponds to the binary `arg_hash`
field in the proposal.

```
cat nns-dapp-arg-mainnet.did
didc encode "$(cat nns-dapp-arg-mainnet.did)" | xxd -r -p | sha256sum
```
