------------------------------------------
Full list of changes (including the ones that are not relevant to HostOS) can be found on [GitHub](https://github.com/dfinity/dre/blob/2f7a48821b6c09cdf3dff2da8dc88fbf847a4336/hostos-releases/8f1ef8ce78361adbc09aea4c2f0bce701c9ddb4d.md).

# IC-OS Verification

To build and verify the IC-OS HostOS disk image, after installing curl if necessary (`sudo apt install curl`), run:

```
# From https://github.com/dfinity/ic#verifying-releases
curl -fsSL https://raw.githubusercontent.com/dfinity/ic/master/ci/tools/repro-check | python3 - -c 8f1ef8ce78361adbc09aea4c2f0bce701c9ddb4d --hostos
```

The two SHA256 sums printed above from a) the downloaded CDN image and b) the locally built image, must be identical, and must match the SHA256 from the payload of the NNS proposal.

While not required for this NNS proposal, as we are only electing a new HostOS version here, you have the option to verify the build reproducibility of the GuestOS by passing `--guestos` to the script above instead of `--hostos`, or the SetupOS by passing `--setupos`.
