# Canonical Chain Upgrades

## Verify release versions

### Releases on Github

If you would like to verify `injectived` or `peggo` version numbers via Docker,
follow the instructions in the [`verify-injective-release`](https://github.com/injective-dev/snippets-inj/tree/main/verify-injective-release) code snippet.

This is useful if you are on an operating system other than Linux,
and would like to independently verify the binaries in each release.

For example, for `v1.16.1`, it should produce the following output:

```text theme={null}
injectived version
Version v1.16.1 (8be67e82d)
Compiled at 20250802-1910 using Go go1.23.9 (amd64)
peggo version
Version v1.16.1 (8be67e82d)
Compiled at 20250802-1913 using Go go1.23.9 (amd64)
```

### Releases on Docker

These are more straightforward, as each binary needs a single command.

For `injectived`, use the following command:

```shell theme={null}
docker run -it --rm injectivelabs/injective-core:v1.16.1 injectived version
```

This should produce output similar to:

```text theme={null}
Version v1.16.1 (8be67e8)
Compiled at 20250802-1909 using Go go1.23.9 (arm64)
```

For `peggo`, use the following command:

```shell theme={null}
docker run -it --rm injectivelabs/injective-core:v1.16.1 peggo version
```

This should produce output similar to:

```text theme={null}
Version v1.16.1 (8be67e8)
Compiled at 20250802-1911 using Go go1.23.9 (arm64)
```

Note that you should replace `v1.16.1` in the commands above
with your intended Injective release version number.

### Checking for matches

Note that the output from the above commmands contain
the following in addition to the version numbers (e.g. `v1.16.1`):

* The binary release hashes (e.g. `8be67e82d`)
* The compiled time stamp (e.g. `20250802-1910`)
* The compiler (e.g. `Go go1.23.9 (amd64)`)

You can verify that these **match** the values stated in the [Injective chain releases](https://github.com/InjectiveLabs/injective-chain-releases/releases) page on Github.

## Deprecated flags

<Warning>
  **Deprecated `statsd` flags (v1.19.0+)**

  The following `injectived start` flags are no longer supported as of v1.19.0 and must be removed from your start command or systemd unit file before upgrading:

  `statsdAgent`, `statsdEnabled`, `statsd-prefix`, `statsd-address`, `statsd-stuck-func`, `statsd-tracing-enabled`, `statsd-profiling-enabled`, `trace-recorder-threshold`

  If any of these flags are present, `injectived` will fail to start after the upgrade. An external validator on testnet encountered this issue informally — remove these flags **before** running `injectived start` on the new version.
</Warning>
