@Farhad-Shabani Thank you for sharing the issue. I'll try to fix it in this PR because I want to try the fixes with Namada.

Awesome. Thank you, @yito88.
You can update your branch by merging the main, so that won't be getting the test-msrv job failure.

[Farhad-Shabani]

Just noticed the changelog missed. Do you mind @yito88 add the following. I don't have the permission.

- [ibc-client-tendermint] Fix client verification panic on upgrades when the
  `upgrade_path` size is 1.
  ([\#1297](https://github.com/cosmos/ibc-rs/issues/1297))

- [ibc-client-tendermint] Use the user-defined upgrade path for client upgrades,
instead of defaulting to `UPGRADED_IBC_STATE`.
([\#1303](https://github.com/cosmos/ibc-rs/issues/1303))

[yito88]

Thank you for reviewing! I've added change logs.

FYI: I've confirmed that an IBC client on Namada can be upgraded.
