 ### DEPENDENCIES
 
 - Bump [cosmos-sdk](https://github.com/cosmos/cosmos-sdk) to
   [v0.47.10](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.47.10).
   ([\#1663](https://github.com/cosmos/interchain-security/pull/1663))
+- Bump [ibc-go](https://github.com/cosmos/ibc-go) to

+  ([\#1764](https://github.com/cosmos/interchain-security/pull/1764))
 
 ### FEATURES
 
 - [Provider](x/ccv/provider)
   - Introduce epochs (i.e., send a VSCPacket every X blocks instead of in every
     block) so that we reduce the cost of relaying IBC packets needed for ICS.
     ([\#1516](https://github.com/cosmos/interchain-security/pull/1516))
+  - Introduce the gRPC query `/interchain_security/ccv/provider/oldest_unconfirmed_vsc/{chain_id}`
+    and CLI command `interchain-security-pd q provider oldest_unconfirmed_vsc`
+    to retrieve the send timestamp of the oldest unconfirmed VSCPacket by chain id.

 `v3.2.0` bumps IBC to `v7.3`. As a result, `legacy_ibc_testing` is not longer required and was removed, see https://github.com/cosmos/interchain-security/pull/1185. This means that when upgrading to `v3.2.0`, any customized tests relying on `legacy_ibc_testing` need to be updated.
