v0.51.0

Overview

This release introduces a few changes for better customizability. The main one is modularizing ICS-24, ICS-02, and ICS-07 trait implementations. This change empowers developers to write Rust light clients succinctly in a smart-contract context like CosmWasm. Also, the default Tendermint client state verifier is now detached to support custom verifiers, if required.

In addition, this version fixes a bug where the consensus state is incorrectly stored when a header with an older height is submitted.

Furthermore, a set of new host keys is added. This makes ibc-rs more consistent with the storage access of ibc-go. Also, access to client update information is merged into a single method; instead of individual details.

This release updates the ibc-proto-rs dependency to v0.42.2. This takes account of the updated MsgUpdateClient and deprecates MsgSubmitMisbehaviour. Also, ibc-derive dependency is updated to v0.6.1.

Finally, the minimum supported Rust version is corrected and updated to 1.71.1.

There are no consensus-breaking changes.
