v0.50.0

Overview

This release introduces several noteworthy libraries. A standout addition is the implementation of the ICS-721 NFT transfer application, enabling the transfer of NFT packets across chains that support this capability.

In addition, It incorporates the ICS-08 Wasm light client data structure and types. This empowers light client developers to create CosmWasm contracts for deployment on Cosmos chains compatible with the version of ibc-go supporting ICS-08 Wasm client.

Furthermore, this release addresses the issue with the macro derivation of the ClientState when contexts include generic types, exposes additional convenient types and serializers through ibc-primitives and includes a more flexible constructor for MockContext types within the ibc-testkit crate, allowing to write tests with diverse parameter combinations.

There are no consensus-breaking changes.

Contributors ❤️

Huge shout-out to the Heliax team and a special thanks to @yito88 from their crew for rocking the implementation of ICS-721 and smoothly integrating that into ibc-rs.
