Notable changes introduced in ibc-go v10.3.0 are highlighted below, view the full changelog for more details.

Prefix-based routing in the IBC v2 router

This release adds the capability for the IBC v2 router to associate port ID prefixes with modules, not only exact port IDs like it was in the case in previous versions.

Parse IBC v2 packet from ABCI events in tests

Parsing IBC packets from ABCI events in tests has been a much-used feature of the ibc-go testing library, and in this release we're adding support for parsing IBC v2 packets as well from the ABCI events in unit and e2e tests.

⚠️ Note: the previous function names for parsing packets from ABCI events have been deprecated and will be removed in a future major release of ibc-go.
