v10.1.1

ibc-go v10.1.1 Release Notes

Notable changes introduced in ibc-go v10.1.1 are highlighted below, view the full changelog for more details.

New Features

The iteration of the protocol, IBC v2 is added alongside the existing IBC protocol:

The new protocol removes channel and connection handshakes, minimising the application interface, reducing complexity and making it easier to use IBC in new domains: connectivity with Ethereum is now possible.
This blog provides an overview of the new protocol, a more technical overview is found in the IBC v2 specification.
Token transfer, and the callbacks middleware is supported with IBC v2.
Existing IBC channels will remain functional, there is no migration to the v2 protocol in this release.

New versioning scheme for modules

Previously, modules in ibc-go have been versioned and branched separately. Starting with the v10 line, modules/light-clients/08-wasmwill follow and release together with ibc-go. The first stable release of 08-wasm will be 08-wasm/v10.0.0. The callbacks module has been included in ibc-go's own module, and is therefore not a separate module anymore.

You can find releases and notes for 08-wasm seperately.

Removal to ease maintenance and reduce attack surface

Removal of the capabilities module
Removal of the fee middleware module
Removal of channel upgradability

Other noteworthy changes

Since the early work started on v10, some important changes also include:

Redaction of ibc-go v9, so that we could also remove ICS20v2 (ics20-2)
Cleanup of API surface, bringing back multiple functions as deprecated to reduce upgrade burden from v8

v8.7.0

53eaba1

v8.7.0

This release contains a fix for ISA-2025-001.

This version addresses a security vulnerability in IBC-go's deserialisation of acknowledgements and we strongly encourage everyone in the affected versions to update their chain immediately. This patch is not state-breaking, so chains can upgrade in a rolling manner. This does not have to be a co-ordinated upgrade. However, validators should upgrade as soon as possible when the release is made available. If the vulnerability is exploited before 2/3 is patched, the chain will halt.

Full Changelog: v8.6.1...v8.7.0

To learn more about ibc-go versioning, please read our RELEASES.md.

IMPORTANT: Please read the migration guides for any versions of ibc-go that you might be going through when upgrading to this version. For example: if you upgrade from the IBC module contained in the Cosmos SDK 0.42.0 to SDK v0.50.9 and ibc-go v8.5.1, please follow:
