v2.3.0
UPDATES
- 27th October 2022: This release is NOT recommended since it uses a version of the Cosmos SDK impacted by the dragonberry security advisory. Please use version >= 2.4.2.
Please note that, according to ibc-go's semantic versioning, this release requires a coordinated upgrade because it contains state-machine breaking changes. This release requires also running a migration.
This release bumps the Go version to v1.17 and the Cosmos SDK to v0.45.4 (for more information, see Cosmos SDK v0.45.4 Release Notes), and introduces several improvements and bug fixes. We present here a summary of the most relevant changes, but please see the v2.3.0 changelog for the full set of changes included in this release.

- A gRPC query method and CLI query has been added to retrieve the heights of all consensus states associated with the a given client ID.
core/04-channel

DenomTracegRPC method and CLI query can now take as argument either a trace hash or a full IBC denom prefixed withibc/. - The sender address is now added in the event emitted in the
OnRecvPacketandOnAcknowledgementPacketcallbacks. - A gRPC query method has been added to retrieve the escrow address for a particular channel.
- Support for token transfers of coins whose base denomination contains slashes has been added. For the transfer of coins whose base denomination contains slashes to succeed, both the sending and the receiving chains need to upgrade to add this support. Please follow also the migration guide.
