UPDATES

• 25th May 2023: This release is NOT recommended since it includes by mistake a state-machine breaking change. Please use version >= 4.1.3.

This release includes a fix for the huckleberry security advisory. Credits to Felix Wilhelm (@felixwilhelm) of Jump Crypto for the discovery and responsible disclosure via our bug bounty program.

Please see the v4.1.2 changelog for the full set of changes included in this release.

Please note that the v4 release line contains a bug where fee-enabled Interchain Accounts channels cannot be reopened in case of channel closure due to packet timeout. Regular Interchain Accounts channels (i.e. non fee-enabled) can be reopened. In order to be able to reopen fee-enabled Interchain Accounts channels, please upgrade to v5.2.1 or above.
