We present here a summary of the most relevant changes, please see the v7.3.2 changelog for the full set of changes included in this release.

dependencies

• Cosmos SDK has been bumped to v0.47.8.
• CometBFT has been bumped to v0.37.4.

core

• The emission of events on erroneous IBC application callbacks was removed due to the huckleberry security advisory. Since then, many users have been unable to debug their IBC applications effectively causing a considerable uptick in support requests across many chains. In this release we are introducing re-enabling emission of events on erroneous IBC application callbacks by appending the prefix ibccallbackerror- to all event type and attribute keys.
