+* (feat!) Add DistributionTransmissionChannel to ConsumerAdditionProposal [#965](https://github.com/cosmos/interchain-security/pull/965)
 * (feat/fix) limit vsc matured packets handled per endblocker [#1004](https://github.com/cosmos/interchain-security/pull/1004)
 * (fix) cosumer key prefix order to avoid complex migrations [#963](https://github.com/cosmos/interchain-security/pull/963) and [#991](https://github.com/cosmos/interchain-security/pull/991). The latter PR is the proper fix.
 * (feat) v1->v2 migrations to accommodate a bugfix having to do with store keys, introduce new params, and deal with consumer genesis state schema changes [#975](https://github.com/cosmos/interchain-security/pull/975) and [#997](https://github.com/cosmos/interchain-security/pull/997)
