CHANGELOG

v6.4.0

January 7, 2025

API BREAKING

  • Enable existing (standalone) chains to use the existing client (and connection) to the provider chain when becoming a consumer chain. This feature introduces the following API-breaking changes. (#2400)

    • Add connection_id and preCCV to ConsumerGenesisState, the consumer genesis state created by the provider chain. If the connection_id is not empty, preCCV is set to true and both provider.client_state and provider.consensus_state are set to nil (as the consumer doesn't need to create a new provider client). As a result, for older versions of consumers, the connection_id in ConsumerInitializationParameters must be empty and the resulting ConsumerGenesisState needs to be adapted, i.e., both connection_id and preCCV need to be removed.

BUG FIXES

  • Bump cosmossdk.io/math to v1.4.0 (#2408)
  • [x/consumer] Updated genesis transform CLI to transform consumer-genesis content exported by v6.2 providers for consumer chains at version v5. Removed transformation for older consumer versions. (#2373)
  • [x/provider] Fixed pagination bug in query for listing the consumer chains. (#2398)
  • [x/provider] Fixed pagination in the list consumer chains query. (#2377)

DEPENDENCIES

FEATURES

  • Enable existing (standalone) chains to use the existing client (and connection) to the provider chain when becoming a consumer chain. This feature introduces the following changes. (#2400)

    • Add connection_id to ConsumerInitializationParameters, the ID of the connection end on the provider chain on top of which the CCV channel will be established. Consumer chain owners can set connection_id to a valid ID in order to reuse the underlying clients.
    • Add connection_id to the consumer genesis state, the ID of the connection end on the consumer chain on top of which the CCV channel will be established. If connection_id is a valid ID, then the consumer chain will use the underlying client as the provider client and it will initiate the channel handshake.

  • [x/consumer] Remove VSCMaturedPackets. Consumer-side changes for ADR 018. (#2372)

  • [x/provider] Add query for consumer genesis time, which corresponds to creation time of consumer clients. (#2366)

  • [x/provider] Allow consumer chains to specify a list of priority validators that are included in the validator set before other validators are considered (#2101)

  • [x/provider] Allow the chain id of a consumer chain to be updated before the chain launches. (#2378)

  • [x/provider] Enable the customization of the slashing and jailing conditions for infractions committed by validators on consumer chains (as per ADR 020). Every consumer chain can decide the punishment for every type of infraction. (#2403)

  • [x/provider] Prevent Opt-In chains from launching, unless at least one active validator has opted-in to them. (#2101)

IMPROVEMENTS

  • [x/democracy/governance] Removal of consumer governance whitelisting functionality (#2381)

STATE BREAKING

  • Allow the chain id of a consumer chain to be updated before the chain launches. (#2378)
  • Bump cosmos-sdk to v0.50.11 (#2458)
  • Enable existing (standalone) chains to use the existing client (and connection) to the provider chain when becoming a consumer chain. (#2400)
  • [x/consumer] Remove VSCMaturedPackets. Consumer-side changes for ADR 018. (#2372)
  • [x/democracy/governance] Removal of consumer governance whitelisting functionality (#2381)
  • [x/provider] Allow consumer chains to specify a list of priority validators that are included in the validator set before other validators are considered (#2101)
  • [x/provider] Enable the customization of the slashing and jailing conditions for infractions committed by validators on consumer chains (as per ADR 020). Every consumer chain can decide the punishment for every type of infraction. (#2403)
