Passage v4.0.2

Scheduled upgrade following the v4.0.1 emergency fix.

Changes

CometBFT v0.38.12 → v0.38.23

  • Restores working transaction reindexing (passage tendermint reindex-event).
  • Includes all accumulated fixes from the v0.38.x release line.

IAVL v1.2.2 → v1.2.3

  • Fixes a significant performance regression (iavl#1018).
  • getFirstVersion() now correctly caches its result on chains using legacy-format versions (which includes every chain upgraded through v4.0.0).
  • Applied to the vendored iavl-fork on top of the existing empty-store load fix.

x/group

Introduces the new x/group module (new store), enabling:

  • On-chain multisig-style groups.
  • Weighted group members.
  • Decision policies.
  • Proposal execution.

Coordination

This is a consensus-breaking upgrade because it introduces a new store.

The upgrade is activated through a governance software-upgrade proposal:

  • Plan name: v4.0.2
  • Activation: Governance proposal (not a flag-day upgrade)

Validators should either:

  • Stage the new binary for Cosmovisor:
upgrades/v4.0.2/bin/passage
  • Or be prepared to manually swap the binary at the upgrade halt.

Important: The upgrade handler name must be exactly:

v4.0.2

Verification

Validated using real-broadcast fork testing against forked mainnet state.

Verified successfully:

  • Governance software upgrade applied:

    applying upgrade "v4.0.2"

  • Module version map includes:

    group: 2

  • Regression transactions for:

    • bank
    • staking
    • distribution

    all returned:

    code: 0

  • Complete x/group lifecycle tested successfully:

    1. Create group with policy
    2. Fund policy account
    3. Submit group proposal executing a MsgSend
    4. Vote
    5. Execute proposal

All transactions completed with:

code: 0

Balances updated correctly throughout the workflow.
