v5.0.0

IRISHub v5.0.0

State-breaking, in-place upgrade from v4.1.0 (irishub-2).
Upgrade plan name: v5.0.0. The upgrade handler must run;
a bare binary swap is not sufficient.

State Machine Breaking

• Cosmos-SDK v0.50.11-lsm -> v0.53.8, IBC-Go v8 -> v10.7.0,
  CometBFT v0.38.21 -> v0.38.23, module github.com/irisnet/irishub/v4
  -> v5, Go 1.23.8. app/upgrades/v500/upgrades.go:17
• Delete store capability and its version-map entry,
  then m.RunMigrations. IBC v10 no longer uses it.
• LSM retirement app/upgrades/v500/lsm.go:
  • Delete legacy staking prefixes 0x81-0x87 (records/indexes);
  • Rewrite staking params/validators/delegations/historical-info
    to strip old fork fields;
  • Reset validator.MinSelfDelegation to 0 to preserve old LSM behavior;
  • Validate tokenize-share record.id/owner/module/validator,
    migrate reward-owner link via distr.SetDelegatorWithdrawAddr(source->owner),
    keep backing delegations and bank balances/supplies untouched.
• irismod / tibc / nft-transfer synced to SDK-0.53 branches
  (20260928 pseudo-versions); IBC transfer denoms migrated
  to the new format with denominations preserved.

Behavior Change

• Legacy LSM txs/queries are gone. Existing tokenize-share assets stay
  backed but cannot be redeemed in this release; redemption needs
  a separately agreed follow-up.
• IBC integrations must use IBC-Go v10.7.0 interfaces, incl.
  client recovery and parameter-update gov messages.

Known Issues

• LSM derivative redemption is unsupported; balances/supplies,
  delegations, and reward-owner mappings are preserved for later handling.
