-## Regen Ledger v2.0.0
+## Regen Ledger v2.1.0
 
-Regen Ledger v2.0.0 includes an upgrade to Cosmos SDK v0.44 and the addition of three new modules: the authz module, the feegrant module, and the ecocredit module.
+### IBC Patch Upgrade
 
-### Cosmos SDK
+Regen Ledger `v2.1.0` includes an important fix for Regen Mainnet which recently upgraded to Regen Ledger `v2.0.0`.  In the `v2.0.0` upgrade, a bug was introduced that made all new IBC transactions fail to be processed.
 
-For more information about Cosmos SDK v0.43 and Cosmos SDK v0.44, see the release notes:

-- [Cosmos SDK v0.43.0 Release Notes](https://github.com/cosmos/cosmos-sdk/blob/release/v0.43.x/RELEASE_NOTES.md)
-- [Cosmos SDK v0.44.0 Release Notes](https://github.com/cosmos/cosmos-sdk/blob/release/v0.44.x/RELEASE_NOTES.md)
-
-### Authz Module
-
-The authz module enables a granter to grant an authorization to a grantee that allows the grantee to execute a message on behalf of the granter. For more information about the authz module, see the [Authz Module Specification](https://docs.cosmos.network/master/modules/authz/).
-
-### Feegrant Module
-
-The feegrant module enables the ability for a granter to grant an allowance to a grantee where the allowance is used to cover fees for sending transactions. For more information about the feegrant module, see the [Feegrant Module Specification](https://docs.cosmos.network/master/modules/feegrant/).
-
-### Permanent Locked Accounts
-
-Regen Ledger v2.0 supports the on-chain creation of permanent locked accounts through the `MsgCreatePermanetLockedAccount` message. These special types of accounts are intended to be used by Regen Foundation for seeding Community Staking DAOs, wherein the initial REGEN funds distributed to these accounts must be permanently locked and only usable for governance and staking. For more information see [regen-ledger#188](https://github.com/regen-network/regen-ledger/issues/188)
-
-### Ecocredit Module
-
-The ecocredit module enables the ability to manage classes of ecosystem service credits and to mint credits through a batch issuance process. For more information about the ecocredit module, see the [Ecocredit Module Specification](https://docs.regen.network/modules/ecocredit/).
+This release (`v2.1.0`) hard codes an emergency height-based upgrade which introduces a consensus-breaking change at height `3126912` that resolves the issue. All production validators and full-nodes must update to `v2.1.0` prior to the upgrade height (estimated for Friday Nov 26, 17:00 UTC).
