 ## Delta Upgrade (Completed July 12, 2021)
-
+- Gaia v5.0.x
 - Gravity DEX:
   - A scalable AMM model for token swaps
   - Drives liquidity for tokens on the Cosmos Hub
   - Delivers price consistency and order execution
 
 ## Vega Upgrade (Completed December 14, 2021)

+## v7-Theta Upgrade (expected Q1 2022)
+- Gaia v7.0.x
 - Cosmos SDK v0.45
+  - Minimal update with small fixes
+- IBC 3.0
+  - Interchain Account Module
+    - Allows the creation of accounts on a "Host" blockchain which are controlled by an authentication module on a "Controller" blockchain.
+    - Arbitrary messages are able to be submitted from the "Controller" blockchain to the "Host" blockchain to be executed on behalf of the Interchain Account.
+    - Uses ordered IBC channels, one per account.
+- Interchain Account Message Auhothorization Module
+    - Authentication module that authorizes any Account to create an Interchain Account on any IBC connected "Host" blockchain that has the Interchain Account IBC module.
+    - Accounts can be private key controlled users, and eventually the Gov Module and any Groups Module.

+## v8-Rho Upgrade (expected Q2 2022)
+- Gaia v8.0.x
+- Cosmos SDK v0.46
   - Groups module:
     - Enables higher-level multisig permissioned accounts, e.g., weight-based voting policies

   - Enable simple management of NFT identifiers, their owners, and associated data, such as URIs, content, and provenance
   - An extensible base module for extensions including collectibles, custody, provenance, and marketplaces
 - Tendermint v0.35
-- Interchain accounts
-  - A requirement in order to manage accounts across multiple blockchains
-  - Aims to provide locking/unlocking mechanisms across IBC-enabled blockchains
-  - Would allow custody providers to service any IBC connected blockchain through a common interface on the Hub.
 - Liquid Staking
   - Frees secure and low-risk delegations for use in other parts of the Cosmos ecosystem
   - Features include enabling transfer of rewards and voting rights
-- Items still being discussed:
-  - Governance permissioned CosmWASM instance on the hub
-  - Budget Module
-    - Inflation funding directed to arbitrary module and account addresses
-  - Farming Module
-    - Rewards for locked tokens, especially LP tokens for different trading pair pools

+## v9-Lambda Upgrade (expected Q3 2022)
+- Gaia v9.0.x
 - Interchain Security v1 - Required Participation of Provider Chain Validators
   - The Cosmos solution to shared security that uses IBC Cross Chain Validation (CCV) to relay validator set composition from a Provider Chain (Cosmos Hub) to a Consumer Chain. This validator set is in charge of producing blocks on both networks using separate nodes. Misbehavior on the Consumer Chain results in slashing Provider Chain staking tokens (ATOM).
   - Allows independent modules like Gravity DEX or Bridge to live on separate chains with their own development cycles.

+## Future Considerations
+The Cosmos Hub is a decentralized network with many diverse contributors. As such there is no one authority of what is or can be part of the Cosmos Network. The Cosmos Hub team at Interchain does it's best to maintain the Gaia repository, which is the primary codebase that operates the Cosmos Network. The Interchain Foundation is one of the sources of funding for engineering work that may make its way onto the Cosmos Hub. We do our best to participate in ongoing conversations about the mission, vision and purpose of the Cosmos Hub, so that we can best support work to enabling it via funding, engineering, coordination and communication. Some of the topics which have been discussed by contributors inside and outside of Interchain are listed below, although have not been developed to the point of being included in the roadmap:
+* Privacy
+* Smart Contracts
+* Rollups
 
 The Cosmos Hub Roadmap is maintained by the Interchain Cosmos Hub team as a living document, and is updated in collaboration with key stakeholders from the multi-entity Cosmos community.
