 ### Fee Checks in  `DeliverTx`
 Implementing fee checks within the `DeliverTx` function introduces a few requirements:
-- **Deterministic Minimum Fee Requirement**: For the `DeliverTx` process, it is essential to have a deterministic minimum fee requirement. In `CheckTx`, fee is checked by the `CombinedFeeRequirement(globalFees, localFees)`, which considers both `minimum-gas-prices` from `config/app.toml` and `MinimumGasPricesParam` from the globalfee Params (For more details, see [globalfee.md](/modules/globalfee.md)). `CombinedFeeRequirement` contains non-deterministic part: `minimum-gas-prices` from `app.toml`. Therefore, `CombinedFeeRequirement` cannot be used in `DeliverTx`. In `DeliverTx`, only `MinimumGasPricesParam` in globalfee Params is used for fee verification. The code implementation is shown below.

+# Important changes
+
+This version enables relayer incentivization for newly created IBC channels, adds ICA controller functionality and imposes limits on the amount of outgoing ATOM IBC transfers.
+
+With the upgrade of the ICS provider module, the amount of relayer traffic gets significantly reduced due to the introduction of epochs. With epochs, the ICS protocol aggregates validator set updates and sends them every 600 blocks (1 packet/hour) instead of every block. This feature is intended to reduce relayer costs and encourage relayer participation.

 ## What is a delegator?
 
-People that cannot or do not want to operate [validator nodes](/validators/overview.mdx) can still participate in the staking process as delegators. Indeed, validators are not chosen based on their self-delegated stake but based on their total stake, which is the sum of their self-delegated stake and of the stake that is delegated to them. This is an important property, as it makes delegators a safeguard against validators that exhibit bad behavior. If a validator misbehaves, their delegators will move their Atoms away from them, thereby reducing their stake. Eventually, if a validator's stake falls under the top 180 addresses with highest stake, they will exit the validator set.

Eventually, if a validator's stake falls under the top 180 addresses with highest stake, they will exit the validator set.
 
 **Delegators share the revenue of their validators, but they also share the risks.** In terms of revenue, validators and delegators differ in that validators can apply a commission on the revenue that goes to their delegator before it is distributed. This commission is known to delegators beforehand and can only change according to predefined constraints (see [section](#choosing-a-validator) below). In terms of risk, delegators' Atoms can be slashed if their validator misbehaves. For more, see [Risks](#risks) section.

-- `x/auth`: Accounts and signatures.
-- `x/bank`: Token transfers.
-- `x/staking`: Staking logic.
-- `x/mint`: Inflation logic.
-- `x/distribution`: Fee distribution logic.
-- `x/slashing`: Slashing logic.
-- `x/gov`: Governance logic.
-- `ibc-go/modules`: Inter-blockchain communication. Hosted in the `cosmos/ibc-go` repository.

-About the Cosmos Hub: The Cosmos Hub is the first Hub to be launched in the Cosmos Network. The role of a Hub is to facilitate transfers between blockchains. If a blockchain connects to a Hub via IBC, it automatically gains access to all the other blockchains that are connected to it. The Cosmos Hub is a public Proof-of-Stake chain. Its staking token is called the Atom.
