-* (ante) [#11413](https://github.com/cosmos/cosmos-sdk/pull/11413) Refactor tx middleware to support pluggable feemarket module. The API breakages: a) Removed `MempoolFeeMiddleware` and `TxPriorityMiddleware`, the functionalities are moved into `DeductFeeMiddleware`, b) Added a `FeeMarket` field to `HandlerOptions`, and a `FeeMarket` parameter to `DeductFeeMiddleware`, when set to `StaticFeeMarket{}`, it'll keep the existing behavior, c) Added an `extention_options` field to `AuthInfo` in `Tx`, d) Added a `NewAuthExtensionOptionsMiddleware` middleware to check the `extension_options` field.
+* (ante) [#11413](https://github.com/cosmos/cosmos-sdk/pull/11413) Refactor tx middleware to support pluggable feemarket module. Merged `MempoolFeeMiddleware` and `TxPriorityMiddleware` functionalities into `DeductFeeMiddleware`, so the potential feemarket module can implement these logic in one pass. Added a `FeeMarket` interface to plug-in different feemarket implementation in tx middleware, current fee logic is preserved by the default `ValidatorTxFee` implementation. Added an `extention_options` field to `AuthInfo`, so feemarket module can add extra fields to tx.
