 * [\#10507](https://github.com/cosmos/cosmos-sdk/pull/10507) Add middleware for tx priority.
 * [\#10311](https://github.com/cosmos/cosmos-sdk/pull/10311) Adds cli to use tips transactions. It adds an `--aux` flag to all CLI tx commands to generate the aux signer data (with optional tip), and a new `tx aux-to-fee` subcommand to let the fee payer gather aux signer data and broadcast the tx
 * [\#10430](https://github.com/cosmos/cosmos-sdk/pull/10430) ADR-040: Add store/v2 `MultiStore` implementation
+* [\#10947](https://github.com/cosmos/cosmos-sdk/pull/10947) Add `AllowancesByGranter` query to the feegrant module
