 ### Improvements
 
+* (events) [#12850](https://github.com/cosmos/cosmos-sdk/pull/12850) Add a new `fee_payer` attribute to the `tx` event that is emitted from the `DeductFeeDecorator` AnteHandler decorator.
 * (ci) [#12854](https://github.com/cosmos/cosmos-sdk/pull/12854) Use ghcr.io to host the proto builder image.  Update proto builder image to go 1.19
 * (x/bank) [#12706](https://github.com/cosmos/cosmos-sdk/pull/12706) Added the `chain-id` flag to the `AddTxFlagsToCmd` API. There is no longer a need to explicitly register this flag on commands whens `AddTxFlagsToCmd` is already called.
 * [#12791](https://github.com/cosmos/cosmos-sdk/pull/12791) Bump the math library used in the sdk and replace old usages of sdk.*
