CHANGELOG.md

@@ -185,6 +185,7 @@ Ref: https://keepachangelog.com/en/1.0.0/
     * The signature of `VerifySignature` has been changed to accept a `x/tx/signing.HandlerMap` and other structs from `x/tx` as arguments.
     * The signature of `NewTxConfigWithTextual` has been deprecated and its signature changed to accept a `SignModeOptions`.
 * (x/genutil) [#15999](https://github.com/cosmos/cosmos-sdk/pull/15999) Genutil now takes the `GenesisTxHanlder` interface instead of deliverTx. The interface is implemented on baseapp
+* (types/math) [#16040](https://github.com/cosmos/cosmos-sdk/pull/16040) Remove unused aliases in math.go
