 * (types/coin) [#14739](https://github.com/cosmos/cosmos-sdk/pull/14739) Deprecate the method `Coin.IsEqual` in favour of  `Coin.Equal`. The difference between the two methods is that the first one results in a panic when denoms are not equal. This panic lead to unexpected behavior
 * (x/crypto) [#15258](https://github.com/cosmos/cosmos-sdk/pull/15258) Write keyhash file with permissions 0600 instead of 0555.
 * (cli) [#16138](https://github.com/cosmos/cosmos-sdk/pull/16138) Fix snapshot commands panic if snapshot don't exists.
+* (types) [#16145](https://github.com/cosmos/cosmos-sdk/pull/16145) Rename interface `ExtensionOptionI` back to `TxExtensionOptionI` to avoid breaking change.
 
 ### Deprecated
