 ### State Machine Breaking
 
+* (baseapp, x/auth/posthandler) [#13940](https://github.com/cosmos/cosmos-sdk/pull/13940) Update `PostHandler` to receive the `runTx` success boolean.
 * (x/group) [#13742](https://github.com/cosmos/cosmos-sdk/pull/13742) Migrate group policy account from module accounts to base account.
 * (codec) [#13307](https://github.com/cosmos/cosmos-sdk/pull/13307) Register all modules' `Msg`s with group's ModuleCdc so that Amino sign bytes are correctly generated.
 * (codec) [#13196](https://github.com/cosmos/cosmos-sdk/pull/13196) Register all modules' `Msg`s with gov's ModuleCdc so that Amino sign bytes are correctly generated.

 ### PostHandler
 
-_PostHandler_ are like `AnteHandler` (they share the same signature), but they execute after [`RunMsgs`](#runmsgs).
+`PostHandler` is similar to `AnteHandler`, but it, as the name suggests, executes custom post tx processing logic after [`RunMsgs`](#runmsgs) is called. `PostHandler` receives the `Result` of the the `RunMsgs` in order to enable this customizable behavior.
 
 Like `AnteHandler`s, `PostHandler`s are theoretically optional, one use case for `PostHandler`s is transaction tips (enabled by default in simapp).
 Other use cases like unused gas refund can also be enabled by `PostHandler`s.
