 * [\#5785](https://github.com/cosmos/cosmos-sdk/issues/5785) JSON strings coerced to valid UTF-8 bytes at JSON marshalling time
 are now replaced by human-readable expressions. This change can potentially break compatibility with all those client side tools
 that parse log messages.
+* (client) [\#5799](https://github.com/cosmos/cosmos-sdk/pull/5799) The `tx encode/decode` commands, due to change on encoding break compatibility with

   * The module now accepts a `Codec` interface which extends the `codec.Marshaler` interface by
   requiring a concrete codec to know how to serialize `Proposal` types.
-* (codec) [\#5799](https://github.com/cosmos/cosmos-sdk/pull/5799) Now we favor the use of MarshalBinaryBare instead of LengthPrefixed in all cases that is not needed.
