 ### Client Breaking Changes
 
 * [\#8363](https://github.com/cosmos/cosmos-sdk/pull/8363) Addresses no longer have a fixed 20-byte length. From the SDK modules' point of view, any 1-255 bytes-long byte array is a valid address.
-* [\#8346](https://github.com/cosmos/cosmos-sdk/pull/8346) All CLI `tx` commands generate ServiceMsgs by default. Graceful Amino support has been added to ServiceMsgs to support signing legacy Msgs.
 * (crypto/ed25519) [\#8690] Adopt zip1215 ed2559 verification rules.
 * [\#8849](https://github.com/cosmos/cosmos-sdk/pull/8849) Upgrade module no longer supports time based upgrades.
 * [\#8880](https://github.com/cosmos/cosmos-sdk/pull/8880) The CLI `simd migrate v0.40 ...` command has been renamed to `simd migrate v0.42`.
