@@ -14,13 +14,17 @@ and this project adheres to
   of CosmWasm earlier than 1.2.0 ([#1481]).
 - cosmwasm-std: Add `instantiate2_address` which allows calculating the
   predictable addresses for `MsgInstantiateContract2` ([#1437]).
+- cosmwasm-std: Add `WasmMsg::Instantiate2` (requires `cosmwasm_1_2`, see
+  `GovMsg::VoteWeighted` above) to instantiate contracts at a predictable
+  address ([#1436]).
 - cosmwasm-schema: In contracts, `cosmwasm schema` will now output a separate
   JSON Schema file for each entrypoint in the `raw` subdirectory ([#1478],
   [#1533]).
 - cosmwasm-std: Upgrade `serde-json-wasm` dependency to 0.5.0 which adds map
   support to `to_vec`/`to_binary` and friends.
 - cosmwasm-std: Implement `AsRef<[u8]>` for `Binary` and `HexBinary` ([#1550]).
