+## [1.2.7] - 2023-06-19
+
+### Added
+
+- cosmwasm-std: Add `<<` and `<<=` implementation for `Uint{64,128,256,512}`
+  types. ([#1723])
+- cosmwasm-std: Add `Timestamp::{plus,minus}_{minutes, hours, days}`. ([#1729])
+- cosmwasm-std: Add `Decimal::bps` and `Decimal256::bps` to create a decimal
+  from a basis point value ([#1715]).
+
+[#1723]: https://github.com/CosmWasm/cosmwasm/pull/1723
+[#1729]: https://github.com/CosmWasm/cosmwasm/pull/1729
+[#1715]: https://github.com/CosmWasm/cosmwasm/pull/1715
+
+### Changed
+
+- cosmwasm-std: Coin uses shorter `Coin { 123 "ucosm" }` format for Debug
+  ([#1704])
+
+[#1704]: https://github.com/CosmWasm/cosmwasm/pull/1704
