+## 0.3.30 [2023-10-13]
+
+### Added
+
+- `powerfmt::smart_display::SmartDisplay` has been added for the main types in the library. These
+  implementations ensure that values follow the requested fill, width, and alignment when using
+  `format!` or similar macros. `Display` is implemented in terms of `SmartDisplay`.
+
+### Fixed
+
+- Large values no longer wrap around in release mode when using `NumericalDuration` or
+  `NumericalStdDuration`.
