 ## 0.7.0 (UNRELEASED)
+### Added
+- `CTurboShake128` and `CTurboShake256` type aliases generic over domain separator ([#866])
+
 ### Changed
 - Internal implementation by removing unnecessary buffering ([#849])
 - `Rate: BlockSizes` generic parameter to `const RATE: usize` ([#849])
+- `TurboShake128` and `TurboShake256` type aliases are no longer generic over the domain separator
+  and use the default value instead ([#866])
 
 ### Removed
 - Implementations of `BlockSizeUser` ([#856])
