+## [1.3.0] - 2024-08-15
+
+### Added
+- support for Maya 2024
+- support for Python 3.11
+- added source code comments to python wrappers
+
+### Fixed
+- `CalculateMeshLowerLODsCommand` was rewritten to address edge cases discovered with eyelashes and to handle some common cases of invalid UV data. 
+- `RotateCommand` to rotate blend shape target deltas as well.
+- `SetBlendShapeTargetDeltasCommand` to allow setting vertex indices as well.
+- Swig generated classes are now wrapped instead of being monkey-patched to invoke constructors and destructors (which allows building with newer Swig versions - 4.0.x and 4.1.x).
+
+### Changed
+- CMake files to add test cases that execute the example scripts and allow generating bundled archives with CPack. 
+- Binaries for embeddedRL4 plugin to be .so files.
+
+
+## [1.2.0] - 2023-06-30
+
+### Added
+- assets (gui.ma, Ada.dna, additional_assemble_script.py) which support MHC 2.x.x releases (UE 5.2 and 5.3)
+
+
 ## [1.1.0] - 2023-04-20
