 ## [dev] (MM/DD/YY)
+This release updates `mkl_umath` to be aligned with both numpy-1.26.x and numpy-2.x.x.
 
 ### Added
-* `mkl_umath` is now aligned with both numpy-1.26,x and numpy-2.x.x [gh-65](https://github.com/IntelPython/mkl_umath/pull/65)
+* The definition of `sign` function for complex floating point data types is updated to match numpy-2.x.x [gh-65](https://github.com/IntelPython/mkl_umath/pull/65)
+* `ldexp` function is updated to allow `int64` explicitly similar to numpy-2.x.x behavior [gh-73](https://github.com/IntelPython/mkl_umath/pull/73)
 
 ### Changed 
 * Migrated from `setup.py` to `pyproject toml` [gh-63](https://github.com/IntelPython/mkl_umath/pull/63)
+* Changed to dynamic linking and added interface and threading layers [gh-72](https://github.com/IntelPython/mkl_umath/pull/72)
 
 ### Fixed
 * Fixed a bug for `mkl_umath.is_patched` function [gh-66](https://github.com/IntelPython/mkl_umath/pull/66)
