 ### Added
+* Enabled support of Python 3.15 [gh-279](https://github.com/IntelPython/mkl_umath/pull/279)
 * Added support for free-threaded (GIL-disabled) CPython builds: the Cython extension is compiled with `freethreading_compatible=True` and `_ufuncs` declares `Py_MOD_GIL_NOT_USED`, so importing `mkl_umath` no longer re-enables the GIL [gh-255](https://github.com/IntelPython/mkl_umath/pull/255)
