 ### Added
 * Added support for free-threaded (GIL-disabled) CPython builds: the Cython extension is compiled with `freethreading_compatible=True` [gh-357](https://github.com/IntelPython/mkl_fft/pull/357)
+* Enabled support of Python 3.15 [gh-378](https://github.com/IntelPython/mkl_fft/pull/378)
 
 ### Changed
 * Raised the minimum build-time `Cython` requirement to `3.1.0`, the first release providing the `freethreading_compatible` directive [gh-357](https://github.com/IntelPython/mkl_fft/pull/357)
