 * Optimize ``bytes.replace(b'', b'.')`` and ``bytearray.replace(b'', b'.')``:
 up to 80% faster. (Contributed by Josh Snider in :issue:`26574`).
 
+* Allocator functions of the :c:func:`PyMem_Malloc` domain
+ (:c:data:`PYMEM_DOMAIN_MEM`) now use the :ref:`pymalloc memory allocator
+ <pymalloc>` instead of :c:func:`malloc` function of the C library. The
+ pymalloc allocator is optimized for objects smaller or equal to 512 bytes
+ with a short lifetime, and use :c:func:`malloc` for larger memory blocks.
