+API Changes for 3.9.2
+=====================
+
+Development
+-----------
+
+Windows wheel runtime bundling made static
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+In 3.7.0, the MSVC runtime DLL was bundled in wheels to enable importing Matplotlib on
+systems that do not have it installed. However, this could cause inconsistencies with
+other wheels that did the same, and trigger random crashes depending on import order. See
+`this issue <https://github.com/matplotlib/matplotlib/issues/28551>`_ for further
+details.
+
+Since 3.9.2, wheels now bundle the MSVC runtime DLL statically to avoid such issues.
