* The :c:member:`PyConfig.module_search_paths_set` field must now be set to 1 for
initialization to use :c:member:`PyConfig.module_search_paths` to initialize
:data:`sys.path`. Otherwise, initialization will recalculate the path and replace
any values added to ``module_search_paths``.

* Distributors are encouraged to build Python with the optimized Blake2

:data:`sys.path`. Otherwise, initialization will recalculate the path and replace

* :c:func:`PyConfig_Read` no longer calculates the initial search path, and will not
fill any values into :c:member:`PyConfig.module_search_paths`. To calculate default
paths and then modify them, finish initialization and use :c:func:`PySys_GetObject`
to retrieve :data:`sys.path` as a Python list object and modify it directly.
