  +Updating ISPC Programs For Changes In ISPC 1.13.0
  +-------------------------------------------------
  +
  +This release contains the following changes that may affect compatibility with
  +older versions:
  +
  +* Representation of ``bool`` type in storage was changed from target-specific to
  + one byte per boolean value. So size of ``varying bool`` is target width (in
  + bytes), and size of ``unform bool`` is one. This definition is compatible
  + with C/C++, hence improves interoperability.
  +
  +* type aliases for unsigned types were added: ``uint8``, ``uint16``, ``uint32``,
  + ``uint64``, and ``uint``. To detect if these types are supported you can
  + check if ISPC_UINT_IS_DEFINED macro is defined, this is handy for writing code
  + which works with older versions of ``ispc``.
  +
  +* ``extract()``/``insert()`` for boolean arguments, and ``abs()`` for all integer and
  + FP types were added to standard library.
