#   and add the hash to cversions.txt
# The hash values are used to remind developers when the C API number was not
# updated - generates a MismatchCAPIWarning warning which is turned into an
# exception for released version.

# C-API is changed such that binary compatibility is broken, i.e. whenever a
# recompile of extension modules is needed.

# as adding a function pointer to the end of the function table, can be made
# without breaking binary compatibility.  In this case, only the C_API_VERSION
# (*not* C_ABI_VERSION) would be increased.  Whenever binary compatibility is
# broken, both C_API_VERSION and C_ABI_VERSION should be increased.
