That function was removed. There is a csoundGetVersion().

in line 77-78 of ctcsound.py i see:

APIVERSION = libcsound.csoundGetAPIVersion()
VERSION = libcsound.csoundGetVersion()

is there no difference any more between API version and version, or is 
there another function to return the version?

François will know better but I think you just remove the line for the function that doesn't exist.

so if i get it right, there is no difference any more between csound 
version and api version.

There is no separate API version string anymore.

PS and if someone hits the same issue:
this was not the new version of ctcsound but an older version of 
eduardo's wrapper which is now (much better) called libcsound 
(https://github.com/csound-plugins/libcsound).
françois' new version for the CS7 API ist still called ctcsound and 
works perfectly.
for the difference between both versions françois added a paragraph at 
https://csound.com/csound-python.html.
the source file is 
https://github.com/csound/csound/blob/develop/Python/ctcsound.py
