NEW LOG ERRORS ON KODI v17.

Dear Kodi.tv,

i recently updated from kodi v16 to kodi v17 and now have issues with over half of my addons. I love your app and have been using it for over 2 years
but guess i shouldnt trust newer versions. I now get the following error when trying to use someof my addons:

T:3876 ERROR Control 50 in window 10001 has been asked to focus but it cant.
->End of Python script error report<-
AttributeError: ‘module’ object has no attribute ‘PLAYER_CORE_AUTO’
xbmc.Player = xbmc.Player(xbmc.PLAYER_CORE_AUTO)

please help me. I was runnung smoothly before downloading kodi v17. ty
