AppDaemon apps not working 3.0.0b3

My apps were working fine till I updated my docker image, now I get these errors

It seems something to do with this

File “/usr/local/lib/python3.6/site-packages/appdaemon/appdaemon.py”, line 1798, in check_app_updates
self.init_object(app)
File “/usr/local/lib/python3.6/site-packages/appdaemon/appdaemon.py”, line 1438, in init_object
self.objects[name][“object”].initialize()
File “/conf/apps/button_lights.py”, line 19, in initialize
for button in self.split_device_list(self.buttons):
AttributeError: ‘ButtonLights’ object has no attribute ‘split_device_list’

There were a number of breaking changes in the 3,0 beta - in particular you need to change the import statement at the top of your apps.

Thanks for the help its all working fine now, I was trying to look through the old posts to check for breaking changes I must have missed that post.
