I thought .show was depreciated in 8.x and removed in 9.x?

#8456

[ladyada]

ooh ok that maybe what im forgetting!

[DJDevon3]

show is still valid in 8.x and will be the last version it is valid.
transitioning to total deprecation of display.show in 9.x in favor of display.root_group
do something like this instead

main_group = displayio.Group
display.root_group = main_group

We just discussed this in our internal meeting. We decided to add a show() function implementation that raises an exception when used to specify how to fix the code.
