Version 3.0->3.1.1 is only for 7.0.0
Version 3.1.2 is only for 7.0.1+
Version 4.0 is only for 8.0+
IMPORTANT - PowerSchool no longer allows students to edit their own student record. Because of this 1x Class Registration ONLY works when logged in as a Guardian. Students will have full Class Registration ability if 1x is enabled. I am unsure of what version this happened in, just fyi.
This is a new Parent Portal with more options for student screens.
