TOPIC: Process Groups -> Focus Areas = Just a Rename?

Deep in the weeds on the PMI update webinars. They've renamed Process Groups to 'Focus Areas' (Initiate, Plan, Execute, etc.). But when I look at the outline, it seems... similar?

Is this a substantive change in how they test this, or just a terminology update to align with the 'Principles'? Are the new 'case study' questions going to be tied to these Focus Areas? I need to know if my detailed process flowcharts are obsolete or just need a new header. Help me overthink this!
