Hi Nanie,
There's lot happened in the SAP world especially look & feel from EHP0 to EHP7,
Even SAP focused more on this aspect.
As you can see the differences, FONTs are much darker,bigger with lighter background helping much easier end user eye experience, lines are much lighter, a much better cool effect as this is part of SAP Corbu/Gold Reflection theming.
So move with new change rather older version.
