Ethics: Level 1 vs Level 2?

I noticed that readings 5-10 are new to Level 2 of the CFA, but is there a difference in the Ethics sections (Reading 1 & 2) from Level 1 to Level 2? The Ethics section from these readings seem to be identical to Level 1. Any thoughts?

Dont have the books in front of me but I remember Ethics at L2 introduced: Soft Dollar Standards, Old/New Prudent Investor Rule, and the Research Objectivity Standards. From what I remember on the exam (wrote L2 this past June), the material tested seemed similiar if not identical to the ethics stuff on L1. And I dont remember GIPS being mentioned in the L2 books either.
