Fabozzi - Bond Markets, Analysis, and Strategies

Does anyone happen to know the differences between this books 5th edition and 7th edition? I have the 5th edition, but the syllabus for class recommends the 7th edition. I’m assuming not much has changed in it and even if it has with the 5th edition + CFAI level 1 and level 2 books I think I’ll be fine. Or do you guys just think I should buy the 7th edition. Thanks

I was in a similar situation before. I had the 5th edition, but the syllabus recommended 6th edition. The 6th edition had two or three more chapters so I just borrowed the book from the library for those chapters. Otherwise they were identical as far as I can tell.
