In her interview with the Mad Fientist, Vicki Robin talks about the changes to the new edition. Essentially just updating it for the modern world: budgeting apps, DIY investing platforms, etc. When they first wrote it Treasury bonds were returning something ridiculous like 15%, so obviously those forecasts and recommendations had to be updated. Overall it is a very interesting interview so I highly recommend listening to that episode!https://www.madfientist.com/vicki-robin-interview/
