Here in the Netherlands, we switched to 3 + 2 years of BSc + MSc from a 5 year degree a while back.
The actual program didn't change, just the diplomas you get in the end. Based on this, I'm comfortable saying that an MSc given these days is essentially the old 5 year degree.
I was studying physics in Germany right when the transition from 5-year diploma to 3+2 BSc+MSc happened. While most parts of the curriculum stayed the same, faculty took the opportunity to modernize the curriculum. For example, Computational Physics (an introductory programming course with a focus on numerical calculation methods and how to deal with precision-induced numerical errors) was upgraded from optional to mandatory, given that nearly all physicists have to write some code these days.
Outside the US and countries that ape its university system there are no general education requirements. You study your degree subject and nothing else. The well rounded citizen stuff is presumed covered in secondary school.
The 5-year degrees that existed in most of Europe before bologna were not centered around being a "well-rounded citizen". They were centered around being a "well-rounded" major.
In CS, this means that you were taught courses ranging from basic Electrical Engineering all the way to Artificial Intelligence, including physics, algebra, calculus, signal processing, theory of computation, algorithms, databases, computer architecture, compilers, computer networks, robotics, etc.. That is, you got introductory-level courses on everything that makes "computer-stuff", and then there were a number of optional courses where you specialized.
I really don't think you can cover all that material in 3 years...
That is what I have been told from German friends, hence my assertion.
Looking at the contents of 3 years bachelor + 2 years MS, versus the contents of old Licentiate 5 years duration in Portugal, they are clearly equivalent in content.
Hence why after Bologna many universities basically renamed their Licentiate degree into something called Integrated MS, which means the students get a BS + MS paper at the end of those 5 years.
Also the reason why former Licentiates are allowed to basically acquire their MS title, by paying bureaucratic fees and in some cases presenting some kind of career report as thesis.
The actual program didn't change, just the diplomas you get in the end. Based on this, I'm comfortable saying that an MSc given these days is essentially the old 5 year degree.
