they've got rid of loads of courses for my 4th year that were previously available, but i don't think it's to do with the university changes.
Having resit 3rd year just there, I can say it was completely different from my first 3rd year, and apparently everyone else in my class's 1st and 2nd year were completely different from mine too, so i think this is just a planned restructure that's been going on for 4 years.
That said, I'm still not happy, some of the courses that were available to 4th years this year were courses that I had available to me last year like Probability (actually that's the only one that they've gotten rid of that I really wanted to do) are gone. Shame because I passed that exam first time around in 3rd year (only just though) despite attending zero lectures and having another exam on the same day, so only actually studying for it for about 4 hours beforehand.
Imagine how easy it would have been this year putting in effort
