Examples of a large-scale physics syllabus review
You might want to take a look at Germany (and possibly other countries an Europe). Due to the Bologna reform, physics departments (and many other ones) were forced to switch their curriculum from the old diploma system to a bachelor–master system somewhere around 2005 (the exact year depends on the university).

At least my university used this for some restructuring of the contents and, e.g., did the following (just to give you an idea):


Introduced separate math courses for physicists (before, students of physics and mathematics attended the same courses).
Introduced special courses each for IT, presentations and numerics (before, students were supposed to learn this by themselves on the way or when they actually needed it)
Moved theoretical mechanics and electrodynamics one semester earlier.
Merged the courses on atomic physics and condensed-matter physics as well as the courses on nuclear and particle physics.


Other universities might have undergone even more radical changes.
