No clue when you updated ..

You could try to backport but be warned that the arrow macros have been 
changed because of more possibilities in the open type fonts (so there 
is a relationship with fonts too).

Why don't you use version numbers and store pdf files? After all, it's 
quite normal that educational materials get updated. Also, use 
references to numbers instead of pages.

The recent reimplementation of arrows was stand-alone and the old 
math-arr.mkiv code is still there so you can try to load that file.

I don't know if Mojca still keeps old betas and checks them in in her 
public git repos.
