At the very least, there is a change to the casefolding algorithm. 
Cherokee was classified as unicameral but is now considered bicameral 
(two cases, like English). Unusually, case-folding Cherokee maps to 
uppercase rather than lowercase.

The full set of changes is listed here:

http://unicode.org/versions/Unicode8.0.0/

Apart from the addition of 7716 characters and changes to 
str.casefold(), I don't think any of the changes will make a big 
difference to Python's implementation. But it would be good to support 
Unicode 8 (to the degree that Python actually does support Unicode, 
rather than just that character set part of it).

Which one are you referring to, Indic_Matra_Category renamed to 
Indic_Positional_Category?
