Definitely. The unicode version would have to be frozen with beta 1 if 
not before. (I am quite sure the decimal module also freezes the IEEE 
standard version *it* follows for each Python version.)

In my view, x.y is a version of the Python language while the x.y.z 
CPython releases are progressively better implementations of that one 
language, starting with x.y.0. This is the main reason I suggested that 
the first CPython release for the 3.3 language be called 3.3.0, as it 
now is. In this view, there is no question of an x.y.z+1 release 
changing the definition of the x.y language.
