Yes, bitbake understands versions. And by default it will chose the 
'latest'/'highest':

E.g.:
XYZ_1.0.bb
XYZ_2.0.bb 
--> bitbake will build  XYZ_2.0

But:
XYZ_1.0.bb
XYZ_2.0.bb
XYZ_git.bb
--> bitbake will build  XYZ_git as it is considered the 'latest'.

We can tweak this in the local.conf with
PREFERRED_VERSION_XYZ="2.0"

Yes, you can version your recipes and make API changes visible by changing the 
version number.
