Marcus can comment on his script...

For each release there is a set of compatible images. Also, all of the
development happens on the master branch, so if you update your host
code to the latest master branch, you will often have to update the
images package. The host code will perform a compatibility check and
throw an exception if the compatibility does not match.

Images and release binaries can be found here (including images that
will work with the latest master branch):

These are not APIs, they are executable files; and generally they have
this naming convention.

Most often, they have the name usrp2 in them.
