However, we added some more assembly-level attributes which can be used to tell the difference between versions. They are AssemblyInformationVersionAttribute and AssemblyFileVersionAttribute. Note that they are not present on the 1.0 assemblies.

What about sys.version? Surely this doesn't have to depend on the
assembly version, in which case it could return values as suggested
earlier in the thread...
