It should mostly work. I just checked our CHANGES.txt file and haven't seen much incompatibilities introduced between those releases.

But 0.20.3 is pretty old, so only one way to know for sure - compile and run against 1.x.

If you are making that jump, you may as well use the latest releases in 1.x line.

Thanks,
