From time-to-time sabyenc is updated. Which can cause an error such as this one if using a 'master' branch of SABnzbd: "SABYenc disabled: no correct version found! (Found v3.4.0, expecting v3.3.2)"
This means a manual downgrade of the newer sabyenc:
In this case they are really not backwards compatible, since 3.4.0 has extra output variables.
It's already the case for minor versions (3.3.1 -> 3.3.2) that there are no errors, but for bigger changes they are just not exchangable.
The publishing of 3.4.0 to PyPi was an accident, I reverted that.
