Our Fcom have become electronic books and we have a single manual that covers all the aircraft. When there are differences the relevant chapter has a registration above it. In the old style Fcom there used to be a mod number at the bottom of the page and a decode table at the front of the fcom to tell you what the mod referred to. If you have the new standard there will be a decription of it in the fcom.
The new standard also allows nose wheel steering off the yellow hydraulics.
