Like others have said your docs should be OK. The AIP gets the most changes however if its only a few weeks out it would be very tempting to just use what you have.
For the future you can get all docs on disk and therefore when an amendment is done they send you the new disk, heaps easier.
Most of the guys I know use jepps and use theonline docs or the copies at the office library.
