Not much really. Most of the changes are behind the scenes. Having said that, there are a few minor front end changes, as detailed in the Release Notes for Open-AudIT v4.0.0.
We have disabled Open-AudIT - NMIS integration for the moment. This is one component that we have to rework in order to be compatible. This is coming ASAP. We have implemented the ability to import and export to and from NMIS as below (all available using the GUI, see Manage → Devices → Import from NMIS). What we don't have is the ability to sync between NMIS and Open-AudIT.
