I hope you are doing fine. We have just released a new update for OpenBuildings Designer (10.07.00.105), with that we have OpenBuildings Generative Components (10.07.00.124).
In this new update we have some new features like Packager (replaces the GNT Manager), Operation Node, Value Node, Global Values, Revised Computational Design ribbon. If you want to know more about this update please click on this link.
Also. you can have a look into this video where Wayne Dickerson has nicely described about the new features.
Is there any chance that this release can be separately pushed to OpenBridge / OpenRoads or OpenRail as an update to outdated versions? I think it is important that GC versions embedded in these Bentley platforms are consistent.
Yes, it will be integrated with OBM. We're working into this right now
