I apologize for the delay in starting discussions around new features!
We're working on posts that will go into more details, but here's an overview:
Decoupling drivers from LabVIEW releases.
Since we don't have driver support with this Beta, this functionality isn't ready to test, but it will be an important change for LabVIEW going forward, because it means you won't necessarily need to install new drivers when you upgrade to a new version of LabVIEW.
Debugging MATLAB(R) scripts called from LabVIEW.
Configuring the version of MATLAB called by LabVIEW (when you have more than one installed).
Migrating Mathscript code to MATLAB in preparation for the discontinuation of Mathscript.
A tool for viewing the "NI store" NIPM packages used by a LabVIEW project. Unfortunately, this tool didn't make it into the Beta, but I will share the design to get your feedback.
In addition, we are hoping to offer a preview of the Target structure in the next release. This structure integrates RT code on a host VI diagram. We're not ready for general testing of this feature, but I will be asking for volunteers to test and provide feedback.
I had hoped to get Beta testing of the "Rearrange Z-order" methods, but I'm afraid we're going to have to back that feature out, because there are cases (with deferred event handling) where the Z-order change causes a crash, and it's going to be a significant effort to rework the feature.
Independent of any new features, though, I would greatly appreciate loading and running any applications that you can safely run with the Beta, to help us identify potential upgrade issues as early as possible.
