The biggest change with this release was to switch to "smart" / "minimal" updating of the displayed sensors ("the fastest updates are the ones you don't do etc"), such that we try to only redraw the ones that have changed in the last sampling interval... look in the code for more detailed commentary plus the actual implementation, but basically this is complicated by the fact that due to the limited icon-sized real estate, the display area is shared between horizontally-adjacent pairs of displayed sensors - so that updating the display of one pretty much forces the re-display of the other, even if only one of them had changed. But hey, we are still doing [at most] 1/4 of the work as previously.
Beyond that, the RXM struct has now become the RXM class, but note that many of the fields were left with public access, as changing all of them over to private would have resulted in much more code churn.
The pre-built binary was compiled and linked using Visual Studio 2022 Version 17.9.2.
