About rpm changes and contrib

Proposed change to rpm4 made me rethink updating contrib packages as flightgear and TeXStudio. The latter had a “light” update texstudio-2.12.6 => texstudio-2.12.8 and flightgear is a simulator I use for fun.

However, it seems rpm4 is going to last to be real in OMV and then I would like to ask if so far rebuilding these packages in OMV LX 3.0.3 is already much different from it use to be in rpm5.
