Comment 6 for bug 1843700

@Dino, unfortunately as we get further into the v6 development cycle the plugins designed for 5.1 might have problems. The changes to the internal functions in Pcbnew are needed to continue with the feature development, and trying to make it so they are backwards compatible with the Python interface for 5.1 is going to be a nightmare of duplicated code & possible bugs. I believe there is a plan to isolate the Python interface from the internals of Pcbnew so that in the future these sorts of internal changes won't affect the plugins as much, and that will probably require plugins to be rewritten (it isn't known yet what the full API will look like).
