pcb-rnd has added a great amount of complex, large features last year. We 
also started to have our own file format. We are compatible with pcb, but 
we are also compatible with kicad - there's no conceptual difference in 
how we load/save a .pcb file or .kicad_pcb file. The relation of pcb-rnd 
to pcb is going to be more and more similar to the relation between 
pcb-rnd and kicad or other packages. From an user's perspective this means 
pcb-rnd is not a geda/PCB with slightly different config and 2..3 minor 
improvements (like it was in 2013), but it's more of a totally different 
layout package.

In the same time much of the code has been heavily modified, reorganized, 
rewritten or added newly since the fork. If you look at the code you can 
still identify similar parts, but the files (organization of the code), 
the APIs, the data structs changed a lot. And they are going to change 
even more, as I am attacking the good old data representation design 
proplems we couldn't deal with for a decade. For a few months already we 
are no longer API-compatible with geda/PCB plugins. So the two projects 
diverged a lot from developer's point of view as well. For a new 
programmer coming to contribute, pcb-rnd is almost as different from 
geda/PCB as kicad would be.

So if you mean the description doesn't have an emphasis of the history of 
the project, that's intentional: we had a project rebranding a few months 
back when I realized how far we diverged from geda/PCB already. Pcb-rnd 
is historically a fork of geda/PCB, and if you start it up it may still 
look similar for the first glance, but then tons of things differ. Thus 
the emphasis on being a fork is long gone. It's not like we try to hide 
this aspect, it's all in the doc, but this is no longer the main info for 
new users.

Regards,

Igor2
