OE allows you to build own distributions, so what you are looking at is two different distributions based on different different releases but using same build system ( OpenEmbedded ) over major releases the build system gets changed too in terms of its metadata as well new features and some old cruft removed like usual projects. so you have different releases, and different machines and different distro all contributing to the differences. > > >
