The Debian Project has taken another important step towards better collaboration with its more than 300 derivative distributions by launching the Debian dErivatives eXchange project (DEX). The core idea behind DEX is to reduce the technical differences (informally called delta) between Debian and its derivatives. This is mainly accomplished by easing the integration of patches from derivatives. Making available the patches from all derivatives results not only in a better system for all involved parties, but also eases the workload of the derivatives by reducing the differences derivatives have to maintain themselves.
