It definitely looks like Boost is not a stable API ( ). Getting newer versions
added to the EPEL is somewhat hard but doable, but I think that the biggest
issue is that it creates a moving target for EL developers. The purpose of
EL is supposed to be stability and consistency for production environments,
so what's wrong with having a boost141 package in Fedora to allow to a
piece of software to target a known Boost version? To me this seems like
the simplest solution for packages that want to support both EL and Fedora.
