you should stop to be an optimist from the moment on things are not 
working as you expected before report problems somewhere and stick at 
stable for any peice of software you use

trying master is only the way to go if you have any problems because 
*then* you can start be an optimist and hope this problems are solved 
but made it not in a release

that's how building of software in general works

don't matter - when they change something in master nobody knows if that 
change is completly finished, will be reverted and so no other projects 
are supposed to change their parts of using a library premature
