Only the cutting edge is not quite good idea for a project with ~15 y history and a library... there are plenty of software around the world, which use older versions directly or as dependencies.   Plenty of publications citing "we are using version XXX" , which might be 5 or more years old.

Well, that is exactly what the archive is for...
