This becomes really shaky ground.  Who defines 'forseeable future'? 
Without a solid definition, one can claim stability of their library
or programming language merely by having insufficient foresight.  One
could also easily argue for those that have applications with a longer
lifespan that the length of time between gtk+-1.2 and gtk+-2.x was
very tiny and thus gtk+-2.x would have been in the forseeable future.

Point noted.  Perhaps this is part of what one would use in the
definition of 'foreseeable future'.  :-)
