All languages seem to add more features during their lifetime. I've never 
heard of language in which feature count somehow decreases with later 
versions. If you're happy with the previous version, why upgrade? E.g. 
the existence of Java 5+ or D 2.0 doesn't mean developing code with Java 
1.4 or D 1.x is illegal.
