It contains data for languages like Ceylon (2011), Dart (2011), Elixir (2011), F# (2005), Go (2009), Haxe (2005), and Julia (2012). So, no, not decades old. Moreover, Haskell is an old language that has only recently come into the limelight. It's considered new-ish. The study does contain data for languages going all the way back to the 1960s. This is a Good Thing. It means we have a statistically huge sample size which only further supports its validity. In fact, this is the largest study of its kind. Why would anybody want a small sample size that only covers a few languages from the last 20 years???
