I think a huge number of people on these forums are British so be careful to check any answers - I don't think we (in the UK) had much in the way of changes from 2011 to 2012. Or even the early 2013 models! A google should turn up a guy who commuted somewhere around MD during the winter and his range was down to about 45 miles or so when it got cold.
Battery capacity has been largely unchanged on all Leafs since 2010 - range has gone up as they made them lighter and reduced the energy consumption of the heater from mid-2013 (ish, and check the US models carefully as some had the older heater I believe).
