Why is the data not updated since 2004??

[ushnish]

zipcode = zcdb[92395] Traceback (most recent call last): File "", line 1, in File "/Users/ushnishde/anaconda/lib/python2.7/site-packages/pyzipcode/init.py", line 167, in getitem raise IndexError("Couldn't find zipcode: '%s'" % zipcode) IndexError: Couldn't find zipcode: 'None'

But 92395 is a valid zipcode. There are other such examples, this data should be updated to at least 2010 onwards.
