the dict.iterkeys(), dict.iteritems() and dict.itervalues() methods are no longer supported.

line 93 to:
for brand, regexp in self.BRANDS.items():

What license have you released this under? Can you please include something in the repo to clarify?

MasterCard has just introduced their new Bank Identification Number series, which will start with the number 2. According to their explanation page:

Mastercard® has received an additional range of 2-series numbers to add to the 5-series that we currently provide. The 2-series BINs operate in the same way as the 5-series and we have made changes to our systems to accommodate the new numbers. Readiness for the 2-series across our issuers, merchants and other partners is tracking on target dates listed below. Mastercard customer financial institutions can expect to be issued 2-series BINs starting in 2017.
